Product Overview
Metric contour work needs its own dedicated cutter, and the M142-080-BN-ALTiN fills that role at 8mm diameter. This 4-flute ball end mill is built for profile and contour milling in millimeter-based programming, with a 4mm radius sized for real 3D surface work rather than just fine detail.
ALTiN coating helps this metric cutter handle heat and wear better than an uncoated equivalent, which matters on longer contour passes where the tool stays engaged for extended periods. With a 30° helix and single-end design, it performs reliably across mild steel, stainless, cast iron, titanium, non-ferrous metals, plastics, and composites.
