GENERAL SAFETY RULES — FOR ALL POWER TOOLS

WARNING!

READALLINSTRUCTIONS

Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. The term "power tool" in all of the warnings listed below refers to your mains-operated (corded) power tool or battery-opearted (cordless) power tool.

SAVE THESE INSTRUCTIONS

 

WORK AREA SAFETY

 

 

 

POWER TOOL USE AND CARE

 

 

 

 

 

 

 

 

 

 

1.Keep work area clean and well lit. Cluttered or dark areas invite accidents.

2.Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.

Power tools create sparks which may ignite the dust or fumes.

3.Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

4.Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.

5.Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

6.Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

7.Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool. Keep cord away from heat, oil, sharp edges, or moving parts. Damaged or entangled cords increase the risk of electric shock.

8.When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

PERSONAL SAFETY

9.Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.

10.Use safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

11.Avoid accidental starting. Ensure the switch is in the offposition before plugging in. Carrying tools with your finger on the switch or plugging in power tools that have the switch on invites accidents.

12.Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.

13.Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

14.Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts.

Loose clothes, jewellery, or long hair can be caught in moving parts.

15.If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of these devices can reduce dust-re-

16.Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.

17.Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

18.Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the tool accidentally.

19.Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tools or these instructions to operate power tools. Power tools are dangerous in the hands of untrained users.

20.Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool's operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

21.Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

22.Use the power tool, accessories and tool bits etc., in accordance with these instructions and in the manner intended for the particular type of power tool, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

SERVICE

23.Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

lated hazards. page 2

SPECIFIC SAFETY RULES

1.Hold power tools by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a "live" wire will make exposed metal parts of the tool "live" and shock the operator.

2.Wear ear protectors with impact drills. Exposure to noise can cause hearing loss.

3.Use auxiliary handles supplied with the tool. Loss of control can cause personal injury.

4.Maintain tools carefully. Keep handles dry, clean and free from oil and grease. Keep cutting edges sharp and clean. Follow instructions for lubricating and changing accessories. Periodically inspect tool cords and extension cords for damage. Have damaged parts repaired or replaced by a MILWAUKEE service facility.

5.Maintain labels and nameplates. These carry important information. If unreadable or missing, contact a MILWAUKEE service facility for a free replacement.

6.WARNING! Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

lead from lead-based paint

crystalline silica from bricks and cement and other masonry products, and

arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specifically designed to filter out microscopic particles.

7.Always use anchor bolts to secure the base on cracked, uneven, porous or vertical surfaces.

8.Diamond coring equipment requires the use of water. Since the use of electrical equipment in wet areas is hazardous, the equipment must be grounded (see "Grounding"). Wear insulated footwear and gloves for extra protection against shock hazards.

9.Provide proper protection for people and property below the coring area when coring through floors.

10.A meter box must always be used with Diamond Coring Equipment so that amperage can be monitored. See "Accessories".

GROUNDING

WARNING!

Improperly connecting the grounding wire can result in the risk of electric shock. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the cord or plug is damaged. If

damaged, have it repaired by a MILWAUKEE service facility before use. If the plug will not fit the outlet, have a proper outlet installed by a qualified electrician.

MILWAUKEE Dymodrills are provided with a 20 amp locking plug (NEMA

L5-20). MILWAUKEE meter boxes may be provided with either a 20 amp locking or a 30 amp (NEMA L5-30) locking plug depending on the model .

Grounded Tools:

Tools with Three Prong Plugs

Tools marked “Grounding Required” have a three wire cord and three prong grounding plug. The plug must be connected to a properly grounded outlet (See Figures A and B). If the tool should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user, reducing the risk of electric shock.

The grounding prong in the plug is connected through the green wire inside the cord to the grounding system in the tool. The green wire in the cord must be the only wire connected to the tool's grounding system and must never be attached to an electrically “live” terminal.

Your tool must be plugged into an appropriate outlet, properly installed and grounded in accordance with all codes and ordinances. The plug and outlet should look like those in Figures A and B.

Double Insulated Tools: Tools with Two Prong Plugs

Tools marked “Double Insulated” do not require grounding. They have a special double insulation system which satisfies OSHA requirements and complies with the applicable standards of Underwriters Laboratories, Inc., the Canadian Standard Association and the National Electrical Code. Double Insulated tools may be used in either of the 120 volt outlets shown in Figures C and D.

Fig.A

Fig.C

Fig.D

EXTENSIONCORDS

Grounded tools require a three wire extension cord. Double insulated tools can use either a two or three wire extension cord. As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage. Refer to the table shown to determine the required minimum wire size.

The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14 gauge cord can carry a higher current than a 16 gauge cord. When using more than one extension cord to make up the total length, be sure each cord contains at least the minimum wire size required. If you are using one extension cord for more than one tool, add the nameplate amperes and use the sum to determine the required minimum wire size.

Guidelines for Using Extension Cords

If you are using an extension cord outdoors, be sure it is marked with the suffix “W-A” (“W” in Canada) to indicate that it is acceptable for outdoor use.

Be sure your extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualified person before using it.

Protect your extension cords from sharp objects, excessive heat and damp or wet areas.

Mounting the Meter Box

For All Catalog Nos. (Fig. 3 & 4).

A meter box is standard equipment with the Vac-U-Rig®, but it must be purchased separately for other Dymorigs (see "Accessories"). Attach the meter box to the cradle on the side opposite of the handle.

1.Slip the collar on the meter box over the stud on the cradle.

2.Position the meter box as desired and tighten the 1/4"-20 threaded socket head screw.

NOTE: For horizontal (wall) coring, the ammeter gauge must face upward in view of the operator. Otherwise, water flow from the water shut-off valve might drip into the outlets on the meter box.

Mounting the Dymodrill Motor to the Stand

For All Cat. Nos. (Fig. 5 & 6).

Dymorigs include a mounting bracket which mounts Dymodrill motors to the stand. An optional spacer assembly is available (see "Accessories"), which can be used when coring with any bits; but it must be used with any bit over 10" (outside diameter).

1.To mount the motor, loosen the cradle lock. Raise the cradle on the column using the spoked handle to allow room for installing the bit later. Tighten the cradle lock.

NOTE: If the cradle is difficult to move on the column, loosen the gib screws (see "Adjusting the Gib Screws").

2.Fasten the mounting bracket or the optional spacer assembly to the Dymodrill (Fig. 5) motor using the four (4) 1/4"-20 threaded socket head screws and four (4) lock washers (they are the smaller of the two provided in separate accessory bag). Make sure the square key on the mounting bracket or spacer assembly engages with the slot on the Dymodrill motor.

3.Fasten the mounting bracket (or optional spacer assembly) and motor assembly to the cradle slot (Fig. 6) by inserting the four (4) 3/8"-16 threaded socket head cap screws and lock washers (they are the larger of the two provided in separate accessory bag) through the cradle. Place screws through the holes from the other side of the Dymorig and place lock washers on the side of the mounting bracket.

After the Dymodrill motor is mounted, make sure the cradle is rigid against the column to prevent the motor or bit from wobbling during coring. Before coring, try to wiggle the cradle and motor with your hands. If the cradle is secure, it should not move. If it does move, tighten the gib screws that secure the cradle to the column (see "Adjusting the Gib Screws").

Methods for Securing Equipment to Work Surface

WARNING!

To reduce the risk of injury always secure the rig to the work surface to help prevent personal injury and to protect the rig. An unsecured rig could rotate during coring and possibly cause injury.

NOTE: Some building materials contain steel reinforcements.

MILWAUKEE Dymobits can cut through embedded steel, but are not recommended for coring solid steel plates.

Horizontal Coring (walls)

For specific instructions on using anchors, see "Using an Expansion-

Type Anchor".

WARNING!

To reduce the risk of injury always use an expansion-type anchor during horizontal coring. Vacuum systems can slip when used on a vertical surface.

Vertical Coring (floors)

Two methods will work to secure the rig for vertical coring: either an expansion-type anchor OR a vacuum pump and vacuum pad system. Securing the rig with an anchor gives better bit performance because the attachment is more rigid. For specific instructions on assembling the vacuum system, see "Assembling and Using a Vacuum System".

Optional Telescoping Assembly

The telescoping assembly can be used to supplement either securing method.

NOTE: Vac-U-Rig® Cat. No. 4136 includes a vacuum pump and vacuum pad. However, for some applications, you may choose to use an expan- sion-type anchor to secure the tool.

Anchors and Telescoping Assembly are not supplied with any of the above rigs. Telescoping Assembly can be purchased separately (see “Accessories”). Anchors unavailable through MILWAUKEE.

One vacuum pad is supplied with the Vac-U-Rig® and they can be purchased separately for other Dymorigs. The vacuum pad is most effective when it is secured to a relatively smooth surface such as poured concrete. If the surface is too porous or rough, the pad may not hold securely. Before using a vacuum pad, always check the gasket on the underside of the pad to make sure it isn't worn, cracked or torn. If it is, immediately replace the gasket, otherwise the vacuum pad may not hold the rig securely. To replace the gasket, see "Replacing Vacuum Pad Gaskets" in the "Maintenance" section. See "Accessories" for gasket part number.

1.To use the vacuum pad, tilt the base of the rig and slide the vacuum pad under it so the threaded stud goes through the hole on the end of the center slot on the base. Then set the stand upright.

2.Position the rig as required for coring the hole.

3.Level the rig with the four (4) leveling screws using the bubble level

(4125 & 4130 only) as a guide. When the rig is level, tighten the four

(4)nuts (4125 & 4130 only) on the leveling screws.

4.Connect one end of the supplied vacuum hose to the vacuum line coupler on the vacuum pad. To do this, pull back the collar on the hose and push the end of the hose onto the coupler until in snaps into place. Then, connect the other end of the vacuum hose to the coupler on the vacuum pump following the same procedure.

5.The vacuum pump may be set on a dry surface away from the rig or mounted to the base of the Dymorig as shown. However, DO NOT mount the vacuum pump to the Dymorig when angle coring.

To mount the vacuum pump on the Dymorig, place the small hole on the vacuum pump mounting bracket over the vacuum pad stud on the Dymorig.

6.Plug the vacuum pump into the power source—the pump will start automatically. Step on the vacuum pad or the vacuum pad stud until the vacuum pad lowers and adheres to the work surface.

7.After the pad is secured to at least 20 inches of mercury vacuum, tighten the vacuum pad nut securely.

WARNING!

The vacuum gauge must read a minimum of 20 inches of mercury vacuum. To reduce the risk of injury DO NOT CORE if the gauge reads less than 20 inches of mercury vacuum.

To do this, pull back the collar on the hose and push the end of the hose onto the coupler until it snaps into place. Connect the other end of the vacuum hose to the coupler on the vacuum pump following the same procedure.

5.The vacuum pump may be set on a dry surface away from the rig or mounted to the base of the Dymorig as shown. To mount the vacuum pump on the base, place the small holes on the vacuum pump mounting bracket over the two tapped holes on the base. Attach the vacuum pump to the base with two (2) 1/4" - 20 screws supplied in the accessory bag.

6.Plug the vacuum pump into the power source - the pump will start automatically. Step on the base until it lowers and adheres to the work surface.

7.Tighten the four (4) leveling screws only enough to eliminate rocking. Over-tightening can lift the gasket off the ground and release the vacuum.

WARNING!

The vacuum gauge must read a minimum of 20 inches of mercury vacuum. To reduce the risk of injury DO NOT CORE if the gauge reads less than 20 inches of mercury vacuum.

Using the Optional Telescoping Assembly

1.Secure the rig using either an expansion-type anchor or a vacuum system (see "Securing the Equipment to the Work Surface").

2.Place the top flange of the extension against a ceiling or wall and place the other end on the jack screw at the top of the Dymorig column.

The assembly is adjustable up to 14 feet. Turn the jack screw to tighten the assembly and to make small adjustments.

Supply an Adequate Water Flow

An adequate supply of water must flow freely and constantly during the entire cut. Dymodrills are equipped with a built-in water shut-off valve to allow water to flow down the inside and up around the outside of the bit.

This acts to cool the bit and flush cuttings from the hole.

Reading the Meter Box (Fig. 16)

Fig

15

The ammeter is the dial indicator on the meter box, which is standard equipment with the Vac-U-Rig® and can be purchased separately for other Dymorigs. The ammeter provides pressure feedback during coring, allowing you to help prevent motor overload and premature bit wear. The green area on the ammeter is the operating range and the red area indicates that you are applying too much pressure.

WARNING!

To reduce the risk of injury, always use Dymodrills in conjunction with meter boxes. Meter Boxes provide a switch to turn the Dymodrill motor OFF and ON and an optimum operation range to help prevent motor overload.

Shear Pin and Clutch (Fig. 17)

Spindle Sleeve

(Shear pin models)

Threaded Spindle

(Clutch Models)

Retaining Ring

(shear pin model only)

Dymodrill Nos. 4079, 4090, and 4094 contain a shear pin to protect the gear and motor against overload. This pin drives the spindle sleeve. If the bit binds, the pin will shear to prevent gear and motor damage. Extra shear pins are supplied with each Dymodrill and can be replaced (see "Accessories" for part numbers). It is important to check the condition of the spindle before using the tool each time. The spindle must be smooth without grooves or pitting. If the spindle is not in good condition, it is possible for the threaded spindle sleeve and the internal spindle to weld together and seize during coring (see "Lubricating the Spindle for Dymodrills with a Shear Pin" in the "Maintenance" section for spindle lubricating instructions).

Cat. Nos. 4004, 4005, 4092, 4096 and 4097 feature a friction clutch rather than a shear pin to protect the motor and gears. If the motor overloads, the clutch will begin to slip and the bit will stop rotating. The clutch is factory-set and does not require adjustment. Nuisance (frequent) clutch slippage should be addressed by an authorized

MILWAUKEE service center.

WARNING!

To reduce the risk of injury, always check the work area for hidden wires before coring.

Coring Procedure (Fig. 18)

1.Select and install a bit following guidelines in "Selecting and Installing a Core Bit".

2.Secure the rig to the work surface using one of the methods described in "Methods for Securing Equipment to Work Surface".

3.With the motor OFF, adjust the gear to either high or low speed according to the guidelines in "Selecting Speeds".

NOTE: DO NOT SHIFT SPEEDS WHEN THE DYMODRILL MOTOR IS ON. To adjust the speed on all Dymodrills, move the gear shift lever to the desired setting.

4.Connect the water hose to the Dymodrill water shut-off valve and to the water supply. Make sure the seal is watertight. Use a standard garden hose if you require additional length. Set up a water collection system.

5.If you are using a vacuum system, read the instructions for specific setup in "Assembling & Using a Vacuum System".

Do not continue the following steps until the vacuum gauge reads at least 20 inches of mercury vacuum. Never operate the Dymodrill if the gauge reads less than 20 inches (see "Mothods for Securing

Equipment to Work Surface"). Always monitor the vacuum gauge during coring. If water collects in the vacuum pump filter jar, empty it to prevent damage to the pump.

WARNING!

To reduce the risk of injury, do not operate the Dymorig if the gauge reads less than 20 inches of mercury vacuum.

6.Turn the Dymodrill motor ON. Turn the water on so it flows freely through the water shut-off valve (see "Supply an Adequate Water

Flow"). Turn the valve clockwise to increase water flow and counterclockwise to decrease water flow.

7.While holding the handle, slightly loosen the cradle lock handle and slowly rotate the handle to lower the bit into the workpiece, applying steady, even pressure. To help reduce bit wandering, always use a light load to start the hole and wait for the tip of the bit to penetrate the work surface completely before increasing the load.

8.Use sufficient pressure so the bit cuts constantly. Use the ammeter on the meter box as a guide for proper pressure.

NOTE: If the rig shifts during coring, stop the motor, reposition the rig and resume coring.

9.Monitor the water flow (see "Diamond Coring"). Generally, water should flow at a rate of approximately one to two gallons per minute. If the water flow is too heavy, the two holes in the water swivel housing will leak. If that happens, reduce water flow. Water flow is adequate when the water and cuttings are flushed in a circular pattern about 1/2" around the bit. Keep the work area dry.

10.When the cut is complete, keep the drill motor ON and rotate the handle clockwise to remove the bit. The bit may become stuck in the hole if you turn the motor OFF before the bit is completely removed.

Once the bit is removed from the work surface, turn the motor OFF. Tighten the cradle lock handle. Unplug the meter box from the power supply before removing the vacuum pump to prevent accidental starting of the motor when the vacuum pump is released.

If you are using a vacuum pump, unplug it and open the vacuum release valve to release the vacuum.

Retrieving Cores and Deep Coring

When coring holes that are longer than the core bit, follow the steps below.

1.Begin coring the hole as usual. When you have cored to the length of the bit, stop the Dymodrill motor.

2.Remove the core by driving a chisel or slender wedge into the cut between the core and the work surface. You may also use a special core tongs, bent wire or anchor bolts to remove the core.

3.After removing the core, reinsert the bit or use a bit extension and continue coring (see "Accessories"). Removing cores with diameters greater than twice their length can be difficult. One method to remove such cores is to first break the core into smaller pieces and then remove the pieces. Electric hammers and chisels are ideal for breaking cores.

WARNING!

When coring through floors, cores generally drop from the bit. To reduce the risk of injury, provide proper protection for people and property below the coring area.

Diamond Coring

Factors that influence diamond core performance:

Amount of coolant

Dymorig rigidity

Dymorig condition

RPM of drill motor

Feed pressure applied to bit by operator

Amount of steel

Size of embedded steel

Age of concrete

Aggregate (size, type, hardness, abrasiveness)

Type of sand–manufactured vs. river (natural)

Operator technique

Operator care

Bit runout

Operator Technique

Core with consistent, firm feed pressure. Do not subject the bits to sudden impacts. Uneven feed rate cracks diamonds. Low feed pressure polishes diamonds, slows penetration and contributes to bit glazing. High feed pressure can overload the drill motor or can cause diamonds to pull out prematurely, particularly when coring embedded steel. Make the bit work, but do not try to jam the bit through the material.

If vibration occurs:

1.Stop drilling.

2.Turn motor off.

3.Check for loose bolts, nuts and gib screws. Tighten if required.

4.Check for bit runout. Replace if required.

If vibration continues to occur, remove the core and loose material.

If vibration continues to occur after attempting these measures, return the rig to the nearest MILWAUKEE service facility.

page 11

Water

Water provides two main benefits during coring:

1.Water acts as a coolant, eliminating the heat caused by the friction of the coring action. This preserves the integrity of the diamonds, the bond matrix, the segment solder, and core tube. Without a coolant, the heat buildup during coring can cause all of these components to fail.

2.Water flushes loose, abrasive particles created during coring. These particles consist of aggregate, sand, diamond particles and various metals from embedded steel and the core bit matrix. The hole must be free of debris to allow the core bit to work. If loose particles are not properly flushed from the hole, an unnecessary drag will occur along the side of the core barrel. This can contribute to bit glazing through lack of power as well as motor damage through amperage increases due to bit resistance. In addition, loose particles tend to wear the bit tube, which can eventually result in the loss of segments.

Monitor water flow. Water volume should be adjusted until water return is a muddy, solid color. Clear water or clear streaks indicate too much water volume. Excess water is a leading cause of bit glazing and failure. Other factors contribute to glazing, but water adjustment is one of the most easily controlled by the operator. Excessive water prevents adequate segment/material contact. When the bit segments do not properly contact the work surface, the desired "controlled erosion" effect which maintains bit sharpness does not occur and the bit begins to glaze. This happens especially with smaller diameter bits. Adequate water volume varies according to the bit diameter. Use only enough water during coring to flush the cuttings from the work surface.

Equipment

Make sure machinery is in good operating condition. The column, carriage, motor connection and base should all be firmly connected and should not vibrate during coring.

Motors should be of proper size (amperage and RPM) for the diameter of the core bit used. Consult motor guide in catalog.

Always make sure the Dymorig is rigidly mounted with an anchor or vacuum; any movement or vibration will shorten the life of the core bit. Standing on the rig's base as a form of anchoring is dangerous and does not provide the necessary rigidity.

Diamond Core Bits

For the first 2 or 3 holes, use light feed pressure, so the new diamond gradually breaks in.

Lower the bit very slowly onto the work surface. Use light feed pressure until the bit crown has penetrated or "seated" into the material.

If the core bit encounters embedded steel, slow down the feed pressure and let the bit core at its own pace. Don't force the bit.

Typically the water around the bit will clear when embedded steel is encountered. Do not allow any vibration whatsoever or severe diamond breakage or pullout will occur.

Keep bits sharp.

Bit Glazing & Diamond Core Motor Shear Pins

Bit binding is caused by one of two things: a dull (glazed) bit or a poorly stabilized rig.

Causes of bit glazing:

Wrong RPM for bit diameter

High feed pressure

Low feed pressure

High steel content in work surface

Large, hard aggregate

Too much water

Low motor power

A sharp bit typically has good diamond exposure and will cut/grind almost anything in its path, including embedded steel.

Sharpening Procedure for Core Bits

To work efficiently, diamond core bits must maintain good diamond exposure. Many factors work together to provide the "controlled erosion" cycle of the tool's segment to occur. When this "controlled erosion" cycle is altered, the bit can become dull or "glazed." Glazing becomes noticeable when the coring feed rate slows dramatically or the bit does not cut.

Examine the bit immediately. If the diamonds are flush with the metal, they are underexposed or "glazed."

The following steps will often correct the problem:

1.Reduce water flow until it becomes very muddy. Continue using as little water as possible until penetration increases.

2.If the bit does not open up, remove from hole. Pour into the kerf a thick (1/4") layer of silica sand (the coarser the better).

3.Resume drilling for approximately 3 to 5 minutes with very little water and at a lower RPM if possible.

4.Gradually increase water flow to flush sand from kerf.

5.Repeat as needed.

The Effects of Steel in Coring

To self-sharpen, diamond-impregnated core bits require interaction with an abrasive material. This abrasive material wears away the metal composition in the segment's matrix. As this is done, sharp diamonds are exposed and the grinding action created by the diamonds continues.

Embedded metal (rebar) is not an abrasive material. It does not provide the degree of abrasiveness required for matrix wear to occur and expose sharp diamonds embedded in the segment's matrix.

A high degree of exposure to embedded metal by the bit's segments creates glazing. Glazing prevents the bit from cutting and coring.
