TiN Coated Drill Bit - 2 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... 1/2" Mill Diameter 0.5000" Diameter 4.5" Flute Length 6" Overall Length Solid Carbide TiN Coated 118° Point Angle 2 Pcs
