A concrete grinding wheel is an aspect of a grinding machine that fits within it for abrasive cutting operations. They are made from a coarse particle aggregate such as ceramic, silicon carbide or aluminum oxide. However, the hardest and most common aggregate for these tools is diamond since it is capable of sanding down floors of any hardness.

Types of concrete grinding wheel

Grinding cup wheel

A concrete grinding cup wheel is the most common tool for polishing concrete  and stone. Depending on the grit used, it can also take on jobs like removing adhesive from concrete surfaces.

Grinding dish wheel

Dish wheel looks similar to cup wheel, but they have a thinner surface edge. They also are more shallow. Because of this, they can fit into thinner areas and tight crevices that a cup wheel would not be able to squeeze into.

How are grinding wheel used?

Grinding wheels are inserted into the concrete grinder prior to use. Whether you're using a hand-held grinder or walk-behind grinder, you will need to install the wheel into the body of the machine. You then can turn it on and guide the machine over the surface that you're grinding down so that the abrasive particles level the surface out and eliminate blemishes. The end result is a smooth concrete surface that has none of the naturally sharp or grainy parts that occur after it has dried.

Diamond tools are by far the best abrasive tools for concrete grinders. They're able to grind down any material no matter how hard it is so you don't need to worry about it breaking halfway through a contracting job. However, there are a few factors that you need to consider.

The first is the size of the grinding wheel you need. You must select the grinding wheel that fits seamlessly within the machine that you plan to use. Make sure to measure the diameter of your machine appropriately and select  the grinding wheel with the necessary size.

You also must consider whether you want a single or double row diamond grinding wheel. Double row grinding wheel will perform twice as intensely and will therefore smooth uneven surfaces down perfectly. However, they're more expensive.
