## Description

Brand: GBJ Material: Steel Tungsten Carbide

Review: Running for about 3 hours total. No deeper than .020 a pass, 2200 rpm, 3ipm, coolant. Boom catastrophic failure. Sure its not expensive. Its a small diameter cutter. But failure that quickly on a 0.010 pass with mellow feed.. thats not ok. The grain of the metal in the cutter appears cast. Wouldnt buy again.
Review: Cuts mild steel like butter. I’m not sure about life span yet.
