Available3 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.

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.

General Purpose Carbide 3-Flute Countersinks
Solid carbide countersinks provide excellent wear resistance when machining the toughest materials, such as cast iron and stainless steel. General purpose 3-flute countersinks are the most common choice for expanding the top of an existing hole in a range of materials to ensure screws install flush with the surface of the workpiece. Three-flute countersinks typically provide better chip clearance and perform better when machining stringy materials than countersinks with more flutes.
