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.
5. Start the tool. After drill-
ing to about the depth
of the core bit teeth,
remove the centre 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,
in forward to loosen the core bit from the adapter.
6. Reinstall the core bit and con-
tinue drilling. Dust and debris
will fall through the hole and
optimize the cutting ability of
the bit.
7. For core bits, once the maximum
core bit depth is drilled, the core
must be broken and removed.

4. Press the centring bit

tool firmly and pull the
trigger.
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 25 mm (1") 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.
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 25 mm (1") of drilling. If
necessary, vacuum dust and
debris from the cut and
surrounding area.
