Dormer 6814189 | 12.70mm Diameter x 6.00mm Shank x 77.00mm OAL TiAlN Coated HM P821C Burr

P821C rotary carbide burrs from Dormer are made from premium carbide material for superior performance and extended tool life at high speeds. Tool life is further enhanced thanks to the titanium aluminium nitride coating, which also aids performance at high speeds for longer periods. With a ball nosed cone shape (Shape L) and skip flute geometry, the burrs are designed for de-burring in tight corners. DC geometry breaks chips more easily for better control when de-burring by hand. Completing the main features is the hardened and toughened steel shank, which provides extra strength and rigidity to reduce vibration and make the burrs last longer.
