Superabrasive has been manufacturing diamond tools since 1987 and offers diamond tools for concrete, natural stone, terrazzo, overlays,and other floor applications, including:

Superabrasive is the only company in the industry to manufacture both its own complete line of machines AND diamond tools. Superabrasive's diamonds for concrete (often called Lavina diamonds) are especially designed for use with Lavina machines but also have a proven record of excellent performance with other grinders and polishing machines on the market. Superabrasive's most popular tooling brands include the QuickChange tooling system (metals and pcd), NATO® resin discs, Calibra® ceramic discs, V-HARR® premium polishing pads, and ShinePro® pads for floor maintenance. As a manufacturer, we have a complete control over every stage of the production process of our diamond tools, from the diamond powder sifting and sorting to the end product, and we offer one of the best values on the market.

How diamond tools work

Understanding how diamond tools work is a must to any contractor who wants to be successful in this industry. As a diamond tools manufacturer with over 25 years of experience, we know how many variables are in the manufacturing process, and they all impact the performance of each tool. It is easy to copy the shape and design of a tool, but almost impossible to replicate the exact bond matrix and formula. Here are some basics about diamond abrasives that would give you a sense of why diamonds are not all the same, and how this affects your productivity and your bottom line. The two terms most often used are 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. They are bonded together through injection molding, hot and cold pressing, electroplating, and vacuum brazing.

Each grit is designed to refine the scratch pattern, and the rule of thumb is each consecutive grit 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 put you up against some serious scratched floor challenges. The grit steps are usually divided in 3 stages - grinding, honing and polishing.

Grinding

Grinding includes the steps from the lowest starting grit (it depends on the floor and application and could be as low as 6 grit but typically 30 or 50 grit) up to 120 grit. The tools used here are usually metal-bond tools, brazed tools for lippage removal and floor leveling, or pcd tools for coating and glue removal. There are many shapes and designs on the market – round button segments, rectangular segments, single, double or multiple, plugs, etc, etc. but what is more important, especially in the initial cutting steps, is the bond or hardness of the tools. Many contractors have trouble understanding how bonds work relative to different kinds of concrete. Depending on the bonding material, abrasives have different hardness which determines how diamonds are exposed. Hard concrete requires a softer bond to prevent glazing and to allow new diamonds to get easily exposed for maximum cutting. Soft concrete requires a harder bond, so it can last longer (soft bond will cut but it will wear out too fast on soft concrete).

Honing & Polishing

Honing includes the steps between 100 to 400 grit, the tools used in this stage are usually hybrids and/or resins. The hybrids, made of a combination of bonding materials – metals, resins, or ceramics (such as Superabrasive’s Calibra discs or HD discs), are especially useful for removing scratches left by the metal bond tools. Polishing is from 800 grit up to 3500 grit. The most popular choice for concrete polishing are resin pads/pucks, which are made of poly-phenolic and ester-phenolic. Another good solution are pads that use felt and drops of resin, such as Superabrasive’s V-HARR premium polishing pads, offered all the way up to 8500/Buff grit for maximum floor shine. Another thing to consider when choosing tools is that there are bonds / tools designed for wet use only, dry use only or wet/dry use. Improper use can cause problems like glazing, sticky residue on the floor, and so on.

Following all the grits may seem like a lot of steps, but well-trained contractors know that this is crucial for proper floor refinement and achieving a good wear-resistant floor finish. It is tempting to buy the cheapest diamonds but concrete grinding and polishing is a very labor-intensive business and lost productivity and time spent redoing a floor is much more costly.The point made is that not all diamond tools are created equal, and diamond tools should be always chosen relative to a specific project. Knowing what kind of concrete you are dealing with is important for finding the right combination of bonds and grits which will increase your productivity and ROI, and produce the best floor finish.
