the
hole, then pull the trigger.
Do not force the tool. Light pressure
gives
best results. Keep the tool in posi-
tion and prevent it from slipping away
from the hole.
* D o
not apply more pressure when the
hole becomes clogged with chips or par-
ticles. Instead, run the tool
a t
an idle,
then remove from the hole.
By
repeating
this several times, the hole will be cleaned
out.

ing over the

the bit up to 14.5 mm (9/16') in diameter.
