Bordo 1/8" Long Series HSS Drill Bit Imperial (Clam Shell) - 2500-1/8S

Description

Bordo Long HSS Black Drill Bit Clam Shell (2500) - Imperial

ANSI B94-11.
118° chisel point with 30° helix.
Chisel point is suitable for general purpose drilling.
Black Finish Twist Drills (also called blue finish) achieve their distinctive colour by steam tempering, a thermal process resulting in a porous tool coating.
This surface helps to keep lubricant on the tool, particularly important on the cutting edges, thus reducing friction and cold welding. The result is increased tool life.
Black finish tools are generally recommended for ferrous applications where the oxide layer aids chip flow and heat dissipation.
