Radiac 34078809 8"x 1/2"x 1-1/4" RA46-G800-VOS Ruby Surface Grinding Wheel

The RADIAC 34078809 is an 8-inch by 1/2-inch ruby surface grinding wheel engineered for precision shop work. Built with a RA46-G800-VOS specification, it provides machinists and fabricators with a tough abrasive wheel designed for dedicated surface grinding applications.

This wheel features a ruby color and utilizes a tough abrasive designed to deliver excellent form holding during operation. The specification includes an open and closed structure, with the -VOS suffix explicitly denoting an open structure build. This open construction allows the wheel to manage material removal while maintaining its structural profile.

In terms of limits, the wheel operates with a strict maximum speed rating of 3,600 RPM, meaning it cannot be used on higher-speed machinery. It also features a 1-1/4-inch arbor hole and a 1/2-inch thickness, requiring equipment that matches these exact physical dimensions. The product listing does not state specific metal compatibility or workpiece guidelines.

Verdict: The RADIAC RA46-G800-VOS is a dependable choice for operators needing a tough 8-inch ruby surface grinding wheel with excellent form holding. It is best suited for grinders that match its 1-1/4-inch arbor and operate within its 3,600 RPM limit.
