Norton 66261080523 Flap Wheel Reducer Bushing

Product Description

The NORTON 66261080523 is a flap wheel reducer bushing designed to adapt a 1-inch center hole down to a 1/2-inch arbor. This hardware accessory allows flap wheels with a 1-inch bore to mount securely on grinders and bench tools fitted with a 1/2-inch spindle. It is a straightforward, single-piece adapter used by metalworkers, fabricators, and maintenance technicians who run abrasive flap wheels on various power tool platforms. The bushing eliminates the need to source a separate wheel with a different bore size, keeping tooling costs low and downtime short.

This reducer bushing is compatible with 4-inch to 6-inch diameter flap wheels that have a 1-inch center hole. It is suited for light fabrication shops, maintenance facilities, and industrial settings where multiple grinder spindle sizes are in use. Installers typically use it when mounting a flap wheel on an angle grinder, bench grinder, or arbor that has a 1/2-inch spindle but the wheel was sourced with a 1-inch bore.

Installation Notes

A qualified technician or experienced operator should install this bushing following the tool manufacturer's guidelines. Always power down and disconnect or de-energize the grinder or arbor before mounting or removing abrasive accessories. Confirm the bushing is seated flush and the wheel is secured with the correct flange and locking nut before resuming operation. Inspect the bushing and wheel for damage before each use.
