This lot of twelve CAT40 tool holders is a versatile, well-rounded set for outfitting the tool carousel of a vertical or horizontal machining center. The group includes small collet and drill holders for precise, close-tolerance hole work, extended bore holders for reaching into deeper features, and ER collet chucks for flexible gripping of round-shank cutters. 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 blend of small precision holders and extended-reach units suits detailed drilling and boring alongside everyday milling. Bought as a used set, this tooling keeps a machining center fully equipped and ready for work. MakeVarious ModelCAT40 Year2010 or older Product #16376 Price Please login to see price.
