TiN Coated Drill Bit - 12 pcs High speed steel (HSS) provides good wear resistance and can be used in general purpose applications for both ferrous and nonferrous materials. Titanium Nitride (TiN) is a multi-purpose coating which increases chip flow in softer materials. The heat and hardness resistance allows the tool to run at higher speeds than uncoated tools. Spiral flutes are constructed with a higher flute angle to remove chips more easily. Features include... 1/16" Mill Diameter 0.0625" Diameter 7/8" Flute Length 1 1/2" Overall Length Solid Carbide TiN Coated 118° Point Angle 12 pcs
