This lot of nine BT50 tool holders is a well-rounded, reliable set for outfitting the tool carousel of a large-frame machining center. The group covers a broad span of work: collet chucks for precise gripping of round-shank cutters, an end mill holder for solid end mill retention, a big-bore holder for large-diameter tools and shell mills, a drill chuck for quick drilling, and a threaded-nose holder for secure collet clamping. BT50 is the heavy-duty 50-taper standard common on high-torque machining centers from builders such as Mazak, Mori Seiki, Okuma, and Doosan, and it is valued for its rigidity in roughing and heavy cutting. Compared with lighter BT40 tooling, these BT50 holders offer a larger gauge diameter and greater spindle contact, delivering more clamping force, better damping, and the rigidity needed for aggressive material removal on large parts. Assembling this range of holder types one at a time would take time and leave gaps; here a single lot covers milling, drilling, boring, and collet work in one buy. Bought as a used set, this tooling keeps a machining center fully equipped and ready for work. MakeVarious ModelBT50 Year2010 or older Product #16280 Price Please login to see price.
