Dormer 5980431 | 11.50mm Drill Size x 11.50mm Shank x 94.00mm Flute Length x 142.00mm OAL x 130 Degree Point Angle TiN Coated HM R510 Jobber Length Drill Bit

R510 ADX jobber drills from Dormer are manufactured from premium carbide and can be used for drilling a number of materials including steels, cast iron and aluminium. With a 130 Degree point to help with self-centering and reduce the push force, the drills are capable of producing high quality and accurate holes (H8 hole tolerance) even at high speeds and feeds. With a titanium nitride coating to extend the life of the drill and improve performance when drilling harder materials, R510 carbide drills have a convex cutting edge which helps break chips for easier removal, allowing increased speeds and feeds.
