Ensure the drill has a resistance free path of insertion by pumping the drill in-and-out of the drill guide prior to drilling. Each drill should be advanced as far as possible through the master cylinder prior to initiating drilling. Use short, light strokes to progressively advance the drills to depth with minimal pressure on the drills. Profuse irrigation throughout the drilling sequence is necessary to provide lubrication and prevent overheating. Use an in-and-out pumping action (Figure 1) to help clear flutes of any bone debris. Drills should not be completely removed from master cylinders during pumping. When finally removing drills from master cylinders the drill should not be rotating. Avoid applying lateral pressure to the master cylinder by ensuring the drill path is in line with the master cylinder.
