Value Collection 210-3804 Milling Machine Arbor Stub Style

Product Description

The VALUE COLLECTION 210-3804 is a stub-style milling machine arbor designed for use with horizontal milling machines and milling attachments. It features a straight shank configuration with a 3/4 inch shank diameter and a 5/8 inch arbor diameter, making it suitable for mounting milling cutters in precision machining setups. The overall length measures 4.281 inches (108.74 mm), and the shoulder-to-nut length is 1 inch (25.40 mm). At 0.7 pounds, this arbor is a compact, direct-mount toolholding component installed by machinists and toolroom technicians in production and maintenance environments.

This arbor is suited for horizontal milling operations where a stub-style, short-reach arbor is preferred to minimize deflection and maximize rigidity during cutter engagement. It is commonly used in toolroom setups, manual milling machines, and light to medium-duty production milling where straight-shank arbor compatibility is required. The 5/8 inch arbor diameter accommodates standard bore milling cutters designed for that size. Typical applications include face milling, slotting, and side milling operations across general metalworking environments.

Key Features

• Stub style arbor design minimizes overhang and reduces cutter deflection
• Straight shank with 3/4 inch diameter for direct-mount machine compatibility
• 5/8 inch arbor diameter fits standard bore milling cutters
• Shoulder-to-nut length of 1 inch provides consistent cutter seating
• Compact overall length of 4.281 inches suits tight-clearance milling setups
• Lightweight at 0.7 pounds for easy handling and tool change efficiency

Compatibility

Designed as a direct-mount toolholding arbor for horizontal milling machines accepting a straight shank with 3/4 inch shank diameter and 5/8 inch arbor diameter. Consult machine documentation to confirm spindle and collet compatibility before installation.

Installation Notes

Installation is performed by machinists or toolroom technicians. The machine spindle must be fully powered down and brought to a complete stop before mounting or removing any arbor. Verify that the machine spindle bore and drawbar thread are compatible with the straight shank before seating the arbor. Use appropriate cutter retention hardware and torque fasteners per machine manufacturer specifications to secure the milling cutter on the arbor.
