Review on FomaSP MGMN300 M Grooving Carbide Inserts by Athenasby Whitney

Revainrating 5 out of 5

Work awesome for 17-4

I have an Accu-Size economical MGEHR cutting tool. I wasn't particularly impressed at first, but decided to give these inserts a try. In South Bend 9, easily cut a 1.5" piece of 17-4.

Pros
  • Long life, competitive price, high economy, improved working range, high temperature resistance, suitable for lightly interrupted cuts.
Cons
  • Long delivery time
