"Rounds" holes edges offer an improvement over the chamfer:

3N1 SPOTTING DRILL
It won't break off in the work.

The new Severance 3N1 Countersink is a spotting drill and countersink that won't break off in the work like standard spotting drills. And for small holes in thin materials it can perform all three operations... spotting, drilling and countersinking.

Severance's Chatterless flute design also allows it to be used as an edge chamfering tool for linear or circular interpolated chamfering. You'll get an extremely smooth finish because it won't throw a burr down or up. Call your Severance Tool Distributor or Severance Tool for more information.
