💡 How do pro carpenters get accurate counterbore depths consistently?
Dialing in the feed pressure and tracking metal thickness pays off big. Here is the breakdown:
- M2 high speed steel retains geometry longer under heavy side loads
- Fluted pilot centers spin true to kill wobble before cutting initiates
- Adjustable nylon collars snap onto the shank collar for repeatable setbacks
Slow motor speeds reduce friction build up so the cutting surfaces stay cold
