Dormer 5966887 | 8.40mm Drill Size x 8.40mm Shank x 37.00mm Flute Length x 79.00mm OAL x 135 Degree Point Angle Bright/TiN Coated HSS A022 Screw Machine Length Drill Bit

A022 stub drills are very versatile and are suitable for a wide variety of hand held and machine applications. They are manufactured from premium high speed steel and can be used for drilling a number of different materials including steels, stainless steels and aluminium. With a titanium nitride coating, you get better performance when drilling harder materials and a longer tool life. The specially designed 135 Degree split point is a great aid to self-centering when drilling by hand-so no more wandering all over the surface of the workpiece-and you also get a more accurate hole with a better quality of finish.
