This lot of ten CAT40 tool holders is a versatile, reliable set for outfitting the tool carousel of a vertical or horizontal machining center. The group includes TG and ER collet chucks for flexible gripping of round-shank cutters across a wide diameter range, a boring bar holder already fitted with an insert tool for precise bore finishing, and threaded-nose holders for secure collet clamping. 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. The ready-to-run boring holder plus both TG and ER collet systems make this a well-rounded lot for milling and precise boring alike. Bought as a used set, this tooling keeps a machining center fully equipped and ready for work. MakeVarious ModelCAT40 Year2010 or older Product #16377 Price Please login to see price.
