The Stone Grind - 30" Cordless machine. Would you spend your days tied to a leash? Why let cords tie you down? Go Cordless!

The Stone Grind is the workhorse of the grinding fleet. 1000 lbs of machine grinding 12 Diamonds into the concrete is forceful to say the least.

The Stone Grind has a Robin/Subaru 653 cc propane engine, two vacuum ports and three 13” counter rotating heads for a total grinding width of 30”. Because each head contains 4 diamonds, the operator can walk faster and get better results. The Stone Grind increases production by 40% when compared with electric machines having a similar head pressure and horse power. Standard practice has been to complete a polishing job at 3000 grit. Contractors using the Stone Grind stop polishing at 800 grit and get the same outstanding results.
