### ⭐⭐⭐⭐⭐ Tough to beat for the price.
*by D***D on January 3, 2026*

A great single flute cutter for the money. I'm using it lightly for now, 1" DOC, .005 per flute at 7k RPM around a the outside of a 2-1/4" piece of round stock. Does a nice job and the final cut yields a diameter that matches G-code program with in a couple tenths. Will buy again!
