3M 7000046130 Bristle Disc Mandrel 3/32 Inch Shank

Product Description

The 3M 7000046130 is a mandrel designed to hold small radial bristle discs in rotary tools, die grinders, and drill chucks used in surface preparation and finishing work. The mandrel features a 3/32 inch shank that fits standard drill or collet chucks, and accepts bristle discs up to 1 inch in diameter with a 1/16 inch center hole. It provides a secure mechanical connection between the rotary tool and the abrasive disc, keeping the disc centered and stable during operation. Typical users include metalworkers, maintenance technicians, and trade professionals performing weld cleanup, deburring, and surface conditioning tasks.

This mandrel is intended for use with small radial bristle discs 1 inch in diameter or smaller. It is suited for tight-clearance applications where a compact abrasive setup is required, such as tube interiors, weld joints, and confined surface areas. The 3/32 inch shank makes it compatible with a wide range of standard collet chucks and drill-style rotary tools commonly found in fabrication, HVAC, and mechanical service environments.
