DANGER! To reduce the risk
of injury, always keep hands,
gloves, rags, clothing, etc. away
from moving parts and chips.
Do not try to remove chips while
the cutter is rotating. Chips are
sharp and can pull objects into
moving parts.
• Always use safety chain. Mounting can release.
• DANGER! T o reduce the risk of injury , always keep
hands, gloves, rags, clothing, etc. away from moving parts and chips. Do not try to remove chips while
the cutter is rotating. Chips are sharp and can pull
objects into moving parts.
• Clean the surface before attaching the drill
stand to the work surface. Paint, rust, scale, or
uneven surfaces decrease the holding strength of
the magnet. Chips, burrs, dirt and other foreign
matter on the surface of the magnet base will also
decrease holding power.
• Do not attach magnetic base to nonmagnetic
grades of stainless steel. The magnet base WILL
NOT hold. The permanent magnetic drill attaches
magnetically to 1/4" or thicker ferrous stock. Do not
use on stock less than 1/4".
* Requires use of 1/2" drill chuck adapter, see "Accessories."
• Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of fl ammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause you
to lose control.
• 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. Unmodifi ed plugs and matching outlets will
reduce risk of electric shock.
• 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.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the
risk of electric shock.
• 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.
• 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.
• If operating a power tool in a damp location is
unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of an GFCI
reduces the risk of electric shock.
• 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 infl uence of drugs, alcohol or medication. A
moment of inattention while operating power tools
may result in serious personal injury.
• Use personal protective equipment. Always
wear eye protection. Protective equipment such
as a dust mask, non-skid safety shoes, hard hat or
hearing protection used for appropriate conditions
will reduce personal injuries.
• Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to power source and/or battery pack, picking
up or carrying the tool. Carrying power tools with
your fi nger on the switch or energizing power tools
that have the switch on invites accidents.
• 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.
• Do not overreach. Keep proper footing and bal-
ance at all times. This enables better control of the
power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or
jewelry. Keep your hair and clothing away from
moving parts. Loose clothes, jewelry or long hair
can be caught in moving parts.
• If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
dust collection can reduce dust-related hazards.
• Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore tool safety principles. A careless action can
cause severe injury within a fraction of a second.
• 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.
• 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.
• Disconnect the plug from the power source and/
or remove the battery pack, if detachable, from
the power tool before making any adjustments,
changing accessories, or storing power tools.
Such preventive safety measures reduce the risk
of starting the power tool accidentally.
• Store idle power tools out of the reach of children and do not allow persons unfamiliar with
the power tool or these instructions to operate
the power tool. Power tools are dangerous in the
hands of untrained users.
• Maintain power tools and accessories. 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.
• Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
• Use the power tool, accessories and tool bits
etc. in accordance with these instructions, 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.
• Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles
and grasping surfaces do not allow for safe handling
and control of the tool in unexpected situations.
• Recharge only with the charger specifi ed by the
manufacturer. A charger that is suitable for one
type of battery pack may create a risk of fi re when
used with another battery pack.
• Use power tools only with specifi cally desig-
nated battery packs. Use of any other battery
packs may create a risk of injury and fi re.
• When battery pack is not in use, keep it away
from other metal objects, like paper clips, coins,
keys, nails, screws or other small metal objects,
that can make a connection from one terminal
to another. Shorting the battery terminals together
may cause burns or a fi re.
• Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact accidentally occurs, fl ush with water. If liquid con-
tacts eyes, additionally seek medical help. Liquid
ejected from the battery may cause irritation or burns.
• Do not use a battery pack or tool that is damaged or modifi ed. Damaged or modifi ed batteries
may exhibit unpredictable behavior resulting in fi re,
explosion or risk of injury.
• Do not expose a battery pack or tool to fi re
or excessive temperature. Exposure to fi re or
temperature above 265°F (130°C) may cause
explosion.
• Follow all charging instructions and do not
charge the battery pack or tool outside the
temperature range specifi ed in the instructions.
Charging improperly or at temperatures outside
the specifi ed range may damage the battery and
increase the risk of
fi re.
• Have your power tool serviced by a qualifi ed
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
• Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
• Hold power tool by insulated gripping surfaces,
when performing an operation where the cutting
accessory may contact hidden wiring. Cutting
accessory contacting a “live” wire may make exposed
metal parts of the power tool “live” and could give
the operator an electric shock.
• Safety Strap
• Do not use near acids or bleaching agents.
• Do not use for overhead lifting.
• Do not use strap if webbing is cut.
• Webbing must be protected from sharp edges.
• All hardware must be in line with direction of
pull for rated capacity.
• Maintain labels and nameplates. These carry
important information. If unreadable or missing,
contact a MILWAUKEE service facility for a free
replacement.
• 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
specially designed to fi lter out microscopic particles.

FUNCTIONAL DESCRIPTION
Typical Operation
1. Check the work surface to make sure it is clean
and free of foreign materials.
Paint, rust, scale or uneven surfaces decrease
the holding strength of the magnet. Chips, burrs,
dirt and other foreign materials on the surface
of the magnetic base will also decrease holding
power. Use a smooth, fl at fi le to keep the magnet
clean and free of nicks.
The drill attaches magnetically to 1/4" or
thicker ferrous stock. Do not use on stock
less than 1/4". The magnetic base WILL NOT
hold on nonmagnetic grades of stainless steel.
WARNING Do not use cutting fl uid
in an overhead or any other position that
allows cutting fl uid to enter motor or switch
enclosure.
6. Insert battery pack.
7. With the on(I) / off(O) switch in the off(O) position, turn the cutting fl uid bottle valve to the
on (downward) position. Cutting fl uid will be
released as the center pin contacts the work
surface.
Failure to lubricate properly will cause cutter
damage. The use of HAWG WASH® cutting fl uid
is recommended for long life of these cutters.
The operator is responsible for the application
of lubricants other than HAWG WASH® cutting
fl uid.
In overhead or vertical cutting applications, do
not use cutting fl uids. Use only lubricant pastes
or sprays recommended for high speed cutting.
Do not allow lubricant pastes and sprays to enter
tool.
WARNING T o reduce the risk of injury ,
do not hold workpiece by hand.
3. Select High Speed or Low Speed , depending on your application.

WARNING Excessive force on the feed
handle will break magnet free.
9. Even large bits only require a small amount of
pressure on the feed handle.
When feeding the cutter into the material, apply
only enough force to produce a curled chip. Applying too little force will result in small broken
chips and increased cutting time. Applying too
much force will cause overheating of the cutter
resulting in short cutter life. Overheating of the
cutter can be noticed when cutter and chips
turn brown or blue. Excessive force can cause
the cutter to slow down to a point where cutting
time will increase. The use of cutting lubricants
will reduce cutting heat and increase cutter life
Use less feed pressure when slotting or notch-
ing because there is less support for the cutting
edges in these situations.
10. Keep constant pressure throughout the entire
operation to prevent chips and burrs from falling
under the cutting edges. Cutting debris under
the cutter can make cutting diffi cult or impos-
sible.
11. When the cut is complete, withdraw the cutter
while the spindle is still rotating.
12. Stop the drill motor by pushing in the on(I) / off(O)
switch.
13. When the spindle has stopped rotating, use
a pliers to remove cutting debris and chips
from the cutter and spindle. Use care to avoid
damaging the cutter teeth.
14.
The center pin is spring loaded. Provide protec-
tion from ejected slug for people and property
below cutting area.
15. Firmly grip the tool and rotate the magnet knob
to disengaging the magnet.
16. When drilling on pipe, use the accessory pipe
adaptor 48-10-0130 and the safety strap.
