- The counterbore is used to enlarge a preformed hole when a flat bottom is required or to spot face when a machine finish is required
- The counterbore is an end cutting tool which may utilize a pilot to align the enlarged hole being machined with the preformed hole
- Tool geometry and carbide grade appropriate for material being machined
- Carbide tips brazed to tough hardened alloy steel body
- Precision ground cutting edges
- Steel cutting counterbores have secondary end relief on carbide for increased cutting edge strength
- The 3-flute counterbore tends to reduce chatter and improves finish
