The Right Diamond Tools for Job
Mar 05 , 2021


Understanding how diamond tools work is necessary for anyone who wants to be successful in this industry. Diamonds are not all the same. The two terms most often used when speaking of diamond tools are diamond grit and bond. Most diamond tools are made of synthetic diamond powder, measured in microns and called grit, and a bonding material, usually metal or resin, or a combination of bonding materials (hybrid tools). They are bonded together through injection molding, hot and cold pressing, electroplating, and vacuum brazing.


The two most common problems that you can run into are:

1. The tools cut aggressively but their life is too short (premature wear). This usually happens when using soft bond on soft / abrasive floors;

2. The tools don't cut well and just slide on the floor surface. This happens when using hard bond tools on hard concrete. Often, adding water helps avoid glazing as well as removing weights, and slowing down a bit. However, sometimes you should just switch to a softer bond.


It is best to test the concrete hardness first, and make sure you are using the correct bond tools. Each grit is designed to refine the scratch pattern, and the rule of thumb is each consecutive grit is to be approximately doubled in size, so it can remove the scratches of the previous step. For example, if you start with 30 grit, the next grit is 50 or 70, then 100 or 120, 200 or 220, 400, 800, etc. Following proper grit sequence is a fundamental principle in concrete processing. Skipping a grit step will encounter some serious scratched floor challenges.
