Sandvik R216.33-10040-AC22U H10F 10mm 3FL Carbide Ball Nose End Mill

The Sandvik Coromant R216.33-10040-AC22U H10F is a new solid carbide 3-flute ball nose end mill from the CoroMill Plura series, made in Germany, designed for semi-finishing and finishing operations in a wide range of materials. Decoding the MPN: R216.33 = CoroMill Plura ball nose series; 10 = 10 mm cutting diameter; 040 = 40 mm overall length (confirmed by label: 10×10×22×72 mm — 10 mm cutting dia., 10 mm shank dia., 22 mm cutting length, 72 mm overall length); AC22U = 3-flute geometry with unequal helix for vibration damping; H10F = submicron-grain carbide grade with SIRON-A (AlTiN-based) black PVD coating optimized for hardened steels and heat-resistant superalloys up to ~65 HRC. The tool features a cylindrical shank and a full ball-nose profile suitable for 3D contouring, ramping, and copy milling on machining centers using ER, Weldon, or shrink-fit holders sized for 10 mm shank. The black PVD coating visible in the photos and the H10F grade designation confirm suitability for hard-material machining where thermal and abrasion resistance are critical.
