Compliance and Restrictions
Country Of Origin
Chamfer a drilled hole to ensure that fasteners install flush with the surface of the workpiece using these countersinks. Chamfered holes are wider at the top, helping to ensure that the fastener is flush with the workpiece. They can also help prevent material from swelling when a fastener is installed and tightened down. Countersinks can also be used to debur holes for a neat appearance.
Solid carbide countersinks provide good wear resistance when drilling into the toughest materials, such as cast iron, nonferrous alloys, and glass, but they require rigid tool setups because they are brittle.
