WARNING! Read and understand all instruction before operating any drilling system. Failure to
follow all instructions listed below may result in electrical shock, damage to drilling system and even
personal injury.
GENERAL SAFETY INSTRUCTIONS
Work area
1. Keep your working area clean and well lighted. Cluttered benches and working stations causes
accidents as well as dark spaces. Always ensure working stations are clean and well lit.
2. Do not operate power tools in explosive atmosphere, such as in the presence of flammable liquids,
gases or extreme dust. Power tools create sparks that may ignite gases as well as flammable
liquids. Dust may enter the ventilation system causing clogging and causing overheating.
3. Keep bystanders, children and visitors away from moving parts of the power tool. Any distractions
can cause you to loose control of the power tool and an injury could take place.
Electrical Safety
1. Grounded tools must be plugged into an outlet properly installed and grounded in accordance
with all codes and ordinances. Never remove the ground prong or modify the dance plug in any
way. Do not use any adaptor plugs. Check with a qualified electrician if you are in doubt as to
whether the outlet is properly grounded. If tools should electrically malfunction or break down,
grounding provides a low resistance path to carry electricity away from the user.
2. Never carry a tool by the cord or hose and “yanking” the cord or the hose to disconnect it from the
receptacle. Always carry the power tools properly and store in dry and dust free place.
3. Keep cords and hoses away from heat, oil and sharp edges. Damaged cords increase the risk of
electric shock.
4. Don’t expose power tools to rain or wet conditions. Water entering a power tool will increase the risk
of electric shock. When operating a power tool outside, use an outdoor extension cord marked .
W-A. or. W.. These cords are rated for outdoor use and reduce the risk of electric shock.
Personal Safety
1. Stay alert, watch what you are doing and use common sense when operating a power tool. Do not
use tool while tired or under the influence of drugs, alcohol, or medication. A moment of
inattention while operating power tools may result in serious personal injury.
2. Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing,
and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving
parts.
3. Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with your finger on
the switch or plugging in tools that have the switch on invites accidents.
4. Remove adjusting keys or switches before turning the tool on. A wrench or a key that is left attached

4
to a rotating part of the tool may result in personal injury.
5. Do not overreach. Keep a proper footing and balance at all times. Proper footing and balance
enables better control of the tool in unexpected situations.
6. Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hardhat, or
hearing protection must be used for appropriate conditions.
Tool use and care
1. Use clamps or other practical way to secure and support the work piece to a stable platform.
Holding the work by hand or against your body is unstable and may lead to loss of control.
2. Do not force tool. Use the correct tool for your application. The correct tool will do the job better and
safer at the rate for which it is designed.
3. Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with the switch
is dangerous and must be repaired.
4. Disconnect the plug from the power source before making any adjustments, changing accessories,
or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.
Store idle ling tools out of reach of children and other untrained persons. Tools are dangerous in the
hands of untrained users.
5. Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools, with sharp
cutting edges are less likely to bind and are easier to control.
6. Check for misalignment or binding of moving parts, breakage of parts, and any other condition
that may affect the tools operation. If damaged, have the tool serviced before using. Poorly
maintained tools cause many accidents.
7. Use only accessories that are recommended by the manufacturer for your model. Accessories that
may be suitable for one tool may become hazardous when used on another tool.
Service
Only qualified repair personnel must perform tool service. Service or maintenance performed by
unqualified personnel could result in a risk of injury.
When servicing tool, use only identical replacement parts. Follow instructions in the Maintenance
section of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a
risk of electric shock or injury.
Symbols used in this manual
IMPORTANT: Some of the following symbols may be used on your tool. Please study them and learn their
meaning. Proper interpretation of these symbols will allow you to operate the tool better and safer.

Terminology used in the manual
1. Warning: This term means that there is a risk of physical harm or death to the operator or people
nearby.
2. Caution: This term means that there is a risk of damage to the machine, cutting tool or other
equipment.
3. Note: These terms offer useful information relating to the operation of the machine or its
maintenance.
SPECIFIC SAFETY RULES AND REGULATIONS
1. Always use safety chain. Mounting can release.
2. The magnet’s adhesion depends on the thickness of the work piece. Always ensure that the work
piece is a minimum of 12mm (7/16 in.) thick. If it is not, then use a piece of steel plate at least12mm thick
and larger than the magnet below the work piece to supplement the magnetic adhesion.
3. Metal chips and other debris will seriously hamper magnetic adhesion. Always ensure that the
magnet is clean and free of rust and scale.
4. Other units used on the same receptacle will cause uneven voltage that could lead to the magnet
releasing. Always use the tool alone on the receptacle.
5. It is hazardous to use the drill upside-down. Do not exceed 90 degrees from horizontal.
6. Avoid the magnet releasing. Ensure that the magnet has properly adhered to the work piece before
beginning drilling.
7. Avoid operating annular cutters without coolant fluid. Always check coolant level before operating.
8. Do not operate with dull or damaged cutting tools. This may overload the motor.
9. Protect the motor. Never allow cutting fluid, water, or other contaminants to enter the motor.
10. Metal chips are often very sharp and hot. Never touch them with bare hands. Clean up with a

magnetic chip collector and a chip hook or other appropriate tool.
CAUTION: NEVER position machine on a work piece between the electrode and the ground of any arc
type welder. Damage to the machine will result, as the welder will ground through the machine’s
ground cable. When drilling stacked work materials, always stop to clear the slug after the first layer is
drilled.
WARNING: Do not operate the machine on a workpiece which is being welded on at the same time. This
may lead to damage to the machine and possible injury.
WARNING:NEVER attempt to use machine with incorrect current or abnormally low voltage. Check
machine nameplate to ensure that correct voltage and Hz are used. When drilling non-ferrous (non-
magnetic) work materials, only use a manufacturer- approved fixture such as a vacuum base adapte.
Magnet Base Duty Cycle
Do not leave the magnet base activated continuously for more than 60 minutes. If the magnet base is
overheated, allow it to cool for 30 minutes before continuing.
This machine is not intended for production-line type use.
CAUTION:Turn the magnet base off when not in use. Leaving the magnet base on continuously will
damage it.
WARNING: For safe magnetic adhesion, the minimum thickness of the workpiece must be at least
10mm.
ASSEMBLY
Coolant tank assembly required. First attach clear tube to the bottom of the coolant tank. To do this, first
loosen the nut and slide nut onto the tube. Then slide tube onto the nipple. Then tighten the nut. Slide tank
hanger over the screw on the upper right hand side of slide and tighten. Finally insert the other end of the
tube into the quick-release connector in the gearbox. Just directly push in to install. (To remove, first firmly
push the red collar of the connector and pull the tube out.) Cutting coolant fluid is always required when
using annular cutters. Open tank cover and fill. Check coolant fluid level often. Keep coolant tap closed when
not in use.
Chip guard must be used. To attach the chip guard, use the supplied butterfly bolts to bolt to the magnet. It
is not necessary to remove guard to clean chips. Simply raise guard to its upper position.
Safety chain must be used. Loop chain around the work piece and feed through the machine’s handle and
clip in place.

MOUNTING ANNULAR CUTTERS
CAUTION: Never use a cutting tool that is larger than the maximum rated capacity of the machine.
1. To insert an annular cutter, first insert the pilot pin into the
cutter. Then slide the cutter into the arbor, align the proper
flat with the locking screw(s) and tighten securely with the
supplied hex wrench.
CAUTION: Ensure that the locking screw is on a flat of the cutter
and not just against the rounded shank.
2. Ensure that the oil feed tap is on and coolant feeds properly by pushing the pilot pin. If it feeds too
quickly or slowly, adjust the tap accordingly. Keep the tap closed when not in use.
OPERATION-GENERAL
WARNING: Always ensure that the magnet is adhered properly to the work piece before beginning
drilling.
NOTE: If mounting to a curved surface beam, mount the machine parallel to the curve in the work
piece.
WARNING: Avoid operating at more than 90 degrees from horizontal. When drilling at such an angle
take precautions to prevent cutting coolant from entering the motor. Paste-type coolant should be
used.
CAUTION: Machine is equipped with a reversing switch. Always ensure that direction of rotation is
correct before operating. Operating in the wrong direction could result in damage to the cutter.
1. First fit tool into arbor and line up with intended center of cut. Then
switch magnet on.
2. Press green motor on button to start motor. Use the crank handle to feed
to work. Always use very light pressure when beginning the cut and just
as the tool is breaking through. The crank handle offers tremendous
leverage; so do not use too much force. Allow the cutting tool to
determine the pace. With experience, the operator will be able to
determine the best pace to feed to the work. There should be some
degree of audible slowing of the motor but not bogging in the cut.
Correct cutting speed with a properly sharp annular cutter will produce
long unbroken chips, which produce a “bird’s” nest. shaped bundle of
chips around the cut.

NOTE: Always ensure that the cutting tool is sharp. A dull cutter typically will have finer and/or choppy
shavings.
WARNING: ALWAYS clear chips when there is too much build-up. Excessive chip build-up could result in
a jammed cutter or other hazardous situation.
WARNING: the slug ejects at end of cut and is very hot. Always provide a method of catching the slug,
where the ejected slug may cause injury to people below.
Note: Lock the slide lock on the side of the machine in the fully raised position when at rest to prevent
the slide from accidentally slamming down - remember to unlock it again before commencing drilling.
CAUTION: Never attempt to cut half-circles or to stitch drill (drill overlapping holes) with a TCT cutter.
This may destroy the cutter.
CAUTION: Never attempt to re enter a half-finished cut if the magnet has been turned off and the
machine shifted in the interim. This may destroy the cutter.
SWIVEL BASE
The swivel base allows the drill to be precisely positioned under difficult
circumstances.
To use: first position the magnet base in the desired position and turn
magnet on.
Loosen the 2 Swivel Lock Tabs, then swivel the machine body into the
desired position. Finally lock both Swivel Lock Tabs.
CHANGING TOOLS & ADAPTORS WITH MT2 SHANK
To insert a tool, turn the tool until the tang lines up and firmly push into
place. It is helpful to tap with a soft-faced mallet to fully engage the taper. If it
is properly in position, one will not be able to pull it back apart by hand. To
remove, slide the ejector drift into the ejector slot and tap with a hammer to
eject the tool.
CAUTION: When removing, take care that the cutting tool does not
crash down and get damaged or injure anyone below.

MT2 ANNULAR CUTTER ADAPTOR
This machine is equipped with a unique annular cutter adaptor system with built-in coolant directly to the
gearbox.
1. To install the annular cutter adaptor, first insert the taper end of the adaptor into the arbor of the
machine as described above.
2. Attach the coolant tank to the slide and ensure that the tube is attached properly.
3. To insert an annular cutter, first insert the pilot pin. Then slide the cutter into the adaptor, align the
proper flat with the locking screw(s) and tighten securely with the supplied hex wrench.
4. Ensure that the oil feed tap is on and coolant feeds properly by pushing
the pilot pin. If it feeds too quickly or slowly, adjust the tap accordingly.
Keep the tap closed when not in use.
GEAR SELECTION
Before drilling select desired gear range by first pushing in on spring-loaded
gear selector slider switch and then sliding selector up for high speed or
down for low speed. (It may be necessary to turn the arbor slightly in order for the gears to mesh properly).
Follow the recommended speed ranges on the cutting speed chart to set the proper speed and gear range.
CAUTION: Ensure that that gears engage fully.
CAUTION: ALWAYS ensure that the machine is fully stopped before attempting to change gears! NEVER
change gears on a running machine!

NOTE: These speeds are general recommendations only. The material should determine actual speeds
and the cutting speed recommended by the cutting tool manufacturer. See the section below
"RECOMMENDED SURFACE SPEEDS" and use the formula to calculate the best RPM.
VARIABLE MOTOR SPEED
The electronic variable motor speed control allows the motor speed to be
lowered for further flexibility for adjusting the cutting speed to suit the size
of cutter and type of material. Simply turn the thumb wheel to raise or lower
the motor speed electronically.

Variable Speed Knob

10
NOTE: whenever possible, it is always preferable to lower the speed by changing the gear rather than
lowering the motor speed. A slower motor speed will have less cooling and somewhat less torque so
always try to keep the motor going as fast as possible. Only lower the motor speed if you have no other
option.
(For example: If you need the RPM at about 300/min, it is much better to use 1st gear at full motor speed than
to use 2nd gear at a lower motor speed.)
AVOID OVERHEATING THE MOTOR
When using the machine at or near maximum capacity with a slow motor speed the motor will be at
maximum stress and very hot. After each cut is finished, ALWAYS cool the motor by running at no load at the
maximum motor speed for a few minutes.
CUTTING SPEEDS
The type of material to be drilled, its hardness and thickness will all greatly affect the recommended cutting
speed. See the chart below for general guidelines for cutting speeds. Use the formula to determine the
recommended RPM for the diameter of annular cutter being used:
RECOMMENDED SURFACE SPEEDS
Note: work materials which have been flame cut will be heat treated in the affected area. These areas
will require much slower cutting speeds.
Work Material Surface Speed MPM (m/min)
Aluminum 60-90
Brass 40-50
Soft Cast Iron 30-50
Hard Cast Iron 15-21
Mild Steel 24-30
High Tensile Steel 6~13
Stainless Steel 3~5
RPM = 318.5 x MPM / cutter diameter (in mm)
For example: if you are drilling mild steel with a 50mm cutter, the recommended MPM would be about 30 m/
min, so the ideal RPM would be:
318.5 x 30/50 =191/min
But if you were drilling high tensile steel, the MPM would be about 6 m/min, so the ideal RPM would be: 318.5
x 6/50 =38/min
