3M 7000045770 Roloc Shank 1/4 in 1-4-20 External

Product Description

The 3M 7000045770 is a Roloc shank designed to mount Roloc abrasive discs and accessories onto power tools equipped with a standard 1/4-inch keyed or collet chuck. The shank features a 1/4-20 external thread that accepts the Roloc twist-and-lock disc system, allowing for fast, tool-free disc changes during grinding, blending, or surface preparation work. At 0.029 pounds, it is a lightweight adapter used by metalworkers, fabricators, and finishing technicians in industrial and trade settings. This component is the interface between the rotary tool and the abrasive disc, and its correct installation directly affects disc retention and operator safety.

This shank is suited for use with die grinders and other rotary tools that accept a 1/4-inch shank. It is typically used in metal fabrication shops, automotive body work, HVAC ductwork prep, and general mechanical finishing applications where Roloc-style abrasive discs are the specified consumable. It is sold as an individual unit and is compatible with the full Roloc disc and accessory system.

Installation Notes

Installation is performed by metalworkers or finishing technicians using a standard collet wrench to secure the 1/4-inch shank in the tool chuck to the tool manufacturer specified torque.
