4CJX9 Countersinks

Bulk orders will be discounted, please contact us.

Solid carbide countersinks provide excellent wear resistance when machining the toughest materials, such as cast iron and stainless steel. Six-flute countersinks provide fast material removal and leave a smooth finish as they expand the top of an existing hole in a workpiece to ensure screws install flush with the surface of the workpiece. They remove more material with each revolution and typically provide more wear resistance than countersinks with fewer flutes.
