Dormer 5973254 | 8.50mm Drill Size x 8.50mm Shank x 265.00mm Flute Length x 390.00mm OAL x 130 Degree Point Angle Bright Coated HSS-E A978 Extra Long Drill Bit

The A978 extra long series drills come in a range of metric diameters from 3.00mm to 10.00mm. Part of Dormer's PFX range of drills, the A978 drills have a specially designed parabolic flute which means you can even drill extra deep holes in a single pass. These extra long series drills are recommended for drilling extra deep holes and for applications where a very long reach is needed. They are made from premium High Speed cobalt and are suitable for drilling a wide range of materials including steels, aluminium and stainless steels, whilst the bright finish ensures workpiece material does not stick to the cutting edge, so giving you a cleaner, more accurate hole. The 130 Degree point means the drill will not skid over the surface of the workpiece and also less force is needed to drill a hole.
