Product Description

The 3M 7000120459 is a disc pad hub designed to mount abrasive face plates onto right angle grinders equipped with 5/8-11 external short shafts. The hub features a metal insert that threads onto shafts ranging from 0.375 inches to 0.5 inches in length, creating a secure connection between the grinder and the face plate. At 0.26 pounds, this lightweight hub adds minimal mass to the tool assembly. It is a single-piece accessory used by metalworkers, contractors, and maintenance technicians who rely on right angle grinders for grinding, blending, and surface preparation tasks.

This disc pad hub is suited for use with face plates ranging from 4.5 inches to 9 inches in diameter. It is intended for right angle grinder applications where the tool spindle uses a 5/8-11 external thread with a short shaft configuration. The hub is compatible with most standard face plates, making it a practical connecting component across a range of disc sizes commonly used in metal fabrication, construction, and industrial maintenance settings.
