Diamond tooling is the set of abrasive pads, segments, and discs attached to floor grinders and polishers. Industrial diamonds are bonded into metal or resin and cut into the concrete surface. Tooling comes in grits from coarse to very fine. Working through the grits in order is what refines concrete from rough to glossy.
What Diamond Tooling Means for Your Floor
Think of diamond tooling as the sandpaper for concrete. Concrete is too hard for regular abrasives, so the cutting bits are diamond grains held in place by a bonding material. As the bond wears, it exposes fresh diamonds, so the tool keeps cutting.
There are two main families. Metal-bond diamonds do the coarse grinding, and resin-bond diamonds do the finer polishing that builds the shine. The grit number on each tool tells you how coarse or fine it is.
You won’t pick tooling yourself. It matters because it drives the job. Each extra step through finer tooling takes more time, and a higher shine needs more of those steps. That’s part of why a glossier floor usually costs more.
Diamond Tooling FAQ
What is a diamond tool?
It’s a cutting or grinding tool with industrial diamond grains bonded onto its working surface. On concrete floors, that means the pads and segments under a floor grinder. Diamonds are used because they’re hard enough to cut concrete and stone.
Why does diamond tooling come in different grits?
Each grit leaves a scratch pattern, and the next finer grit removes the scratches from the step before. Going through the grits in order takes a floor from rough to smooth to shiny. It’s like sanding wood with coarse paper first, then finer and finer sheets.
