3M 7000120536 Flange Adapter 5/8 Inch Shaft Flap Wheels

Product Description

The 3M 7000120536 is a stamped and formed sheet metal flange adapter designed to reduce a 1-inch internal diameter core, flange, or wheel bore to fit shafts smaller than 1 inch in diameter. It allows 5 through 8 inch diameter flap wheels to be mounted on smaller spindles without requiring a different wheel or arbor. This adapter is a practical hardware solution for grinding and finishing operations where the drive shaft diameter does not match the wheel bore. Maintenance technicians and fabrication professionals commonly use this type of reducer to extend the utility of existing abrasive wheel inventory.

This adapter is suited for use in both shop and field settings where flap wheels are used on angle grinders, bench grinders, or similar rotary tools. It is intended for 5 through 8 inch diameter flap wheels and accommodates a 5/8 inch shaft. The stamped sheet metal construction keeps the component lightweight while providing consistent fitment during wheel changes. It is sold as a kit with a minimum order quantity of one.
