The first step in creating a tool bit is to grind the front relief For most work a relief angle of 10° works well While you are grinding the front relief you are also creating the front cutting edge angle Make this angle about 10° also so that the corner formed by the front cutting edge and the side cutting edge is less than 90°
Step 3 Grinding Bit Shaft Once holes have been created place metal grinding or cutting discs on the power drill and use it at medium speed to slowly grind down the shaft of remaining drill bits until they are no longer attached to metal shavings left behind cuttings disc
