Value Collection 210-3800 Milling Machine Arbor Stub Style

Product Description

The VALUE COLLECTION 210-3800 is a stub-style milling machine arbor designed for use with horizontal milling machines in machine shop and metalworking environments. The arbor features a straight shank configuration and measures 0.5 inches in both arbor diameter and shank diameter. Overall length is 4.031 inches (approximately 102.4 mm), with a shoulder-to-nut length of 1.0 inch. This compact stub design provides rigid support for milling cutters in applications where minimizing overhang is a priority. Installation is typically handled by machinists and toolroom technicians in industrial production and maintenance settings.

This arbor is suited for light-to-medium milling operations on horizontal milling machines where a straight-shank stub arbor is specified. The 0.5-inch arbor diameter accommodates standard milling cutters bored to that size. The stub style keeps the cutter close to the spindle nose, reducing deflection and improving cut stability. Typical use cases include keyway cutting, slotting, and face milling in job shop and production environments.

Key Features

• Straight shank configuration for straightforward spindle mounting
• 0.5-inch arbor diameter and 0.5-inch shank diameter for matched fitment
• Overall length of 4.031 inches suits compact horizontal milling setups
• Shoulder-to-nut length of 1.0 inch provides defined cutter seating
• Sold individually (package quantity of 1)

Compatibility

Designed as a replacement or supplemental stub-style arbor for horizontal milling machines that accept a straight-shank arbor with a 0.5-inch shank diameter. Confirm spindle bore and arbor retention method before installation.

Installation Notes

Installation and removal of milling arbors should be performed by qualified machinists with the milling machine powered down and locked out per OSHA lockout/tagout procedures. Ensure the spindle bore and arbor shank are clean and free of burrs before seating the arbor. Do not use excessive force to seat or remove the arbor, as damage to the shank or spindle taper can result. Verify cutter bore matches the 0.5-inch arbor diameter and that all arbor hardware is properly torqued before beginning a cut.
