2. Pull the trigger, applying just enough pressure on the
hammer to keep it from bouncing excessively or "rising"
off the bit.
Recommendations for Hammerdrilling
•
Too much force will cause slower drilling speeds,
overheating, and a lower drilling rate.
•
A smooth even flow of material indicates the proper
drilling rate.
•
Drill straight, keeping the bit at a right angle to the work.
Do not exert side pressure on the bit when drillling as
this will cause clogging of the bit flutes and a slower
drilling speed.
•
When drilling deep holes, if the hammer speed starts to
drop off, pull the bit partially out of the hole with tool still
running to help clear debris from the hole.
