Core bits are useful for drilling larger holes for
conduit and pipe. MILWAUKEE Thin Wall Core
Bits have heat-treated steel bodies with durable
carbide tips. These core bits are specially designed
for fast, accurate drilling with combined hammering
and rotary action.
1. Clean and lubricate the
threads on the adapter
and core bit to make later
removal easier. Screw the
threaded end of the adapter
into the rear of the core bit.
For core bits 1- 1/4"
and larger, push the guide
plate onto the pointed end of
the center pin. Insert the center
pin and guide plate assembly
into the core bit. Be sure the
small end of the center pin is
securely placed into the hole
in the center of the core bit.
2. Insert the adapter into the nose
of the tool as described in “In-
stalling Bits”. Set the hammer/
drill shift knob to hammering
with rotation.
3. Press the center pin firmly
against your center mark, hold
the tool rmly and pull the trigger.
If a center pin and guide
plate are not available, use a template or notched
board to start the hole.
4. After drilling to about the depth of the core bit
teeth, remove the center pin and guide plate from
the core bit. Resume drilling.
5. To change the core bit, hold the tool upwards,
pointing it away from your body, and run it briey
in forward to loosen the core bit from the adapter.
To make holes deeper than 3", remove the
core bit, break and remove the core. Resume drilling.

Always allow the motor to come to a complete stop
before using the control switch.
For (clockwise) rotation, push the control
switch to the left side of the tool. Check the direction
of rotation before use.
For (counterclockwise) rotation, push the
control switch to the right side of the tool. Check
direction of rotation before use.
1. To the tool, grasp the handle rmly and pull
the trigger.
2. To the speed, increase or decrease the
pressure on the trigger. The further the trigger
is pulled, the greater the speed.
3. To the tool, release the trigger. Make sure
the tool comes to a complete stop before laying
the tool down.
Position the tool, grasp the handles rmly and pull
the trigger. Always hold the tool securely using
both handles to maintain control. This tool has
been designed to achieve top performance with
only moderate pressure. Let the tool do the work.
If the speed begins to drop off when drilling large
or deep holes, pull the bit partially out of the hole
while the tool is running to help clear dust. Do not
use water to settle the dust since it will clog the bit
utes and tend to make the bit bind in the hole. If
the bit should bind, a built-in, non-adjustable slip
clutch prevents the bit from turning. If this occurs,
stop the tool, free the bit and begin again.
