The Mini Cup wheels are designed for grinding in corners or small spaces.
Both types are M14 thread, so fit on most angle grinders.
For fast and smooth working performance on hard concrete, with easy grinding on edges or corners.
Available in 50mm and 75mm cup or 70mm segmented.
Medium grit - #30/#40 grit.
Ensure small cup wheel is compatible with your grinder (ie grinder will be what hits wall first).
Spiral diamond grinding wheels are for general grinding with.
Fewer segments grind faster, but more segments suits softer concrete and will give longer life.
Turbo diamond grinding wheels are for aggressive grinding of masonry and concrete.
The 24 segment turbo wheels are less aggressive than the 12 segment wheels, and will last longer, but have a higher initial price. Usually do not leave marks.
Arrow cup wheels have a segment with a sharp leading edge for slicing, grinding and scrapping at the same time. Along with their coarse diamonds, this makes them aggressive, and ideal for glue removal and quick removal of thick layers. Used for general grinding as well as adhesive, epoxy and paint removal.
Rhomboid cup wheels are designed to remove glue, mastic and paint from soft or abrasive concrete.
They have an aggressive segment design, which provides fast grinding.
Although the segment is smaller than normal cup wheels, these cup wheels can provide fast grinding speed and outstanding performance.
More segments means the cup wheel will last longer, but will have a higher initial price.
Double row cup wheels are designed for general purpose grinding, and removal of imperfections and concrete bumps. They may leave marks on the concrete.
The double row gives them a smoother finish and a very long life.
Single row cup wheels are more aggressive.
Spiky cup wheel is for grinding on concrete and terrazzo floor, with good performance on hard concrete. It is also for paint, bitumen, carpet and glue residues and thin epoxy removal. These wheels are very smooth to use, cut very well, and leave no swirl marks if used correctly.

A Guide to Concrete Grinding:
While this introduction is basic only, it does give you a few ideas and considerations in regards to grinding concrete.
Concrete grinding is the process of removing high points, contaminants, and loose material from a concrete surface using a grinding machine. When grinding concrete, the bond of the diamond cup wheels should normally be the opposite of the concrete, ie use a soft bond on hard concrete, and a hard bond on soft concrete.
Use a larger diamond grit (lower number) for faster removal of concrete and for harder concrete.
If you mis-match, the results will be poor. A hard bond with hard concrete will not grind, whereas a soft bond on soft concrete will wear out the cup wheel prematurely.
It is hard to guess the hardness of concrete. We suggest you start with a hard bond (for soft concrete).
If it is not cutting, or is very slow, try a softer bond.
Grinding hard concrete does not produce much dust, and it is usually soft and non abrasive. The diamonds cut, blunt and break as normal, but the metal bond surrounding them is not worn away easily without the dust, so the diamonds are not exposed as much as with soft concrete. The diamond segment glazes over and stops working and rubs on the floor instead of cutting it. You can use larger diamonds (around #20 grit) or a softer bond to increase dust production. Also, reduce the surface area with fewer segments to increase the weight per square centimetre.
Grinding soft concrete usually produces sufficient gritty, abrasive dust that will wear away the bond and expose the diamonds adequately. In fact, too much dust can cause the grinding wheel to wear too fast, so vacuum up excess dust. Reduce the weight on the wheel or increase the surface area with more segments to reduce the weight per square centimetre.
Inspect your grinding discs regularly to make sure diamonds are exposed adequately and that it is not overheating.
Even the best discs will perform badly if used in the wrong application.
4 steps to grinding a concrete floor
- The bond is the material that initially holds the diamonds in place, but also wears away to expose the diamonds. A hard bond is best when dealing with abrasive material like soft concrete or rain-damaged pavement. Medium bond tends to perform poorly with hard materials, but wears away more quickly on abrasive materials. Soft bonds are ideal on hard materials because it wears away quickly, exposing a layer of diamond to grind the surface.
- Grit is the diamond size in the bond, and ranges from coarse to fine. Start with a coarse grit (#16-25 grit) to remove the uneven areas. Double the grit size with each stage, gradually breaking down the surface irregularities until the surface is sufficiently smooth.
- The shape of the diamond segments used has an impact too. Arrow heads have sharp leading edges for slicing and are effective for glue removal. Square segments have a long leading edge, so are ideal on uneven concrete. Round headed diamonds have a subtle leading edge so are perfect for working with finer grits.
- Number of segments - the more segments reduces pressure, whereas less increases pressure per segment.
The weight on the machine can affect the wear and tear on the machine, as well as effectiveness of grinding. Heavier pressure is more aggressive on the surface, where as lighter pressure is less aggressive.
Tips:
Dampening the concrete before grinding, or even spraying a little water may assist with your job ( be careful mixing water with electricity - use an RCD). It will make a grinding paste.
Similarly, clean builders sand on the surface, or reducing dust extraction, will help the grinding process.
A grinding compound such as Worx+ Totally Cut Sikk can assist grinding.
Do not let cup wheels get too hot. Over heating will cause the cup wheels to glaze over.
If cup wheels glaze up, adding clean builders sand to the surface can open up the segments again.
For tips on using cub grinders see the bottom of this page.
Remember - every job is different. The enormous combinations of different types of surfaces, different cup wheel styles, with many different bonds and grits, plus different machines and varied operator experience means it is impossible to guess what will give the perfect result the first time. Some experimentation is often necessary to achieve the required results.
Note - If you are cutting dry, always be aware of the danger of breathing in the dust. Ensure a dust extraction system is used with a suitable filter fitted. Use a half face respirator or a PAPR (Powered air purifying respirator). Even if you are cutting wet, the slurry created can dry out and create a hazard for other users - dispose of slurry as per your local regulations.

Diamond cup wheels are diamond tools bonded with metal and diamond segments welded along a pressed metal wheel body, which appears in a cup shape. These cup wheels are suitable for breaking down heavy building materials like concrete, granite, and marble.
Diamond Cup Wheels are designed for various tasks such as:
Cup wheels with multiple large diamond segments are used for heavy-duty jobs, including grinding of stone and concrete
The smaller and lesser segment cup wheels are used to remove paints, glues, mastics, etc.
Different variants require to be considered when using Diamond cup wheel, including the various diamond grits, the standard of the diamond segments. Therefore the diamond concentration to it most accurately fits different surface types. For instance, when grinding harder surfaces, contractors need to use a softer bond segment. Once they are grinding more delicate surfaces, they have to use a more rigid bond segment. It is often an incredibly important factor to know during surface preparation. Each cup wheel is specifically designed for grinding different building materials.
Choosing the proper diamond cup wheel can cause a severe headache even to the foremost experienced supplier or end-user. It's because a diamond cup wheel, like every other diamond manufacturing equipment, is suitable for various applications.
However, no matter what you plan to use this must-have equipment for, following the ideas during this article can prevent tons of stress and stop wasting your money on a tool that won't offer you the result we desire.
These are a number of the factors you want to put into consideration when selecting diamond cup wheels. These include:
Selecting the Appropriate Diamond Cup Wheel Category
The diamond cup wheel comes in variants of different specifications. According to the application type, the cup wheel category is selected. For example, heavy loads like concrete and grinding stone would require a diamond wheel cup with a huge diamond segment. On the opposite hand, smaller diamond segments fit perfectly for lighter works, including glues, paints, epoxy, and other surface coatings. Therefore, it's imperative first to work out the character of the task ahead.
Understand Surface Hardness
Depending on the hardness of the surface, the diamond cup wheel generally exists in two phases.
Phase 1 consists of coarse grinding. In this phase, diamonds possess a high propensity to become blunt. It occurs because a diamond cup wheel quickly blunts out when operating on hard surfaces. Thus, a soft diamond bond with high diamond highness is suitable for this phase.
Phase 2 involves fine grinding or polishing. It requires the utilization of a tough bond thanks to its superior precision. However, as a diamond doesn't disintegrate quickly, a soft diamond will do the work briefly. Grit between 80 to 120 is right at this phase, while the concentration must be set high.
Identify the Proper Abrasive Components
The diamond cup wheel has two significant parts- the cut of abrasive grains and the bond between abrasive grains. The mixture of the grain, bond, and therefore the spacing between the wheel form the structure. You want to consider the share also. The precise abrasive that a cutting wheel uses mostly depends on its interaction with the work material.
A perfect abrasive self maintains itself through automatically sharpening. The abrasive fracture works by establishing new cutting points when dulling set in. However, there's a particular feature for every abrasive type in terms of strength, hardness, resistance to impact, and fracture toughness.
Abrasives are available in three primary forms. It includes alumina, zirconia alumina, and carbide.
Check The Grit Size
Every diamond cup disc comes with a variety that showcases its characteristics. It represents the dimensions of the precise abrasive grains that the wheel carries. To work out the grit size, you've got to count the number of openings per linear inch. You'll find this within the final screen size. Coarse grains have numbers like 10, 16, and 24. Coarse grain indicates that the dimensions of the fabric the tool removed are large. Grit wheels range between 70, 100, and 180 and useful in making fine grit wheels. They're also ideal for fine finishes, tiny contact areas, and valuable materials with high brittleness.
Know the Various Diamond Cup Wheel Shapes
Although all Diamond Cup Grinder may appear as if they're straight once you view the image, they are available during a wide selection of shapes. Some have a hollow center that permits them to suit into machines spindle flange assembly. Others include cylinders and dish wheels that even have different shapes. Some mounted wheels also are available in cone or plug shapes. They're suitable for off-hand and grinding jobs that need high precision.
Choose the Proper Bond
You need the right bond for your wheel to run efficiently. Bonds are materials that bind abrasive grains to stop them from falling apart and run effectively. Bonds, like abrasive grains, also wears away with frequent use. The first bonds that are in use in diamond cup discs are vitrified and organic bonds. Each has its unique strengths and weaknesses. As an example, vitrified bonds are both challenging and brittle. Also, they provide resistance to acid, oil, water, and temperature.
Organic bonds exist in several forms, like resinoid and rubber. Organic bonds are ideal to be used in fabrication industries for diamonds and also for sharpening saws.
Customization
It is a choice you want to make. The web offers a good range of diamond cup wheels. While many of them live to their billings, unfortunately, most are well packaged junks, which will not provide the desired result. Instead, it's advisable to travel for a customized diamond cup wheel. Besides that, they give the most exact value for money; you'll freely customize the specifications consistent with your needs. Also, with a customized cup wheel, you'll successfully eliminate guess works.
These are tools useful for grinding the dry concrete surface and smoothen other materials, including diamond. Best Diamond Cup Wheel offer more aggressive removal than conventional abrasives.
While you'll easily and quickly purchase ready-made 7" diamond cup wheel and other diamond cutting tools in e-commerce stores, none can offer you the freedom of getting the precise specification you would like for a selected application. Thus, going for customized diamond cup wheels may be smarter for diamond tools distributors, suppliers, and end-users alike.
