This lot of ten CAT40 tool holders is a flexible, collet-focused set for outfitting the tool carousel of a vertical or horizontal machining center, with one holder already fitted with a small shell mill ready to run. The TG and ER collet chucks accept a broad range of collet sizes, so a handful of holders grip many round-shank cutter, drill, and reamer diameters. CAT40 (also called CV40 or V-Flange 40) is the most widely used 40-taper standard on production VMCs from builders such as Haas, Mazak, Fanuc, and Doosan, prized for its balance of speed, rigidity, and fast tool changes. Buying a matched group of holders together saves the time of sourcing pieces one at a time and gets a spindle production-ready faster. Compared with lighter 30-taper tooling such as BT30, these CAT40 holders offer a larger gauge diameter and far greater rigidity, handling real roughing and interrupted cuts that a 30-taper spindle cannot. With both TG and ER collet systems in the lot, changeovers stay fast across a wide span of tool diameters. Bought as a used set, this tooling keeps a machining center fully equipped and ready for work. MakeVarious ModelCAT40 Year2010 or older Product #16378 Price Please login to see price.
