Cross hole countersink, 90°.Design: With cylindrical shank. With evenly running special relief grinding in the cone coat. The good blade geometry results in a light, spiral cut. The chips are pushed up in the shank direction by the inclined hole and cannot damage the countersink. This makes the countersink round and protects the machine spindle.Application: Suitable for light and chatter-free hole deburring and countersinking. Particularly suitable for long chipping materials. Sharpening is possible by simply resharpening using an abrasive pencil on the blade front. Spiral fluted with fixed pilot.
