Recommended for use in difficult materials and applications, the A777 drill from Dormer has a 135 degree split point which helps to self-center the drill and reduces the amount of force needed to drill the hole, whilst the bronze oxide finish helps stop work piece material from sticking to the cutting edge of the drill.

The A777 is made from premium high speed cobalt material which means it can be used for drilling hard materials, including tool steels.

Producing more accurate sized holes with a better finish, the A777 drill really is a great performer.
