Hammer drilling operation
Position the bit
at
the location for the hole,
then pull the trigger.
Do not force the tool. Light pressure
gives
best results. Keep the tool in position and
prevent
it
from slipping away from the
hole.
Do not apply more pressure when the hole
becomes clogged with chips or particles.
Instead, run the tool
at
an idel, then re-
move from the hole.
By
repeating this
several times, the hole will be cleaned out.

Drilling in wood
When drilling in wood, best results are obtained with wood drills equipped with
a
guide
screw. The guide screw makes drilling easier by pulling the bit into the workpiece.

Drilling in metal
To prevent the bit from slipping when starting
a
hole, make an indentation with
a
center-
punch and hammer
at
the point to
be
drilled. Place the point of the bit in the indenta-
tion and start drilling.
Use
a
cutting lubricant when drilling metals. The exceptions are iron and brass which
should be drilled dry.
