3M 7000046162 Spindle Extender Adapter Radial Bristle Brush

Product Description

The 3M 7000046162 is a spindle extender adapter designed to increase the effective utilization width when using the standard 1 inch Scotch-Brite 8 inch Radial Bristle Brush. By spacing the brush further out along the spindle, the adapter allows technicians and tradespeople to reach work areas that would otherwise be inaccessible with a flush-mounted brush setup. The adapter measures 2 inches in length with a 0.5 inch shaft diameter and a 1 inch mounting dimension. Lightweight at 0.03 pounds, it is a simple add-on component that extends tool functionality without requiring additional equipment.

This spindle extender adapter is suited for use with surface preparation and finishing applications where Scotch-Brite Radial Bristle Brushes are used on a rotary tool or bench grinder. Typical applications include deburring, blending, and light surface conditioning on metal components in maintenance, fabrication, and general trade shop environments. The adapter is sold individually and is intended for professional use wherever consistent brush positioning and extended spindle reach are required.
