Dormer R4639.2 | 0.3622″ Diameter x 4.0551″ OAL TiAlN Coated Jobber Length Drill Bit – All Industrial Tool Supply

Description

Part of Dormer’s solid carbide range of drills, manufactured from premium carbide, R463 drills are specifically designed for drilling stainless steels and other heat resistant super alloys and will produce high quality and accurate holes (H9 hole tolerance) even at high speeds and feeds. The drills have a 140 Degree 4-facet split point which reduces the push force required and also helps with self-centering. With a titanium aluminium nitride coating, you can expect a longer tool life and improved performance when drilling harder materials. R463 carbide drills have a special CTW flute design (Continuously Thinned Web) which provides increased strength and, along with the coolant feed, allows the drill to operate at higher cutting speeds and feeds.
