Diamond grinding segments are specialized tools designed to level and prepare concrete floors for various projects. These powerful grinding shoes consist of a steel plate with one or two diamond segments attached. The segments are made from a careful mixture of metal powder and diamond grains, giving them their impressive cutting ability.
Our concrete grinding segments come in various bond types to match different concrete hardness levels. Remember this simple rule: hard concrete needs soft bond grinding shoes, while soft concrete requires hard bond grinding shoes. Choosing the right match prevents premature wear and ensures optimal performance.
Available bond types include:
Our diamond grinding shoes also come in multiple grit sizes ranging from coarse 8/10# to fine 120/140#, letting you progress from rough grinding to smooth finishing on any concrete surface.
These concrete grinding segments are compatible with all major floor grinding machines including Husqvarna, Scanmaskin, Blastrac, Lavina, and HTC models, making them versatile additions to your toolbox.
Whether you're preparing floors for a nuclear plant, bridge, road project, or simple parking lot, our diamond grinding shoes deliver reliable performance that professionals count on. Test the concrete hardness first, select the appropriate bond type, and experience the difference quality grinding diamonds make in your concrete preparation projects.
Application Chart
We supply Redilock Diamond shoe with 5 metal bond types which can cover the concrete hardness from extra soft up to extra hard. It is essential to choose the right bond types for the grinding job. If the concrete floor is hard, the grinding shoe bond should be soft, however, if choose the hard bond, then the diamond segments of the grinding shoe will get burned easily after short time using and the grinding shoe will become plished. Before choosing the bond types, it is necessary to find the concrete hardness first. Below are some information for your reference.| Concrete Hardness | Mpa | Typical Application |
| Very Hard | 60Mps or More | Nuclear Plants |
| Hard | 40Mpa to 55Mpa | Bridges, Piers |
| Medium | 28Mpa to 40Mpa | Roads |
| Soft | 20Mpa or less | Sidewalks, Patios, Parking lots |
After we know how to classify the hardness of concrete, we will how to choose the right grinding cup wheels or grinding shoe, see the below table
| Concrete Hardness | Mpa | Bond Types |
| Very Hard | 60Mps or More | Very Soft |
| Hard | 40Mpa to 55 Mpa | soft |
| Medium | 28Mpa to 40Mpa | Medium |
| Soft | 20Mpa or Less | Hard |
Test your concrete hardness first. For hard concrete (40-55 MPa), use soft bond grinding shoes. For soft concrete (20 MPa or less), use hard bond grinding shoes. The general rule is: hard concrete needs soft bonds, soft concrete needs hard bonds.
Using the wrong bond type can cause the diamond segments to burn out quickly. If you use hard bond segments on hard concrete, they'll become polished and ineffective after a short time, wasting your investment and time.
Common grit sizes range from coarse to fine: 8/10#, 14/16#, 16/18#, 20/25#, 30/40#, 50/60#, 80/100#, and 120/140#. Start with coarser grits for initial grinding, then progress to finer grits for finishing.
For rough concrete with coatings or major surface issues, start with coarser grits (8/10# or 14/16#). For concrete that's already relatively smooth or for fine finishing work, use medium to fine grits (50/60# and above).
Diamond grinding segments are made to fit specific floor grinder models. Check compatibility with your machine brand (Husqvarna, Scanmaskin, Blastrac, Lavina, HTC, etc.) before purchasing.
Lifespan varies based on concrete hardness, bond type match, and operating conditions. When properly matched to the concrete, grinding segments can cover hundreds of square feet before replacement is needed.
No, these tasks usually require different tools. Coating removal typically needs coarser, more aggressive segments, while polishing requires a progression from medium to fine grit segments.
Professional concrete testing equipment (like Schmidt hammers) can measure concrete in MPa. For smaller projects, you can do a simple scratch test with a nail or awl - harder concrete is more difficult to scratch.
Single-segment grinding shoes have one diamond segment attached to the steel plate, while double-segment shoes have two. Double-segment designs often provide more grinding coverage and can be more efficient for larger areas.
Replace grinding segments when you notice significantly decreased cutting efficiency, visible wear on the diamond segments, or when the diamonds become flush with the metal bond (showing no protruding diamonds). Using worn segments reduces productivity and can damage your floor grinder.
