Bordo Drill Bit HSS Cobalt Range

Bordo's HSS Cobalt Drill Bits are manufactured from HSS-Co5 steel containing 5% Cobalt. The cobalt significantly increases heat resistance and allows the drill bit to run at higher temperatures without losing its temper (hardness). Cobalt drills provide increased performance and tool life when machining tough steels. Available in metric and imperial sizes.

Ideal for drilling stainless steel and high tensile steel.
