Features

·Manufactured to NAS 907C specification.
·Nitro-carburized flute has an increased Rockwell hardness.
·Rich amber color.

Applications

·Outperforms cobalt drills in work hardening stainless steel applications.

Benefits

·Much tougher than cobalt steel.
·Thin web design will penetrate the work hardening (series 300, except for 303 which is free machining) stainless steel fast enough to continually cut beneath the chip which is hardening from deformation.
·135° split point design stops drill walking, holds tighter hole size and takes a smaller chip resulting in less heat.
·Low temperature stress relief improves lubricity and toughness.
