This lot of seven CAT50 tool holders is a compact, reliable set for outfitting the tool carousel of a large-frame vertical or horizontal machining center. The group includes big-bore holders for large-diameter tooling and shell mills, an extended-reach ER collet chuck for deep pockets and recessed features, and a threaded-nose holder for secure collet clamping. 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. The big-bore holders handle heavy mounted tooling while the extended ER chuck reaches into deep features. Bought as a used set, this tooling keeps a machining center fully equipped and ready for work. MakeVarious ModelCAT50 Year2010 or older Product #16373 Price Please login to see price.
