Substantially longer cutting life
Nitro-carburized flute has increased Rockwell hardness & will out perform cobalt
Cuts harder material
The flatter point takes a smaller chip. This allows drilling Into material with hardness over 30 on Rockwell scale.
Stops drill walking
The split point design gives accurate starting without the use of a center point.
Holds tighter holes
Split point design is self centering. This limits the normal oversize drilling characteristics.
