Product Description

Countersinks are tools used for cutting angled holes or countersinks in a workpiece. Countersinks have fluted designs and are used to make clean cuts in hardwood, metal, plywood, and plastic. Countersinks are fashioned to a wide range of engagement angles (60° , 82° , 90° , 100° , 110° , 120° , 130° , 140° , etc. ), and to either metric or inch size.

Countersinks are available in a wide range of materials, from general application uses to products used to cut into very hard surfaces. The most commonly used materials for countersink are high speed steel, cobalt steel, carbide and carbide tips. High-speed steel is a cost-efficient cutter material. It is used for general application metal machining. Cobalt steel tools are somewhat harder than high-speed steel and are often used for cutting stainless steel and other alloys. Carbide grades are much harder than high-speed steel, and therefore last longer and wear less. Several coatings are available to lengthen cutter life. This classification includes solid carbide and carbide-tipped countersinks. Special specification countersink on request.
