3M 7000121185 Spindle Extender Kit 5/8-11 Thread

Product Description

The 3M 7000121185 is a spindle extender kit designed to extend the reach of grinding and finishing equipment spindles for use with Scotch-Brite wheels. The kit features a 5/8-11 internal thread on one end and a 5/8-11 external thread on the other, allowing it to connect between a tool spindle and a wheel hub. Supplied as a single unit, it is well suited for shop maintenance environments, fabrication operations, and surface finishing applications where additional spindle length is needed to accommodate larger wheel setups.

This spindle extender kit is intended for use with Scotch-Brite wheels in 6-inch and 8-inch diameter sizes. It is commonly installed by maintenance technicians, fabricators, and surface finishing professionals working with bench-mounted or right-angle finishing tools that require extended spindle reach for proper wheel positioning and clearance.
