Concrete/ Masonry Grinding Wheels

A masonry grinding wheel is a type of abrasive wheel that is used for grinding and cutting hard materials such as concrete, stone, brick, and granite. Masonry grinding wheels typically contain silicon carbide grains that are sharp and penetrate the surface of the workpiece. Masonry grinding wheels can have different shapes and sizes, such as type 27 wheels with a flat profile and a depressed center, or type 28 wheels with a concave or saucer-shaped design. Masonry grinding wheels are designed to provide aggressive grinding action and smooth-running performance.

• Diamond-Segmented wheels, which have different grit levels from fine to coarse and are suitable for grinding hard materials.
• Silicone-Carbide stones, which are a cost-effective way of grinding concrete surfaces from fine to coarse finishing.
• Tungsten-Carbide wheels, which are the most expensive ones and perform using carbide-tipped blocks and beveled edges.
• Type 1 Snagging wheels, which have a straight profile and a small diameter of about 2 to 4 inches and are ideal for grinding off excess metal.
• Type 27 Grinding wheels, which have a flat profile with a depressed center and allow for a range of grinding angles, typically from 0 to 45 degrees.
• Type 28 Grinding wheels, which have a concave or saucer-shaped design and allow for better access to the workpiece and increased aggression at low grinding angles, typically from 0 to 15 degrees.

• Use the right wheel for the right material. Different types of concrete grinding wheels are designed for different types of materials, such as concrete, brick, stone, etc. Using the wrong wheel for the wrong material can cause the wheel to wear out faster or damage the material.
• Use proper lubrication when grinding concrete. Lubrication helps to reduce friction and heat, which can cause the wheel to glaze over or lose its sharpness. Lubrication also improves the quality of the grind and the life of the wheel.
• Dress the wheel regularly. Dressing the wheel means removing the glazed or dull layer of abrasive grains on the edge of the wheel and exposing a fresh layer of sharp grains. This can be done by grinding into a hard material, such as a dressing stick or a grinding wheel, for a few seconds. Dressing the wheel can restore its grinding performance and extend its life.
• Clean the wheel properly after each use. You should clean the wheel with a soft brush and a gentle solvent to remove any dirt or debris that may have accumulated on the wheel. This can prevent corrosion and rust, which can affect the quality and life of the wheel.
