DEFINITION OF TERMS
Tool: The hydraulic attachment which the auxiliary circuit is intended to power. These
may include hydraulic breakers, compactors, shears, etc.
Operating Pressure: That pressure at which the tool will naturally operate without inuence of outside
pressure relief mechanisms. This pressure is an operating characteristic of the tool
and cannot be altered by the end user without changing the tool design.
Relief Pressure: The relief pressure is that pressure at which the circuit will dump uid in order to
protect itself from damage.
Back Pressure: The pressure at the tool’s connection to the return circuit of the carrier.
Flow Meter: Instrument for testing the operating characteristics of a hydraulic circuit. The data
usually available from this device are pressure (psi/bar), ow (GPM/LPM) and
temperature (°F/°C).
Restrictor Valve: A valve on the ow meter which allows the user to simulate an operating tool by
adding a pressure load (through restriction) to the circuit. This feature is used to
evaluate relief settings and ow ratings at pressure.
V60/V65/V100 Valves: A priority ow control valve manufactured by STANLEY. Allows for optimum opera-
tion of any attachment by providing the proper amount of ow for operation of
the tool the “priority” aspect allows the attachment to function properly if another
control function is activated.
Inlet Flow: The hydraulic oil supplied to the “IN” port of the tool or valve.
Regulated Flow: The ow of oil supplied to the tool by the V60/V100 valve.
By-Pass Flow: The oil ow that is supplied by the carriers pump, but not used in the operation of
the attachment. By-pass ow equals inlet ow (to the valve) minus the regulated
ow.
Pressure Line: The hydraulic line(s) which supply pressurized oil from the pump to the valve or
tool.
Return Line: The hydraulic line which connects the “OUT” port of the tool to the tank circuit of
the carrier.
Cracking Pressure: The pressure at which the relief valve starts to open. Can be seen by a drop in the
ow rate as shown by the ow meter.
Full Open Pressure: The pressure at which the relief valve is completely open dumping all system ow
to the tank.
Ambient Air Temperature: The temperature of the outside air.
Stabilized Temperature: The temperature at which the carrier hydraulic system temperature will stop rising
during testing or operation.

FLOW TEST PROCEDURES
The correct performance of this procedure will verify if
the auxiliary circuit of the carrier is adequate to properly
operate a STANLEY attachment.
This procedure is generic in form. It is the end users
responsibility to ensure that this procedure will work with
his specic type of equipment.
If an adequate ow meter is not available contact your
STANLEY Hydraulic distributor for assistance.
TEST PROCEDURE
1. With the auxiliary circuit completely installed
connect the ow meter between the tool inlet and
outlet hoses.
Note: Always use the hoses that are supplied for the
attachment and make sure the machine hydraulic
oil is between 90° to 120° F. This will assure correct
readings and adjustments.
2. With the machine setting at the mode that’s going to
be used to operate the attachment record the GPM.
GPM = ____________
Note: The relief valve pressure must be greater
than the operating pressure of the attachment and
three times the back-pressure. Never use the relief
valve to control the ow rate in the circuit. Cracking
pressure means the loss of 4 or more GPM.
Record the relief cracking pressure psi.
Example:
Operation pressure of a breaker is 2700 psi. Backpressure is 150 psi. A good rule to follow when setting
the relief, multiply the back pressure by 3 then add this
number to the operation pressure of the attachment.
Operating Pressure 2700 psi
Back-pressure 450 psi
Operating pressure of the tool 3150 psi
The relief valve setting must be greater than the
estimated operating pressure of the tool. If the setting
is lower, damage to the circuit may occur. Excess heat
will be generated in the circuit which will damage the
attachment and carrier.
3. Locate the correct ow for the attachment (page
10). Adjust the machine to the correct GPM.
Note: If possible, always set the machine to the
highest GPM output mode. This will prevent the
operator from over owing the attachments.
4. Once the correct GPM ow is achieved, fully open
the restrictor on the ow meter.
5. With the machine in the attachment mode set in
step 2, record the back-pressure. At this point the
pressure reading on the pressure gauge is the
back-pressure in the circuit. This pressure must not
exceed 200 PSI (13.8 bar).
Back-pressure = psi.
Excessive back-pressure will slow the attachments
operation and lead to premature seal failures and over
heating.
6. Close the restrictor valve on the ow meter until
the attachment relief starts to open (also known as
“cracking pressure”). The relief valve opens when
the ow rate, indicated on the ow meter, begins to
decline rapidly. Locate the tools operating system
relief pressure in the specication section (page
10) in the manual. Adjust attachment relief to
specication.
HEAT LOAD TEST
1. Connect the ow meter between the tool inlet and
outlet hoses.
2. With the carrier set in the attachment mode,
restrict the ow meter until a pressure of 1000 psi
is achieved. This pressure must be maintained
throughout the heat test.
Note: Closing of the restrictor may be required as
the temperature increases.
Monitor the oil temperature from the ow meter until
no change is noted. Record the time required for oil to
stabilize. Record the surrounding temperature (ambient
temperature). Record the time required to stabilize
temperature.
Time to temp. stabilization = ____________ min
Stabilized oil temperature = ____________ °F
Ambient temperature: ____________ °F
“Heat rise” is calculated as the stabilized temperature
minus the ambient temperature.

attachment.
TROUBLESHOOTING
If adequate pump ow is available from the carrier
pumps but is not getting to the attachment, consult your
service representative and review the following:
• Attachment valves are not actuating. Review all
electrical connections that are part of the attachment
kit.
• Ensure proper voltage to the valves.
• Ensure the REG port of the valve is not blocked.
• Check to make sure the carriers main relief is set
to the manufacturers recommendation and that this
value is equal or greater than the attachment circuit
relief.
• If the valve will not turn o, check the drain (tank)
line of the valve to ensure that the pressure is 50
psi or less.
system to make sure the system is operating at the
manufacturers specied capacity and pressure
ratings.
4. Be sure the uid in the hydraulic system is clean.
5. Check the hydraulic lter. Replace the lter if dirty or
deteriorated.
6. Have your STANLEY dealer test the circuit to which
the breaker will be connected to make sure that the
circuit is supplying the specied ow and pressure
rating for the breaker (page 10).
PRE-OPERATION PROCEDURES
NITROGEN CHARGE
The breaker has been properly charged with nitrogen at
the factory and is ready to use.
TOOL BIT LUBRICATION
Grease the top 250 mm / 10 in. of the breaker tool
bit before installing. During operation, the tool can be
greased through the grease tting. Grease is required.
Make sure the tool bit is against the piston by placing
the tool bit against the ground and then putting down
pressure on the breaker. See the illustrations below.
PRE-INSTALLATION INSTRUCTIONS
CARRIER SIZE
Check the Specications section (page 10) of this
manual to determine correct carrier size, hydraulic ow
and pressure requirements.
If hydraulic pressure, hydraulic back-pressure, hydraulic
ow or excavator weight class are exceeded, the tool
warranty is void.
EXISTING EQUIPMENT HYDRAULICS
Using existing equipment hydraulic auxiliary systems
for operating hydraulic tools could cause problems for
the hydraulic tool and the hydraulic system if not set up
properly. Conrm the pressure and ow of the hydraulic
system before connecting the MBF5. Spare spool
valves, dipper circuits, etc., are just a few examples of
easily accessible hydraulic circuits which could cause
problems for hydraulic tool usage.
TEST THE HYDRAULIC SYSTEM

Grease Fitting
Greasing the tool bit without down pressure on the
breaker results in grease lling the space between
the piston and the tool bit. When the breaker is next
activated, the piston will strike the grease at a speed
which will pressurize the grease resulting in seal and
grease zerk failure.

3. When the hydraulic system and breaker are warm,
proceed with operation.
LONG TERM STORAGE
1. Remove the tool bit. Clean the tool stop and the
lower bushing. Thoroughly coat the surfaces of the
tool stop and the lower bushing with grease.
2. If hoses are attached to the breaker, install plugs
on the hose ends. If hoses are removed from the
breaker, install plugs on the hose ends and install
plugs in the breaker IN and OUT ports.
3. Store the breaker in a vertical position. Do not store
the breaker horizontally for extended periods.
OPERATING THE BREAKER
PREPARATION FOR USE
Read the Pre-Operation Procedures, page 13, before
operating a breaker. Failure to follow the preparation
instructions can result in severe damage to the breaker
and carrier and void the warranties of both.
POSITIONING THE CARRIER
BACKHOES
With the breaker tool in place on the material to be
worked, position the backhoe so the boom is halfway up
(45°) and the dipper holds the breaker almost vertical.
Lower the loader bucket until the weight is o the front
tires.
EXCAVATORS
With the breaker tool in place on the material to be
worked, position the excavator so the dipper is at
approximately 45° and the breaker is almost vertical.
The tracks of the excavator should be in line with the
boom and the breaker.
POSITIONING THE BREAKER TOOL ON
THE WORK MATERIAL
Position the tool bit near the edge of the work material,
not in the center or far from the edge. Position the tool 6
– 18 inches (depending on the material) from the edge.
Breaking o smaller pieces of rock or concrete usually
accomplishes more than trying to break larger pieces.
Apply down force to the boom/dipper until the rear of
the backhoe is raised o the ground. Rear tires and
stabilizers should be o the ground so the total rear
weight of the backhoe is on the breaker tool. The breaker
is more ecient when adequate down force is applied.
On at material or rock, the breaker should be vertical
or “curled” back slightly to direct the impact force
downward and toward the backhoe. This directs the
force back toward the edge of the work material. If the
tool is positioned in the center of the work, or too far from
the edge, the energy will be absorbed into the material
without cracking it. Do not run the breaker longer than
15 – 20 seconds. If breakout does not occur within this
MBF5 User Manual ◄ 15
Page 16
OPERATION
Do not break continuously
in one place.
Scoring with the breaker
time, move the breaker to another position.
On at material such as concrete runways, starting to
break in the middle of the material may cause vibrations
to be transmitted throughout the breaker and excavator
because the material has no place to break to. Always
try to start at a point which will permit the material to
break out.
MAINTAIN DOWN PRESSURE
Maintaining hard contact with the surface of the material
to be broken in addition to maintaining adequate “down
force” is very important. Always keep “down pressure”
or “down force” on the point of the breaker by lifting the
wheels, tracks, or stabilizers slightly above the ground.
This method takes the “slack” out of the bracket and
boom pivots, and reduces the impact on the pivots in
the boom.
The operator needs to be constantly aware of the
amount of down pressure being applied and be able
to adjust it if necessary. Not enough down pressure
results in low production and accelerates wear and tear
on the equipment. Too much down pressure may cause
the breaker housing to violently crash into the broken
material when “break-through” occurs.
In any breaking job, the operator should make every
eort to “follow” the breaker with “down pressure” as the
machine breaks farther into the material. The breaker
should be stopped as soon as “break-through” occurs or
if it is apparent that good, solid blows are not occurring.
BREAKING
The operator should note the sound of the blow when
the breaker is running. With experience, the operator
will be able to tell the dierence between a good solid
blow and a hollow sounding blow. A hollow blow means
that solid blows are not occurring and breaker should be
repositioned.
Continuous tool penetration usually does not do much
good. If the material does not break with 3 – 6 inches
of tool penetration, it usually won’t break with full
penetration. The time used for additional penetration
could be better used to strike blows in another place.
Many materials do not respond well to continued
hammering in one place. The breaker tool should be
repositioned on the work each time the tool penetrates
but does not crack the material.
Continuous penetration in the same area for lengthy
periods will create excessive temperatures at the tip
of the tool bit, resulting in loss of temper (hardness)
of the bit, mushrooming of the tip of the bit and may
lead to failure of the bit.
Use a “scoring” method of breaking when cracking
the material becomes dicult. This technique involves
striking the rock or concrete at several places along a
line where you want the crack to occur. Most materials
break sooner when struck several places along a line
than when struck repeatedly in one location. On each
line, the breaker tool should be continually repositioned.
Practice determines the best length of time to stay in
one spot (15 – 20 seconds) and how far to move the
breaker tool.

OPERATION
Breaker tool bit binding
Breaker tool binding can cause erratic breaker operation
and premature wear on the tool shank. Breaker tool
binding is caused by failure to direct the down force in
the direction of the tool bit.
Do not pry with bit and breaker. The tool bit may
break, causing injury.
Excessive side force cocks the tool in its bore, prevents
proper movement and causes premature tool shank and
bushing wear. Since the breaker tool bit must be pushed
up into the breaker to operate, a binding tool prevents
the breaker from operating correctly. Binding also
causes the tool bit and tool bushings to seize and often
results in breakage of one or more breaker components.
Always direct the down pressure force in a line toward
the point of tool contact with the work.
Moving rocks with the tool bit is another method of
binding the tool bit. This practice should be avoided as it
may cause tool bit failure.
Rebar reinforced concrete introduces the problem of
concrete chunks being held together by the rebar after
the concrete has been broken. The best approach to
this problem is to use a chisel point tool which permits
cutting the rebar with the breaker. Another method is to
periodically cut the rebar with an oxy-acetylene torch.
BLANK FIRING
To understand “Blank Firing”, the operator needs to be
aware that the tool bit is able to drop down in the lower
body cavity, far enough so that the piston cannot strike it,
when the tool bit is not in contact with the work surface.
“Blank Firing” occurs whenever the breaker is operating
and the piston is not able to strike the tool bit solidly or not
strike the tool bit at all. “Blank Firing” accelerates wear
and tear on breaker and carrier components and may
result in failure of one or more components. Excessive
“Blank Firing” may be considered equipment abuse and
may result in voiding warranties.
Break-through or dicult surface contact results in
“Blank Firing” when the material being broken fractures
and the tool bit is no longer in “hard contact” with the
material but is still pushed high enough in the lower body
cavity so that the piston can strike it. In this position,
the piston strikes the tool bit and the tool bit, in turn,
is driven against the retaining pins because it is not in
sucient contact with the material to be broken. The
energy is absorbed by the retaining pins, other breaker
components, and the carrier boom components. “Blank
Firing” of this type can be experienced in trench work
where obtaining striking contact with the work surface is
dicult or the wrong tool bit is used, or in at rock work
where the operator fails to stop operation of the breaker
when slippage, fracturing or material break-through
occurs.
“Blank Firing” as a result of operator error occurs when
the tool bit is not in contact with the work surface to be
broken and is allowed to drop down in the lower body
cavity so that the piston is not able to strike it. Instead, the
downward movement of the piston will be stopped by an
internal oil cushion located at the bottom of the piston’s
stroke and the energy of the piston will be absorbed by
breaker components and excavator boom components.
“Blank Firing” of this type can be experienced when the
operator fails to stop operation of the breaker when the
material fractures or material break-through occurs, or
during re-positioning of the breaker.
While “Blank Firing” cannot always be avoided, it can be
kept to a minimum by avoiding the above conditions as
much as possible.
UNDERWATER USAGE
Underwater usage of the breaker will cause damage
to internal components. Even if the breaker is partially
submerged, water is introduced to an area between
the tool bit and piston. On the piston down cycle, the
water becomes compressed and damages adjacent
components.
MBF5 User Manual ◄ 17
Page 18
Do not use underwater without supplying air to breaker.
DO NOT USE UNDERWATER
OPERATION
No part of the breaker may be submerged in water.
Underwater usage of the breaker will cause
internal damage to the breaker. Consult STANLEY
for modications and specic warranty coverage if
you have an underwater requirement.
GREASE THE BIT
Grease should be applied to the upper end of the
breaker tool bit each time it is installed. Thereafter, the
tool should be greased at the tting to reduce wear in
the lower body and bushings of the tool. See “Tool Bit
Lubrication” on page 13.

TROUBLESHOOTING
This section describes how to nd and resolve problems users may experience. If a situation occurs that is not
covered, call your STANLEY Customer Service Representative for assistance.
Inspecting the tool or installing parts with the hydraulic hoses connected can result in severe personal injury
or equipment damage. To prevent accidental startup, disconnect the hydraulic power before beginning any
inspection or installation task.
If symptoms of poor performance develop, the following chart can be used as a guide to correct the problem.
When diagnosing faults in operation of the tool, always check that the hydraulic power source is supplying the
correct hydraulic ow and pressure to the tool as listed in the tool specications (page 10). Use a owmeter
known to be accurate. Check the ow with the hydraulic oil temperature at least 80° F/27° C.

MAINTENANCE
DAILY MAINTENANCE CHECKS
• Check for loose or missing fasteners. Tighten or
replace as needed.
• Inspect tool retaining pins and pockets for wear.
• Check for hydraulic leaks at all ttings and hoses.
Replace any defective hoses.
• Apply grease to the grease tting in the lower body.
Grease as needed throughout the day.
TOOL STOP AND LOWER BUSHING
Inspect the tool stop and lower bushing for excessive
galling and metal pickup on the tool bit. Also check for
cracks. If cracks are present, the part must be replaced.
The extent of wear of the tool stop and lower bushings
and the tool bit can be checked by moving a NEW tool
bit back and forth and measuring the gap between the
tool bit and the lower bushing. If the gap is more than
.250 in./6 mm, the upper bushing, lower bushing and
tool bit should be replaced. A gap in excess of .250 in./6
mm will cause damage to the piston. Do not just replace
the tool bit or the lower bushing individually as this will
result in premature wear of the replaced component. It is
recommended to replace ALL worn components.

CHARGING THE ACCUMULATOR
The tools required to charge the breaker accumulators
are the 505232 charge hose assembly and the 28257
accumulator tester, which are used with other STANLEY
model breakers. When charging the accumulators,
make sure the tools and charge valves are clean. Dirt
can contaminate the charge valves and cause leakage.
1. Remove the protective plug from the accumulator
charge valve.
Note: There is one accumulator on this breaker; the
upper accumulator.
2. Hold the chuck end of the tester and turn the gauge
fully counter clockwise to ensure the plunger inside
the chuck is completely retracted.
3. Screw the tester into the breaker charge valve by
turning the chuck. Do not use the gauge for turning
as this will advance the plunger in the chuck. Tighten
the chuck lightly against the breaker charge valve.
4. Turn the gauge clockwise to advance the plunger
until a pressure is indicated on the gauge. Do not
overtighten.
5. If the pressure is correct, unscrew the gauge to
retract the plunger. Then, loosen and remove the
tester from the charge valve. If the pressure is not
correct, proceed to step number 6.
Note: When disengaging the tester a "POP" of
nitrogen is normal.
6. Connect the charge hose assembly to the charging
valve on the tester. Make sure the valve on the
charge hose assembly is closed. Open the valve on
the nitrogen bottle.
7. Very slowly open the valve on the charge hose
assembly and slowly meter the nitrogen into the
breaker charge valve until the tester reads a
pressure of 200 psi.
8. Close the valve on the charge hose assembly and
on the nitrogen bottle. Unscrew the gauge to retract
the plunger. Loosen and remove the tester from the
charge valve. Before replacing the protective plug,
inspect the plug O-ring. If damaged or deformed,
replace the plug. Apply Loctite™ 243 to plug and
cap.

PROPER CARE OF TOOL BITS
Tool bits are made and heat treated to specication.
Tool bits are wear parts and are used in the most
destructive applications. Even when the hydraulic
breaker is used properly, and the operator is
experienced, a tool bit may become damaged. When a
tool bit has been damaged, it is useful to determine the
cause immediately in order to prevent the damage from
occurring again.
All STANLEY tool bits are machined and hardened for
maximum performance. Care must be taken to maintain
the tools original condition for optimum productivity and
life expectancy. It is not uncommon for an operator, who
is unfamiliar with using a hammer, to break a bit. This is
part of the learning experience.
Listed below are several methods to determine tool
failure and will quickly aid in warranty determination.
TOOL FAILURE NOT COVERED
UNDER WARRANTY
BLANK FIRING OR FREE RUNNING
This occurs when the tool is not in proper contact with
the work, thus causing the energy produced by the
hammer to be concentrated on the tool retainers and the
retainer slots on the tool itself. Caution should be used
to prevent the hammer from sliding o slanted surfaces
or when breaking through thin material.
The illustration below is typical of the kind of breakage
that occurs from excessive blank ring.
METAL-TO-METAL CONTACT
Extreme caution should be used to avoid scratches or
gouges on the surface of the tool. These areas create a
stress concentration metal-to-metal contact point, thus
weakening the tool.
Another form of metal-to-metal contact is galling, which
usually occurs from the lack of lubrication. Special care
should be taken to lubricate the tool shaft every two to
three hours.
Steel failures that were caused by surface damage take
two main forms. The simplest form is caused by deep
scratches on working steel surface. The broken surface
has a shell pattern around the starting point of failure,
similar to fatigue failure. The other parts of the broken
surface are brittle. These failures work slowly through
the steel until it suddenly fails completely.
The second form surface damage failure occurs when
there are deep scratches on working steel surface and
there was also excessive bending stress. The broken
surface also shows the shell pattern, but the other parts
of the broken surface are brittle and usually have a “lip”,
like that in a stress failure.
WORN-OUT FRONT BUSHING(S) OR
RETAINER PIN(S)
Worn-out front bushings will cause the tool to become
misaligned inside the hammer. This misalignment will
cause uneven contact between the piston and tool, thus
causing stress to concentrate on one particular area of
the tool. This can also cause the tool to bind inside the
hammer.
Worn-out retainer pins will cause uneven loading on the
pins themselves, causing failure of the tool or retainer
pins. This will also cause excessive wear to the front
bushings.
In extreme cases, the combination of surface damage
and severe bending can quickly break even the best
working steels.
The illustrations below show examples of severe stress
breaks.
MBF5 User Manual ◄ 23
Page 24
PROPER CARE OF TOOL BITS
PRYING
This is the most common cause of tool failure. Even
when there is no surface damage, the stress from prying
can easily break a working steel. This kind of failure
generally results from any type of side pressure such
as an incorrect breaking angle or from using the tool to
reposition material. The tool should not be used as a
pivot point when repositioning the carrier. The power
generated by the carrier will far exceed the strength of
the tool.
CORROSION
Tools should be greased and stored out of the weather.
Corrosion will accelerate fatigue fractures.
MUSHROOMING
Driving the tool into hard material for a long period of
time generates intense heat, indicated by a blue tone just
above the point. This heat will soften the steel and cause
the point to fold over, or mushroom, the end of the bit.
Avoid hammering in one location for too long. If material
does not break after a short period (approximately 15 to
20 seconds), reposition the tool.
If the overheated steel is suddenly cooled by being
dipped in water, the metal will harden and become brittle.
The illustration shows some examples of failure caused
by temper changes.
Similar failures can also occur when the steel is used
with extreme down pressure and the steel repeatedly
slips o the work at an angle, or the material itself moves
from under the working steel.
As the next illustration shows, fatigue failures take many
forms, but they all exhibit similar features. Generally, the
broken surface is brittle and has a “lip” like that in the
bending failure, even though, in some cases, the lip has
been broken.
24 ► MBF5 User Manual
TOOL FAILURE COVERED UNDER
WARRANTY
INTERNAL MATERIAL FLAW
This failure occurs when a foreign material is rolled into
the steel during the manufacturing process, causing an
imperfection in the internal material grain. The result is
an inherent weakness in the tool shank and eventual
breakage.
The broken surface exhibits a shell pattern at the point of
failure. The other parts of the broken surface are brittle.
This is the only kind of tool bit failure that is always
covered under warranty.
Working steel failures can be diagnosed by looking at
the break itself and at the place on the steel where the
break occurred. Discoloration, like “rainbow” eects or
blue bands, is the result of extreme heat.
Page 25
PROPER CARE OF TOOL BITS
Look for surface cracks, galling or gouge marks. Breaks
that start as surface damage have a “sea shell” pattern,
with the damaged spot at the center. A large “sea shell”
indicates a slow growing break; a small one indicates a
break that has been compounded by side stress.
Stress failures start small, and spread into the center
of the steel. In a stress failure, the coarser the grain,
the greater the stress was, and the more rapid was the
failure.
• Failures in this area are usually the result
of blank ring, worn bushings, worn
retainer pins or the lack of lubrication.
• Failures in this area are usually the result
of worn retainer pins or blank ring.
• Failures in this area are usually the
result of prying, metal-to-metal contact or
corrosion. Prying failures often exhibit a
shell-like formation near the edge of the
steel diameter where the break began, and
a “tail” opposite that where the remaining
steel bent and tore.
• Failures in this area are usually the result
of heat build-up, mushrooming or improper
contact with the work.

PROPER CARE OF TOOL BITS
STANLEY breakers are available with several dierent types of tool bits. The most common are the moil, chisel and
blunt. Each of these working steels has its own purpose as described below.
To obtain the maximum production from the breaker, it is important to select the proper working steel. Consult your
STANLEY representative for assistance in selecting the proper working steel for your application.
MOIL
This is by far the most popular working steel. It is a general purpose point used to break
anything from concrete to hard rock. Its pencil-type point is used to fracture the material.
The tool is best where penetration speed is important.
CHISEL
This style of point is generally used for trench work, where a controlled break is required,
and for rock breaking on materials with a denite line of cleavage. A chisel bit also works
well in softer concretes where a moil might penetrate quickly, but not cause a fracture line.
BLUNT
This at type of bit is used to break softer material such as coal or shale. A moil or chisel
will tend to punch holes in this type of material, where a at blunt will shatter the material. It
is also useful when breaking irregularly shaped material where its broad tip makes it easier
to position.
