Item #: 00647768Brand: Triumph Twist DrillModel #: 012828 Features and Benefits 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.
