Concrete/ Masonry Cutt-Off Wheels

A concrete cut-off wheel is a type of abrasive wheel that can cut through concrete and other masonry materials using a forward motion. Concrete cut-off wheels are made by bonding abrasive particles, such as silicon carbide or diamond, together with resin. Concrete cut-off wheels are thick enough to withstand the abrasive nature of concrete and rigid enough to maintain their shape and size.

Concrete cut-off wheels can be fitted to various power tools, such as angle grinders, straight grinders, chop saws, etc., depending on the size and shape of the wheel and the material being cut. Concrete cut-off wheels come in different diameters, thicknesses, and types, depending on the type of material and cut you want to achieve.

• Type 1 wheels, which have a flat shape and are used for straight cutting on flat surfaces.
• Type 27 wheels, which have a depressed center and are used for cutting and light grinding on angled surfaces.
• Type 41 wheels, which have a flat shape with a reinforced center and are used for heavy-duty cutting on flat surfaces
• Type 42 wheels, which have a depressed center with a reinforced center and are used for heavy-duty cutting and light grinding on angled surfaces.

• Use proper lubrication when cutting masonry materials. 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 cut 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 cutting it into a hard material, such as a grinding wheel or a dressing stick, for a few seconds. Dressing the wheel can restore its cutting 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.
