This lot of nine CAT50 tool holders is a straightforward, reliable way to build out the tool carousel on a large-frame vertical or horizontal machining center. The set includes face mill holders for running shell and face mills, a collet chuck for precise gripping of round-shank cutters, and end mill holders for solid end mill retention. 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, the CAT50 holders in this lot deliver a larger gauge diameter and greater contact area at the spindle, which translates into more clamping force, better damping, and the rigidity needed for aggressive material removal on large parts. Where a CAT40 setup can chatter under heavy roughing loads, CAT50 tooling holds its cut, making it the better choice for shops running large molds, energy components, or heavy structural work. Bought as a used set, this tooling keeps a machining center fully equipped and ready for work. MakeVarious ModelCAT50 Year2010 or older Product #16278 Price Please login to see price.
