Osborn 0007539600 Wire Wheel Adapter 1-1/4 to 5/8 Inch

Product Description

The OSBORN 0007539600 is a metal wire wheel adapter designed to reduce a 1-1/4-inch arbor hole down to a 5/8-inch mounting arbor. It allows wire wheels and wire cup brushes with a 1-1/4-inch center bore to mount onto grinders, bench grinders, or angle grinders equipped with a 5/8-inch spindle. The adapter is machined from metal for durability under the rotational loads typical of wire wheel applications. Tradespeople and maintenance professionals use this type of adapter when the wheel bore does not match the tool spindle, eliminating the need to source a separate wheel sized to the tool.

This adapter suits bench grinder and angle grinder setups where a 1-1/4-inch bore wire wheel must be fitted to a 5/8-inch arbor spindle. Typical applications include weld prep, rust and scale removal, surface cleaning, and deburring in fabrication shops, mechanical service bays, and general maintenance environments. It is a straightforward mechanical adapter with no electrical or fluid system involvement, suited for any trade or shop context requiring wire wheel use.

Key Features

• Reduces 1-1/4-inch arbor hole to 5/8-inch spindle for broad grinder compatibility
• Metal construction handles rotational stress and vibration of wire wheel operation
• Compact form factor adds minimal length between wheel and spindle
• Straightforward installation requiring no special tooling beyond standard arbor hardware

Compatibility

Designed for use with wire wheels and wire cup brushes that have a 1-1/4-inch center bore, adapting them to grinders with a 5/8-inch arbor spindle.

Installation Notes

Installation should be performed by a qualified technician or experienced shop professional. Always power down and fully unplug or de-energize the grinder before mounting or removing any wheel or adapter. Follow the grinder manufacturer's torque and flange requirements for wheel retention hardware. Inspect the adapter and wheel for cracks or damage before each use, and ensure the assembled wheel does not exceed the maximum RPM rating of either the tool or the wheel.
