Product Overview
Metric contour work at a slightly smaller scale, that's where the M142-040-BN-ALTiN fits in. This 4mm diameter 4-flute ball end mill carries a 2mm radius, sized for small 3D surfaces, pocket blending, and fine finishing in millimeter-based programming.
ALTiN coating helps this metric cutter handle heat and wear more confidently than an uncoated version would, especially on longer contour passes. With a 30° helix and single-end design, it's a practical option for mild steel, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites.
