This lot of ten CAT50 tool holders is a rigid, milling-focused set for outfitting the tool carousel of a large-frame vertical or horizontal machining center. The group includes end mill holders for solid end mill retention, a stub milling arbor for short, rigid mounting of shell mills close to the spindle, and a big-bore holder for large-diameter tooling. 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 stub milling arbor in particular keeps cutters close to the spindle for maximum rigidity on demanding passes. Bought as a used set, this tooling keeps a machining center fully equipped and ready for work. MakeVarious ModelCAT50 Year2010 or older Product #16371 Price Please login to see price.
