The new Rocky Mountain Twist Tri-Cam countersinks are designed with high-flow flutes for excellent material evacuations and finely tuned cutting edges for a smoother countersink finish. This results in a smooth, consistent finish for true fastener interface.

The countersinks are manufactured from fully hardened steel for optimal cutting edge and thread life and are available in both M2 high-speed tool steel and M42 cobalt. Precision CNC diamond machining insures exact specifications and consistency.

Features include non-marring self-guiding pilot, finely tuned cutting edges that deliver smoother countersink finish, and oversized cross-hole that allows easy countersink removal.
