Successful drilling involves three elements:
• Forming a chip
• Accommodating a chip
• Evacuating a chip
Aircraft Extension Drills ...................
Extra Length Drills ............................ 25
Drill Geometry
• Use the shortest drill possible
• Use a split point drill if possible. Split points
begin removing material on contact and
drill more efficiently
