This lot of six BT40 tool holders is a ready-to-cut set for outfitting the tool carousel of a vertical or horizontal machining center. The group is loaded with productive tooling: an Erickson boring head for precise, adjustable bore finishing, indexable face and shell mills for high-metal-removal surfacing, and an insert drill for fast hole-making. BT40 (also called MAS-BT 40) is a widely used 40-taper standard on production machines from builders such as Mazak, Mori Seiki, Fanuc, and Doosan, prized for its balance of speed, rigidity, and fast tool changes. Buying a matched group of holders and cutters together saves the time of sourcing pieces one at a time and gets a spindle production-ready faster. Compared with lighter 30-taper tooling such as BT30, these BT40 holders offer a larger gauge diameter and far greater rigidity, handling the roughing and interrupted cuts that a 30-taper spindle cannot. With a name-brand Erickson boring head and indexable cutters already in the set, much of this lot can go straight to work on real parts. Bought as a used set, this tooling keeps a machining center fully equipped and ready for work. MakeVarious ModelBT40 Year2010 or older Product #16379 Price Please login to see price.
