Frequently Asked Questions
What is the difference between the RBG 934 and the RBG 712?

The RBG 934 runs a 3/4 HP continuous duty motor and a larger 9-inch disc compared to the RBG 712's 1/2 HP motor and 7-inch disc. That means faster grinding, less heat buildup, and higher daily throughput for large commercial operations.
