Norton 66261080524 Flap Wheel Reducer Bushing 1 to 5/8 Inch

Product Description

The NORTON 66261080524 is a flap wheel reducer bushing designed to adapt a 1 inch center hole to a 5/8 inch arbor, allowing standard bench grinders and angle grinders with a 5/8 inch spindle to accept flap wheels bored to 1 inch. This type of bushing is a straightforward hardware solution for shops and tradespeople who stock flap wheels in a single bore size and need to run them on multiple tool platforms. At 0.5 pounds, the part is compact and easy to stock as a consumable alongside abrasive supplies. Installation requires no special tooling beyond standard arbor wrenches.

This reducer bushing is rated for use with 4 inch to 6 inch diameter flap wheels bored to 1 inch. It suits metalworking, fabrication, and finishing applications where flap wheels are used on grinders or arbor-driven setups with a 5/8 inch spindle. Typical users include metal fabricators, welders, and maintenance technicians who require a reliable bore adapter to mount abrasive flap wheels without sourcing specialty-bored product.

Always power down and disconnect or de-energize the grinder before mounting or removing any abrasive accessory. Verify that the flap wheel bore seats fully and evenly on the bushing before tightening the arbor nut. Follow the grinder manufacturer's torque and guard requirements as well as applicable ANSI B7 abrasive safety standards.
