Value Collection 219-9560 Milling Machine Arbor 2in

Product Description

The VALUE COLLECTION 219-9560 is a Style B milling machine arbor with an NMTB50 taper shank, designed for use in horizontal milling operations where a large-diameter arbor is required. The arbor measures 2 inches in diameter and 31.75 inches in overall length, providing substantial reach for multi-cutter setups. With a shank diameter of 2.75 inches and a drawbar thread size of 1-8, it mounts securely in compatible milling machine spindles. This arbor is installed by machinists and toolroom professionals working with knee mills, horizontal mills, and similar equipment requiring NMTB50 tooling.

This arbor is suited for horizontal milling applications in job shops, toolrooms, and production environments where shell mills, side milling cutters, or straddle milling setups are run. The 24-inch shoulder-to-nut length provides ample working area along the arbor shank for gang milling configurations. The kit includes two running bushings and an arbor spacer, supporting straightforward setup on machines equipped with NMTB50 spindle interfaces.
