Countersinks

Available4 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.
Primary Material Application

General Purpose Carbide 3-Flute Countersinks

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.
