Diamond Tools for Concrete Floor Prep and Grinding

Chelsea Diamond Quick Change metal bond segments are among the best tools for floor grinding on the market. They come in several metal bonds designed specifically for the different types of concrete hardness:

Black: 1st cut,  25/30 grits, for concrete floor prep    

Red: 2nd cut, 40/50 grits, for removal scratch 

White: 3rd cut, 80/100 grits, for removal scratch 

Yellow: 4th cut, 120/140 grits, for the final step

The Quick Change metal bond tools are offered with one and two segments. Choosing between one or two segments allows the operator to control the speed and aggressiveness of the cut. Two segment shoes are designed for heavier machines and are not recommended for machines smaller than 25 inches. Single-segment tools are designed for lighter machines, or where aggressive stock removal is required. We recommend using single-segment shoes for the first step even with heavier machines for faster opening of the concrete.



Chelsea Diamond PCD shoes are available with the same Quick Change technology as the standard metal bond tools. They are designed for aggressive stock and coating removal. Our PCD shoes are available for right and left-hand rotation. Planetary machines WITH THE EXCEPTION require standard right-hand rotation tools.
