Value Collection 210-3806 Milling Machine Arbor Stub Style

Product Description

The VALUE COLLECTION 210-3806 is a stub-style milling machine arbor designed for use with horizontal milling machines and arbor-mounted cutters. It features a straight shank measuring 3/4 inches in diameter and an arbor diameter of 7/8 inches, providing a secure, concentric mount for shell mills, side milling cutters, and slitting saws. With an overall length of 4.406 inches (111.92 mm), this compact stub arbor keeps the cutter close to the spindle, reducing deflection and improving rigidity during cutting operations. Weighing 1.18 pounds, it is suited for production and maintenance machining environments where precision and stability are required.

This arbor is used in machine shops and manufacturing facilities running horizontal knee mills or arbor-type milling machines. It is appropriate for both light production work and toolroom applications where a stub-length arbor is preferred over a long-form arbor to maximize cutter stability. The shoulder-to-nut length of 1 inch allows for standard cutter spacing and spacer arrangement along the arbor body. Licensed machinists and tool-and-die professionals are the typical end users of this component.

Compatibility

Designed as an OEM-style replacement or direct-fit arbor for horizontal milling machines accepting a straight shank with a 3/4-inch shank diameter and a 7/8-inch arbor bore.

Installation Notes

Installation is performed by qualified machinists or tool-and-die professionals. Power down and lock out the milling machine spindle before mounting or removing the arbor. Ensure the spindle bore, collet, or adapter is clean and free of chips or debris before seating the straight shank. Verify cutter bore diameter matches the 7/8-inch arbor diameter before assembly, and confirm all spacers and the arbor nut are properly torqued per the machine manufacturer's specifications.
