5/16" Titanium Jobber Drill Bit, 1/4" Hex Impact Shank

A titanium-coated M2 high-speed steel jobber drill built for impact drivers. The 1/4" hex shank locks straight into an impact driver or quick-change chuck, so there is no chuck to tighten and nothing to slip under load. The 135° split point bites on contact, and the TiN coating keeps the cutting edge cooler in steel, stainless and cast iron.
