Osborn 0007500800 Drive Arbor 1/4 in Wheel Brush

Product Description

The OSBORN 0007500800 is a drive arbor designed to mount small-diameter wheel brushes to rotary tools and die grinders. It converts a 1/4 inch arbor hole to a 1/4 inch shank, allowing standard wheel brushes to be chucked into tools with a 1/4 inch collet or chuck. The arbor does not include an attached spindle and is not a flow-through design. It is a compact, direct-drive adapter suited for deburring, surface prep, and finishing applications where small wheel brushes are the working tool. Installation and removal are straightforward for any metalworking or maintenance tech working with bench grinders, die grinders, or flexible-shaft machines.

This drive arbor is intended for use with small-diameter wheel brushes in light industrial, maintenance, and fabrication settings. Typical applications include weld cleanup, rust removal, edge deburring, and surface conditioning on metal workpieces. The 1/4 inch shank fits the collet size common to most die grinders and rotary tools used in HVAC, plumbing, and general metalworking trades. The 0.375 inch bolt hole diameter accommodates standard wheel brush mounting hardware.

Installation Notes

Installation is performed by threading or pressing the wheel brush onto the arbor and securing it per the brush manufacturer's hardware specifications, then inserting the 1/4 inch shank into the tool collet and tightening firmly. Always confirm the tool is unplugged or the air supply is disconnected before mounting or removing any abrasive accessory. Verify that the wheel brush speed rating meets or exceeds the tool's maximum RPM before operation. Follow applicable ANSI and OSHA abrasive wheel safety guidelines when mounting and running wheel brush assemblies.
