Product Description

The OSBORN 0007500000 is a wheel mandrel designed to mount abrasive or finishing wheels for use with rotary tools and die grinders. It features a 0.25 inch shank diameter, making it compatible with standard quarter-inch collets and chucks commonly found in pneumatic and electric rotary tools. This type of mandrel serves as the interface between the tool and the mounted wheel, transmitting rotational force to the abrasive accessory. It is used by machinists, fabricators, HVAC technicians, plumbers, and electricians for deburring, grinding, and surface preparation tasks in both shop and field settings.

Typical uses include deburring pipe ends, cleaning weld joints, removing corrosion from fittings, and general surface prep work. The 0.25 inch shank fits the most common collet size on die grinders, making this mandrel a practical shop consumable for tradespeople working with metal components.
