Grind the bit so that it has a 2-facet grind (the primary facet). No secondary facet is needed, and would probably weaken the bit's insert. The Tormek DBS-22 Drill Bit Sharpening Attachment can be used to sharpen this drill. |
Probably best to stay with the drill bit's geometry as supplied by the manufacturer.
