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, with two end mill holders already fitted with cutters ready to run. The group also includes ER and TG collet chucks for flexible gripping of round-shank cutters across a wide diameter range and an extended arbor for reaching recessed surfaces. 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 two ready-to-cut end mill holders and both ER and TG collet systems, much of this lot can go to work immediately across a broad diameter range. Bought as a used set, this tooling keeps a machining center fully equipped and ready for work. MakeVarious ModelCAT40 Year2010 or older Product #16375 Price Please login to see price.
