The G1 High Speed Drill has a variable operating speed of 10,000 to 80,000rpm and offers a power output 30% higher than existing Anspach high speed drills (XMax and eMax2 Plus systems) whilst operating at minimal sound levels. It has a small, lightweight handpiece to minimize hand fatigue (Fig 2), minimal start-up kick and low vibration for increased cutting precision and an integrated air cooling system. The drill is versatile with a wide range of dissection tools including craniotomes, burrs, and straight or angled attachments (Fig 3). The coupling mechanism is simplified (place and lock attachments and push to lock dissection tools) for greater ease of use/effortless assembly. Other features include a new irrigation tube, a hose swivel elbow and increased reliability.
