22 products
Countersinks expand the top of an existing hole in a workpiece to ensure screws install flush with the surface of the workpiece. This helps prevent the workpiece material from swelling when a screw is installed in the hole and tightened down in metalworking applications. Countersinks can also be used to debur holes for a smooth finish.

Anti-vibration Cobalt Steel Zero-Flute Countersinks
Cobalt steel zero-flute countersinks provide good wear resistance when machining hard materials at high speeds. Zero-flute countersinks have a single flute that passes through the center of the countersink. This minimizes vibration and chatter during use and prevents chips from sticking to the tool. Zero-flute countersinks leave smooth, clean edges on holes and are used to expand the top of an existing hole in a workpiece to ensure screws install flush with the surface of the workpiece. They are commonly used for installing aluminum frame storefronts, glass and window design, and architectural metalworking applications.

Smooth-Finish Carbide 6-Flute Countersinks
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.
