Because CBN (cubic crystalline boron nitride) is a much harder abrasive than even silicium carbide or corundum, a better and sharper cutting edge is achieved - without burrs. And, with higher dimensional precision the countersinkers will last considerably longer while maintaining the precise tolerances. Because of the CBN deep-ground flutes the cutting edges are extremely sharp. Ideal for burr- and chatter-free deburring and countersinking. Applicable for steel, cast iron, non-ferrous and light metals.Best results at low cutting speeds.

The ideal tool for countersinking and deburring in the following sectors of industry: electrical, sanitary engineering, heating technics,mechanical engineering, switching systems,tubular steel construction, furniture and wood

working, automotive and aviation.

This tough tool is suitable for all standard industrial materials: non-ferrous metal, staiNless steel, thermoplastics and duroplastics as well as sheet metals.
