3M 7010362498 Wheel Adapter Kit 1/2-20 External

Product Description

The 3M 7010362498 is a wheel adapter kit designed to mount abrasive and surface conditioning wheels onto bench grinders and portable grinding equipment using a 1/2-20 external thread spindle configuration. The kit provides the hardware needed to fit wheels with arbor hole sizes of 1/2 inch, 5/8 inch, or 1 inch, making it a versatile solution for shops running multiple wheel sizes on a single machine. It is installed by grinding equipment operators, maintenance technicians, and metalworking professionals who need reliable wheel mounting without sourcing individual components separately.

This kit is intended for use with 3M Rubber Slotted Expander wheels as well as coated abrasive and surface conditioning wheels. It is suited for bench grinder and pedestal grinder setups in industrial, fabrication, and maintenance environments.
