HSS-Co Spiral Flute

About

HSS‑Co Spiral Flute HSS‑Co Spiral Flute cutters are high‑speed steel drill bits alloyed with cobalt, built to drill through tough metals — including stainless steel, alloyed steel and heat-treated materials — while resisting heat and wear. The spiral‑flute geometry improves chip evacuation and coolant flow, reducing clogging and overheating, which results in cleaner, more precise holes and longer tool life. Ideal for metalworking, fabrication, mechanical and industrial drilling tasks , HSS‑Co Spiral Flute bits offer durability, efficiency and reliability where standard bits may fail.
