Choosing the Right Diamond Quality for Concrete Polishing  

If you want to give your concrete the best finish, use the right diamond polishing disc or pad. There are many different types out there, including different names, sources, and of course, prices. The options can actually be confusing, and what usually happens is people ultimately choose based on the price. This is sad because in a lot of cases, a cheap choice will only increase your long-term costs.

In any case, choosing the right disc begins with understanding your needs and plans. Will you use it for general polishing? For heavy stock removal? Are you aiming for a high gloss result? Size, thickness and the pattern on the cutting surface are the three most obvious considerations for choosing concrete polishing diamonds, but looking deeper, you need to assess the quality of the diamonds itself.

Although it's easy to look into the thickness, size and pattern of a diamond pad, it's almost impossible to check on the quality, grading and quantity of the diamonds that were used to make it. In the end, the diamonds will be doing the cutting, and they dictate how much the pad costs. More diamonds means a higher price, and higher quality diamonds means better grading,

If you look in the market, you will find diamond polishing pad from diamondtools.stonekor.com prices starting from $1 to $100, and they look nearly the same. What you won't see are the diamonds, and that's the reason you need a supplier you trust.

The priciest pads use highest quality industrial diamonds, with diamond concentration high and gradation narrow. Diamonds, like sand and gravel, are made in a whole range of sizes. Gradation refers to the difference in the sizes of the diamonds, so a narrow gradation means all the diamonds are of almost uniform in size. The disc's grit number more accurately describes diamond size gradation. Changes favor smaller diamonds which have no impact on the concrete's quality. Low grade diamonds are used to make cheap discs, which usually have way poorer gradation and general flaws. For more info about diamond tool, visit https://www.britannica.com/topic/diamond-gemstone.

Additionally, less diamonds may be used to make the pad. The gradation is usually wider, so for a 100 grit pad, you can expect a lot of diamonds that are smaller or coarser than the rest. The right STONEKOR Diamond Tooling leads to low quality polishing results and even more surface scratches, as well as slower cutting since there will be smaller diamonds in the disc.
