Drill Bit Sets – High Speed Steel Bright finish – enhances lubricity. Good choice for use in nonferrous and low carbon steel. Allows for alternate surface treatments to be applied to suit specific applications.

Black oxide/steam oxide – for ferrous materials, improves lubricity and increases wear resistance, improving chip flow – enhances coolant absorption.

Black and gold – for ferrous materials, increased lubricity and longer tool life.

Straw finish – easily identifies cobalt tooling with no other application benefits. TiN (titanium nitride) – for ferrous and non-metallic materials; free-ma- chining steels and irons, high tensile steels, tough machining steels, plastics and hard rubber. The hard, smooth finish increases tool life, improves finish and allows higher speeds. WLT01E606 WLT01E618
