Countersink drill bits set HSS M35 Co 6pcs (6.3-20.5mm)

The HCD060CO Countersink Drill Bit Set is a professional tool kit designed for precise chamfering, deburring and countersinking of screw and bolt heads. Manufactured from premium HSS M35 high-speed steel with 5% cobalt, these countersinks provide exceptional wear resistance, heat resistance and long service life.

The cobalt alloy enables efficient machining of carbon steel, stainless steel, alloy steels, cast iron and non-ferrous metals. Sharp cutting edges produce smooth, accurate chamfers while reducing burr formation for a clean professional finish.
