Rules for Drilling

• Spot drill holes.

• Consider using progressively larger drills to make a large hole.

• Peck drill deeper holes.

• Use a canned cycle when possible. If programming using line and rapid moves, be sure to extract the tool completely from the bore before changing tools.

• Use the shortest drill possible to reduce tool chatter and produce a more accurate hole.
