This lot of ten CAT50 tool holders is a rigid, milling-focused set of face and shell mill arbors, including quality SEM and Valenite units and one extended arbor for reaching recessed surfaces. These arbors mount large-diameter face and shell mills for high-metal-removal surfacing on a large-frame vertical or horizontal machining center. 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 arbors 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 arbors deliver a larger gauge diameter and greater spindle contact, translating into more clamping force, better damping, and the rigidity needed for aggressive face milling on large parts. The named SEM and Valenite arbors are proven, name-brand units, and the extended arbor adds reach for stepped or recessed faces. Bought as a used set, this tooling keeps a machining center fully equipped and ready for work. MakeVarious ModelCAT50 Year2010 or older Product #16369 Price Please login to see price.
