stud is used, or a cen-
ter pin and guide plate
are not available, use
a template or notched
board to start the hole.
5. Start the tool. After drill-
ing to about the depth
of the core bit teeth,
remove the center pin
and guide plate from
the core bit (not nece-
sary for LHS system).
Resume drilling.
6. To change the core bit, hold the tool upwards,
pointing it away from your body, and run it briefly
in forward to loosen the core bit from the adapter.
NOTE: To make deeper holes, remove the core bit,
break and remove the core, then resume drilling.
When drilling long or deep holes, after each inch
of penetration pull the bit partially out of the hole
while the tool is running, to help clear dust from
the bit flutes. Dust can clog the bit flutes and can
make the bit bind in the hole. If this occurs, stop
the tool, free the bit and begin again.
Drilling Large Diameter Holes
with Core Bits
When drilling holes with large diameter core bits,
dust may build up in the cut and can cause the tool
to stall, bind, or cut slowly. By creating an opening
for the dust to escape, drilling time, bit stress, and
tool stress can be reduced.
1. Start the cut as normal.
2. Once the bit is firmly established in
the cut (about 1/4" deep), remove
the bit from the cut.
3. Remove the bit from the tool.
4. Install a standard fluted bit, ap-
proximately 7/8" in diameter, onto
the tool.
5. Drill a perpendicular hole through
the kerf of the large hole.
• Depending on the location of the
work, the hole should either break
through the other side of the hole/
floor or extend 4"-5" past the end

it out and continue drilling.
• If drilling through a wall, the hole
for dust should be drilled on the
lowest part of the large hole
kerf as the dust will fall there
when drilling and can be evac-
uated more easily.
6. Reinstall the core bit and con-
tinue drilling. Dust and debris

the hole.
NOTE: If unable to drill a hole
in the kerf, pull back on the bit
with the hammer running. This
will remove some of the dust
and debris from the cut. Repeat
this for every inch of drilling. If
necessary, vacuum dust and
debris from the cut and sur-
rounding area.
7. For core bits, once the maximum
core bit depth is drilled, the core
must be broken and removed.
• Install a chisel bit.
• Place the chisel into the hole
kerf.
• Chisel down into the kerf at
several points until the core is loose or broken.
• Remove the core and vacuum/remove any remain-
ing dust and debris.
• Install the core bit and continue the cut.
WARNING
• Always use the "hammering-only" setting to
set the anchor. Never use the "hammering-
with-rotation" setting to set the anchor.
• Never switch the tool to "hammering-with-
rotation" until after the anchor has been set
and the tooth anchor chuck has been removed
from the anchor.
Setting Self-Drilling Anchors
MILWAUKEE Tooth Anchor Chucks require a "B"
taper adapter.
1. Place the proper size tooth anchor chuck into the
"B" taper adapter. Then insert the "B" taper adapter
into the tool and lock it into place as described.
See "Installing Bits and Chisels".
2. Insert the anchor into
the tooth anchor chuck.
