Always sharp drill bits

The DBS-22 Drill Bit Sharpening Attachment allows you to sharpen your drill bits from 3 mm (1/8") to 22 mm (7/8") in diameter with maximum precision and to give a four-facet point for best performance. The optimum tip and lip relief angle can be set for each drilling operation, taking into account the drill bit size and material. You can also sharpen broken bits back to the perfect shape.
