The GH-K has three exchangeable countersink blades which are precision ground as a match set to achieve unmatched countersink finishes. The tool feeds the coolant through an inner supply duct directly to the blade. GH-K is unique because of its large countersinking range from diam. Ø 3 to diam. Ø 25 or from diam. Ø 4 to diam. Ø 45 mm.

• High-performance countersink tool with three blades for chatter-free countersinking and circular cutting. 
• Wide countersink range from diam. 4 mm to diam. 45 mm with one single tool. 
• Exchangeable blades that can be re-sharpened, made of carbide or HSS and provided with a coating. 
• Tool body of rugged and high-precision design with through the tool coolant. 
• Tools available for 60° and 90° countersinks.

The three tip sits inside the tool body and the three carbide blades are manufactured to very tight tolerances. This enables optimal high-speed chatter-free production of countersinks on bores and chamfers of work piece edges.
