Rested tooth Corner Radius grind Variable pitch 4 flute carbide

Here a tool rest is used to govern  the corner location for grinding the corner
This is used because the flutes are unevenly spaced to quiet the tool down during the machining process
The indexing collar on the back of the tool spindle is used for non-variable or symmetrically located flutes

Production  Corner Radius Grinding  on multiple tools  goes very fast
Just be careful to slowly dry run the swing before turning on the machine

  Easy and Fast
