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,
approximately 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 of the workpiece
(such as into the dirt below a
concrete slab).
• If dust builds up in the hole,
vacuum it out and continue drill-
ing.
• 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
evacuated more easily.
6. Reinstall the core bit and
continue drilling. Dust and
debris will fall through the
hole and optimize the cutting
ability of the bit.
NOTE
: If unable to drill a hole
in the kerf, pull back on the bit
with the hammer running. This

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 remaining dust
and debris.
• Install the core bit and continue the cut.
WARNING
To reduce the risk of personal in-
jury and damage to the tool or
work:
• 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
1/8"
the tooth anchor
chuck. Set the knob
for hammering only.
Set the anchor on
your mark and ham-
mer until the teeth
have penetrated the
concrete.
3. Set the knob for ham
-
mering with rotation
and drill until the
chuck is 1/8" above
the concrete.
NOTE:
It may be nec-
essary to clean dust
and cuttings from the
anchor several times
while drilling the hole.
4. Remove the anchor
from the hole while the
tool is running. Clean
the dust and cuttings
from the anchor by
pointing it downward
and turning the tool
on and off several times. Clean the dust out of the
hole with a vacuum cleaner or blowout bulb.
5. Place the expansion
plug into the anchor
and insert the anchor
into the hole. Switch
the knob back to ham-
mering only, and ham-
mer the anchor firmly
into the hole.
