The GH-K tool is a precision inserted countersink tool with three effective cutting edges and large countersink range. The blades are precision ground as a matched set to achieved unmatched countersink finishes. Positive geometry allows for high shear cutting action. Carbide blades are best suited for cast iron, aluminum and other non-ferrous materials and HSS-Cobalt coated blades are used for stainless and steel applications.

Inserts are easily reground to original accuracy.

High shear cutting action eliminates secondary burrs.

Used in manual and CNC applications with a 3-45mm countersink range.
