Operations
Note
THOROUGHLY READ THROUGH THE ENTIRE MANUAL BEFORE
OPERATING THIS MACHINE!
PURPOSE
Ø The purpose of the TYP-28A is to drill through steel using annular cutters or ¾”
Weldon shank type drill bits.
Ø These drills are designed to magnetically adhere to a ferrous surface using their
electromagnetic base. Generally these drills are designed and used to drill through
mild steel. This magnetic base will not work without a power connection.
o NOTE: The entire magnetic base must cover the work area to have full
magnetic adhesion. Using only a portion of the magnet is dangerous! Make
sure the base fits completely on the surface.
Ø These machines can be used vertically, horizontally or overhead (inverted) provided
strong enough magnetic adhesion and an acceptable work environment. NOTE: For
safety, the safety chain should always be used incase of an accidental power failure
or other loss of magnetic adhesion.
OPERATIONAL PRINCIPLES
Ø The main drilling shaft rotates in the forward direction. The main drilling motor
connects to the tool holder to make contact with a surface and slowly bore a hole.
Using the feed handles on the side of the drill, the user can raise or lower the drilling
motor.
MACHINE COMPONENTS
Ø The main components of the TYP-28A are the tool holder, gearbox, motor, frame and
magnetic base. The tool holder is driven by the gearbox and the motor.
o These components must be not be removed except by a qualified technician.
Power must be disconnected prior to any service.

TRANSPORTING THE MACHINE
Ø When transporting the machine, always use the carrying handle.
Ø Ensure the drilling head is at the lowest position.
Ø DO NOT transport the machine with cutters or bits in the tool holder.
Ø If the coolant bottle is connected, ensure the valve is in the “off” position or the
coolant has been drained.
Ø If transporting inside a vehicle, it is recommended to transport it on its side so as to
avoid the item falling over.
Ø If possible, transport in a case.
Ø DO NOT carry the machine by the cord.
Ø DO NOT allow the cord or plug to drag along the floor when transporting.
RUNNING THE MACHINE
Ø Do all pre-operational and operational safety checks from Chapter 1.
Ø Consider your security and stability as well as the orientation of the machine in the
work area.
o Consider the work surface material, condition, strength, density and rigidity.
These factors directly affect the tools magnetic adhesion. Magnetic adhesion
diminishes with thinner material and rough surface. Full magnetic spec’d
adhesion is considered on 1” material. When using on material 3/8” or less,
the drill should be mechanically clamped to the work-piece.
Ø After placing the machine in work area, connect the safety chain.
o The safety chain should attach to the machine (preferably through the
carrying handle) as well as attached to the work area in such a manner that
prevents the machine from detaching or falling from the work area in the
event of magnetic deactivation or lost adhesion.
Ø Ensure the feed handle is securely attached to the feed spindle.

Ø Ensure the work surface and bottom of magnet are free of debris, oil, etc.
Ø Select and set up oiling method or cutting pastes.
o If drilling overhead or horizontal use cutting paste liberally applied to the
cutting bit.
Ø If using the machine horizontally with the oil bottle, connect bottle to the side of the
machine using the two set screws located on the drill frame.
o Connect the oil bottle tube into the side of the tool holder by firmly pressing
in the hose.
§ To remove the hose later, press in the plastic piece around the hose
towards the tool holder while simultaneously pulling the plastic hose
away from the tool holder.
o Make sure the oil bottle valve is in the off position.
§ This is generally at a 90 degree angle from the valve hose.
o Fill the oil bottle with cutting fluid.
Ø Select appropriate size annular cutter or Weldon type twist drill bit.
o The ¾” Weldon shank uses two Allen head bolts. The annular cutters will go
in the shank and be secured on the two flat sides by the two Allen head
screws. See next section below for more specifics on using annular cutters.
Ø Plug the machine into power source.
o Form a loose knot in the power cord close to the plug connection to prevent
cutting fluid from running down the cord and into the power receptacle.
Ø Engage the magnet by pressing the magnet on/off switch on the back of the machine.
o Check that the machine is firmly attached to the work area.
Ø Turn feed handle raising the cutter until the bit is above the work surface.
Ø Open the oil bottle valve to allow oil to come out to the work surface.
o You may have to gently squeeze or shake the bottle to get the oil to start
flowing.
Ø Turn the machine on.
o Start the machine by pressing the green “on” switch. Stop the machine by
pressing the red “off” switch.
Ø Very slowly engage the cutting bit with the material surface by lightly engaging the
hand crank down towards the material.
Ø After about 1/16” of cutting has been achieved in the work surface, slightly more
force can be applied. This will be the normal amount of force the rest of the hole.
TYP- 28A MAG DRILL

o NOTE: Do not force the hole. Let the machine do most of the work.
Excessive physical effort should be avoided as it can cause damage to the
machine or the user.
o If the unit jams in a hole, stop the drill immediately to prevent injury.
Disconnect the drill from the power supply and loosen the cutter by turning
drill spindle counterclockwise. Never attempt to free cutter by starting motor!
Ø Make sure to keep the cutting material adequately lubricated.
Ø Ease up on feed pressure as the cutter starts breaking through the backside of the
material.
o Be mindful that the metal cutting slug can eject at a rapid rate, so be sure all
is clear on the output side of this slug to prevent injury to persons or
property.
Ø Finish drilling the hole.
Ø Turn the motor off and disconnect power once the drill is safely back up in the non-
drilling position.
o Remove metal chips wrapped around cutter and tool holder. Use a leather
glove or pliers as these metal pieces can be sharp.
Ø Disconnect safety chain and move the drill to a new drilling location.
INSTALLING ANNULAR CUTTERS
Ø WARNING: Annular cutters are extremely sharp and should only be handled with a
thick glove so as not to cut the user during installation or removal.
Ø Check that the cutters are sharp and not damaged.
o Annular cutters that are dull or damaged should not be used.
Ø Make certain the machine is unplugged from power.
Ø Raise the tool holder to ensure ample room to install the cutter.
Ø Insert the annular cutter into the ¾” adapter.
Ø Align the two “flat” sides of the annular cutter with the flat sides of the adapter.
o CAUTION: Make certain the hex screw is seated into the flat side and not
simply on the round side of the cutter shank.
Ø Tighten one of the hex screws while slowly rotating the cutter forward and
backwards.
o Continue to tighten the screw until fully tightened.
Ø Tighten the 2nd hex screw.
Ø The annular cutter is ready to use.

Troubleshooting
Note
SERVICING SHOULD ONLY BE DONE BY A QUALIFIED TECHNICIAN.
DON’T FORGET TO UNPLUG POWER TO UNIT PRIOR TO SERVICE!
PROBLEM
SOLUTION
Motor does not turn on.
1) Check external power source (extension cord, breaker, etc).
2) Loose internal wire. Check and secure if necessary.
3) Motor brushes defective. Replace if necessary.
4) Check to ensure the motor on/off switch is operable. Replace if
necessary.
Excessive sparking
when motor is running.
1) This may indicate the presence of debris in the motor or worn out
carbon brushes. Check the brushes for unusual wear and replace
if necessary. Clean out the internal motor armature if necessary.
2) Armature has a rough edge. Inspect and replace if necessary.
Magnetic does not hold
to work area.
1) Work surface thickness is too small. A minimum of 3/8” (10mm)
continuous ferrous steel must be used for magnetic adhesion.
CAUTION: These drills do not work on sheet metal!
2) Entire magnet base is not on the work surface.
3) Voltage is low at the machine. Check voltage.
4) There is debris or excess material between the work area and the
magnetic base. Clean work area surface.
Hole is not cutting.
1) Cutter is dull. Sharpen or replace.
2) Work area material is not appropriate for cutter type. High carbon
type steels require special cutting bits (tungsten carbide tip, etc).
