This is a new Sandvik Coromant CoroDrill 860 solid carbide twist drill, part number 860.1-0635-032A1-MM 2214, with a 0.25 in (6.35 mm) cutting diameter and a 1.291 in (32.8 mm) cutting length (LU). The grade designation CZCms Ø8 indicates this is a PVD-coated micro-grain carbide substrate — the distinctive copper/bronze coloration visible on the flutes is consistent with Sandvik's proprietary Zertivo (CZ) PVD coating, engineered for extended tool life in steel and stainless steel applications. The 860.1 series features a straight shank with a nominally larger shank diameter than the cutting diameter, a 140° point angle, and parabolic flute geometry optimized for chip evacuation in through-hole drilling operations on CNC machining centers. The drill is compatible with standard hydraulic, shrink-fit, and precision collet chucks accepting a 3/8 in or 10 mm straight shank; verify shank diameter against the 860.1-0635-032A1-MM series published dimensions before toolholder selection.
