Malish Diamabrush concrete polishing tool
Diamabrush 400 Grit Polymer Polishing Tool



The 400 grit Polymer Tool is the 4th step in the Diamabrush concrete polishing process.

Typical blade life of the 400 grit Polymer Tool averages 100,000 sq. ft. or more. Always use the polymer tools with water. Using the polymer tools dry will quickly destroy the blades. These tools also must be conditioned by soaking in water for 72 hours before use. This conditioning will prevent the blades from being brittle and reduce the chance of breakage. All polymer blade tools are available in 12"-20" sizes. All grits of polymer blades are multi-directional and can be operated clockwise or counter-clockwise.

The Diamabrush system by Malish is an extremely affordable and effective way to prepare, profile or polish concrete floors. These tools are easy to use, require no special training and fit most all standard floor machines available at most rental stores.

To ensure the tool you order is a perfect fit for your specific machine and set-up, we custom build each tool per order. This allows us to ship most Diamabrush orders NEXT DAY, and of course shipping is always free to all 48 Continental United States!

Selecting The Right Tool


When ordering your new Polymer Polishing Tools you will need to know several things about the machine you will be using the tools on.


1. What is the make and model number of the machine the tools will be used on?

Once you have this information, open the Machine Reference Guide above. The machine manufacturers are listed in alphabetical order. Once your brand of machine is found, continue down until you find the correct model. By reading across, you can then determine the correct clutch plate required for your specific machine. Clutch plates are sold separately, so don't forget to add the one you need before checking out. Disregard the "brush sizes" and "pad driver sizes listed in the reference guide, they are for other applications. If possible, please include your machine make and model in the "Machine / Tool Notes" section of the order form. This is not required, but it is very helpful to our technicians when assembling your new tool.

2. What diameter tool do you need?

For most Diamabrush applications, the tool block diameter should be ordered 2" smaller than the stated machine size if you wish for the tool to fit up inside the housing of the machine. If you wish for your new tool to extend all the way to the edge of your machine housing, you will need a riser to allow the desired diameter tool to drop below the housing and extend outwards toward or past the edge of the machine housing. A riser is a just a simple spacer that is mounted between the clutch plate and tool. You will have the option of including a riser when you select your required clutch plate.

Either way is acceptable and there are pros and cons to each. A tool that fits up inside the machine housing, without a riser allows for a much lower center of gravity and also makes the tool much less vulnerable to damage. On the other hand, a riser allows for a larger tool that will cover more area and allows you to grind all the way up against walls and other stationary objects. We personally always recommend ordering your tool 2 inches smaller than the stated size of your machine and installing it without a riser, but the choice is up to you to decide which setup is best for your application. If you do choose to use a riser and order a larger tool, be very careful not to allow the diamond blades to impact stationary objects.

4. What center hole diameter is required?

Diamabrush Tools are available with a variety of different diameter center holes, as well as with no hole at all. Once again, the specifications for center hole sizes can be found in the Machine Reference Guide. The majority of machines on the market today require a standard 5" diameter center hole for mounting of the standard NP-9200 clutch plate. If you need a different, or specific size center hole, or desire a solid tool with no center hole, be sure to include that information in the "Machine / Tool Notes" section of the order form.
