This lot of ten CAT50 tool holders is a versatile, reliable set for outfitting the tool carousel of a large-frame vertical or horizontal machining center. The group includes extended-reach ER collet chucks for deep pockets and recessed features, large collet chucks for gripping big round-shank cutters, and a face mill arbor for running shell and face mills. CAT50 (also called CV50 or V-Flange 50) is the heavy-duty 50-taper standard used on high-torque machining centers from builders such as Haas, Mazak, Okuma, and Mori Seiki, and it is valued for its rigidity in roughing and heavy cutting. 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 40-taper tooling such as CAT40, these CAT50 holders deliver a larger gauge diameter and greater spindle contact, translating into more clamping force, better damping, and the rigidity needed for aggressive material removal on large parts. Between extended and large-capacity collet holders plus a face mill arbor, this lot spans deep-reach work, big-diameter gripping, and heavy facing. Bought as a used set, this tooling keeps a machining center fully equipped and ready for work. MakeVarious ModelCAT50 Year2010 or older Product #16370 Price Please login to see price.
