Product Overview
Hardened steels chew up cheap tooling fast — same with stainless, titanium, Inconel, Hastelloy. That's the whole reason the MX743-2500.015 exists. It's a 1/4" 4-flute solid carbide corner radius end mill, part of CGS Tool's VMAX MX743 Series, built for exactly this kind of unforgiving material.
What actually does the work is the variable helix paired with variable pitch. Instead of even spacing, the flutes are staggered, which breaks up the harmonics that cause chatter — so the cut stays smoother and material comes off more efficiently even under real load. Heat and wear get handled by the nACRo coating, which holds up through long, demanding CNC runs without breaking down early. The radius is small, just .015", but it's there for a reason: enough reinforcement at the edge to add real durability, without dulling down the sharp profile the job needs.
