Cobalt-alloyed HSS drill bits for stainless steel and tougher materials where standard HSS wears quickly.
HSS Cobalt Drill Bits contain cobalt in the steel for higher red hardness and heat resistance. They hold their cutting edge longer when drilling stainless steel, alloy steels and other difficult materials, making them a good upgrade for production and maintenance teams.

Match the diameter, thread or profile to your drawing. For taps, use the correct tapping drill size listed in the size table.
Use cutting speeds suited to the material. Harder materials need lower speeds; excess speed shortens tool life.
Cutting oil or coolant reduces heat, improves finish and extends tool life when cutting steel.
Clamp the workpiece securely and wear safety glasses and gloves. Replace worn or chipped tools.
