Dimar DIM-101RC4-12 Straight Bit With Center BB 6


This ultimate double flute template bit with a central ball bearing is recommended to get greater balance and when finer finish is a priority. This bit was designed for high production work with maximum chip clearance for faster feed rates. The ball bearing guide will ride along with the template, and the carbide teeth will cut into the material at the exact diameter of the bearing, hereby copying the design flush with the bearing’s diameter.
