Care and Use of Bits
1.
Be certain the bit fits on the taper of the steel.
2.
Never approach the material with the Hammer Drill
running. Position the Hammer Drill carefully and collar the
hole at reduced throttle. This prevents damage to bit
inserts.
3. Always keep the Hammer Drill fed up to the work.
Insufficient feed pressure will cause the bit to become
loose on the steel and will cause inserts to tear loose.
4. Always maintain alignment between the Hammer Drill and
the hole.
5.
Never allow the hole to become filled with loose cuttings.
Blow the hole frequently.
6.
Never retract the Hammer Drill at full throttle, use part
throttle.
7. Never force or broach the bit into a hole.
8. Don't rough handle steels with bits on.
9. Never run a dull bit.
10. Remove the bit by pulling it from the steel.
Never clamp the bit in vice jaws. The squeeze caused by
clamping will only tighten the bit on the steel.
