Drill Bits

These mechanic length drill bits are made of special hi-molybdenum tool steel. They have a 135° split point to stop the drill from walking. To eliminate drill slippage, there are 3 flats on the shank. These drill bits are heat treated to 2185°F and are nitro-carburized to reduce friction, for a longer life.
