HSS-Co (Cobalt) Drill Bits

HSS-Co Cobalt Drill Bits are high-performance metal-cutting drills designed for demanding drilling applications in tough and heat-resistant materials.

Manufactured from cobalt-alloyed high-speed steel, HSS-Co drill bits offer improved heat resistance, wear resistance and cutting performance compared with standard HSS drills, making them particularly suitable for harder metals and more intensive drilling work.

Our range includes professional PFERD cobalt drill bits for drilling stainless steel (INOX), alloy steel, steel and other difficult-to-machine metals, with different diameters and specifications available for workshop, fabrication and engineering applications.

HSS-Co drill bits are ideal where standard HSS drills may struggle with heat build-up or rapid wear, helping provide reliable cutting performance, good hole accuracy and longer tool life in demanding conditions.
