- Drill bit tip delivers effective drilling / breaking longer. - Drill bit tip maintains its effective drilling / breaking edges longer. - 4 cutter tip enables a more circular hole to be drilled.
- The non-woven abrasive material is arranged in multiple (axial) disc layers. - Since the individual non-woven discs are not interconnected, the abrasive surface adapts easily to different workpiece contours, e.g. when working on profiles or pipes.
- Precision ground twist drill bit for rapid drilling, long life and excellent concentricity. - Manufactured from High Speed Steel to DIN338. - Ground from solid stock right hand cutting, type N flute, precision ground at 118° point angle.
