The arbor measures 1.25 inches in diameter and 18.93 inches in overall length, providing substantial reach for gang milling setups or multi-cutter arrangements. The taper shank seats into NMTB40 spindle receivers, and the 5\/8-11 drawbar thread locks the arbor firmly during cutting. An arbor spacer is included. This component is installed by machining technicians and tool room operators working with manual or CNC knee mills and vertical machining centers equipped with NMTB40 spindle tapers.\u003c\/p\u003e\u003cp\u003eThis arbor is suited for production shops, tool rooms, and maintenance machining environments where repeatable, rigid cutter mounting is required. The Style A configuration features a straight cylindrical body with a shoulder and nut arrangement, with a shoulder-to-nut length of 12 inches. This length accommodates multiple spacers and cutters along the arbor body, making it appropriate for straddle milling and similar multi-pass operations on ferrous and non-ferrous workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNMTB40 taper shank for direct spindle mounting in compatible machines\u003c\/li\u003e\n\u003cli\u003e1.25-inch arbor diameter with 18.93-inch overall length for extended cutter reach\u003c\/li\u003e\n\u003cli\u003e12-inch shoulder-to-nut length accommodates multiple cutters and spacers\u003c\/li\u003e\n\u003cli\u003e5\/8-11 drawbar thread for positive spindle retention during milling\u003c\/li\u003e\n\u003cli\u003eStyle A design with included arbor spacer for setup flexibility\u003c\/li\u003e\n\u003cli\u003eWeighs 13 pounds for stable, low-vibration cutter support\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with milling machines equipped with NMTB40 taper spindles and a 5\/8-11 drawbar thread.
