Value Collection SC08180242 Arbor Spacer Alloy Steel

Product Description

The VALUE COLLECTION SC08180242 is a hardened and ground alloy steel arbor spacer designed for use with milling machine arbors. With a 7/8 inch inner diameter, a 1-3/8 inch outer diameter, and a 3/8 inch thickness, this spacer provides precise, rigid positioning of cutting tools and arbor components. It is manufactured from alloy steel and hardened and ground to ensure dimensional accuracy and resistance to wear under repeated use. Machinists and toolroom professionals rely on spacers like this to maintain correct cutter spacing and axial positioning on horizontal and vertical milling setups.

This arbor spacer is suited for toolroom, production, and maintenance machining environments where consistent cutter placement is required. It fits standard milling machine arbors with a 7/8 inch bore. Typical applications include spacing end mills, side milling cutters, and other arbor-mounted tooling on knee mills and horizontal milling machines. The compact dimensions and hardened finish make it appropriate for both light-duty and moderate-production milling operations.

Key Features

• Hardened and ground alloy steel construction for dimensional accuracy and wear resistance
• 7/8 inch inner diameter sized for standard milling machine arbors
• 1-3/8 inch outer diameter provides adequate bearing surface for cutter positioning
• 3/8 inch thickness for precise axial spacing of arbor-mounted tooling
• Compact and lightweight at 0.09 pounds for easy handling during setup

Compatibility

Designed as an OEM-style replacement or supplemental spacer for milling machine arbors requiring a 7/8 inch bore and 1-3/8 inch outer diameter spacer.

Installation Notes

Installation is performed by machinists or toolroom technicians during arbor tool setup. Always power down and lock out the milling machine spindle before installing or removing arbor spacers. Ensure the arbor, spacer faces, and cutter bore are clean and free of chips or burrs before assembly. Do not exceed the machine spindle speed rating or the arbor load capacity when using arbor-mounted tooling assemblies.
