The A520 short drill is part of Dormer’s ADX range of drills and is designed for high performance drilling.
It has a 130 degree thinned point which both helps with self-centering, so the hole is exactly where you want it, and also means less force is needed to drive the drill through the workpiece material.
The titanium nitride coating gives you a better tool life and also improves performance when drilling harder materials.
The drill has specially shaped cutting edges which break the workpiece material into smaller chips which are more easily removed from the hole.
This, in turn, means you can use higher speeds and feeds to drill the hole – increasing your productivity.
The A520 high performance drill is capable of producing good quality and accurate holes (to H9 hole tolerance) even at high speeds and feeds
