Value Collection SC08200073 Arbor Bushing 1 in Alloy Steel

Product Description

The VALUE COLLECTION SC08200073 is an alloy steel machine tool arbor bushing designed to reduce the bore of milling machine arbors to accept smaller-shanked tooling. With a 1-inch hole diameter, a 2-1/8-inch outside diameter, and a body length of 3-3/4 inches, this bushing provides a precise, stable interface between the arbor and cutting tool. A total indicated runout (TIR) of 0.0004 inches ensures tight concentricity, which is critical for maintaining cut quality and extending tool life in precision milling operations. Weighing 2.5 pounds, the alloy steel construction delivers the rigidity and wear resistance expected in production and toolroom environments. Licensed machinists and machine tool technicians are the primary installers.

This arbor bushing is suited for use with milling machine arbors in both production-floor and toolroom settings. Typical applications include horizontal milling setups where a standard arbor bore does not match the tooling shank diameter. The bushing adapts the arbor to accept the correct tool size without the need for a dedicated arbor, reducing tooling inventory costs and downtime during setup changes. It is appropriate for light to moderate material removal operations where concentricity and rigidity are priorities.

Key Features

• 1-inch hole diameter accommodates common milling tool shanks
• 2-1/8-inch outside diameter for fitment in standard milling machine arbors
• 3-3/4-inch body length provides extended support and stability
• 0.0004-inch TIR for high-concentricity tooling setups
• Alloy steel construction for rigidity and wear resistance in machining environments

Compatibility

Designed for use with milling machine arbors. Verify arbor bore and tooling shank dimensions before installation to confirm fitment.

Installation Notes

Installation is performed by machinists or machine tool technicians. Power down and lock out the milling machine before inserting or removing arbor bushings. Ensure the arbor, bushing bore, and tool shank are clean and free of burrs or debris before assembly to preserve the stated runout specification. Follow applicable shop safety standards and machine manufacturer guidelines during tooling changes.
