Tool Selector


The range consists of two types: a countersinking tool with three cutting edges and a countersinking tool with only one cutting edge. Each design is available in two versions with a countersink diameter range from 3.0 – 25.0 mm and another from 4.0 – 45.0 mm. The HEULE countersinking tools are available with countersinking angles of 60° and 90°.

Should no standard tool solution be available for your application, HEULE can make a detailed application analysis. The result will be an application-specific solution. 


The GH-K has an alloy heat-treated steel tool body and integrated internal coolant. The blades are made of coated carbide and can be resharpened or replaced. These cutting edges extend almost to the countersinking tool tip, providing a wide countersink diameter range.

Process steps description

The HEULE countersinking tool enables chatter-free countersinking and circular milling. The tool's internal coolant supply delivers the coolant directly to the cutting edge. The three carbide cutting edges and three insert seats in the tool body are manufactured to extremely tight tolerances. This means that high cutting parameters allow for the optimal production of chatter-free countersinks on the bores and chamfers on the edges of workpieces.
