Substantially longer cutting life - The nitro-carburized flute has an increased Rockwell hardness.
Cuts harder materials - The flatter point takes a smaller chip. More torque is directed to a smaller area. This allows drilling into materials with hardness of over 30 on the Rockwell "C" scale.
Stops drill walking - The split point design gives accurate starting without the use of a center punch.
Holds tighter hole size - The split point design is self centering. This limits the normal oversize drilling characteristics.
Runs cooler, uses less torque - 135° point takes a smaller chip resulting in less heat. Friction is reduced by amber gold surface treatment.
Stops chuck slippage - Flats on drill shanks allow easy positive chuck grip.
