Grinding wheel Metabo 616660000 for Concrete Stone 18 cm 8500 RPM

The Metabo 616660000 grinding wheel for concrete and stone is a 180 mm diameter abrasive disc engineered for medium to heavy material removal on masonry, concrete and natural stone. With a maximum rotational speed of 8,500 RPM, a 22.2 mm bore and a 6 mm thickness, this wheel balances cutting aggressiveness and stability for use with standard angle grinders. Each pack includes ten discs to provide a continuous supply for jobsite and workshop applications.

Advantages

This grinding wheel offers consistent abrasive performance on concrete and stone surfaces while maintaining dimensional stability during use. The 180 mm diameter provides a broad working surface for efficient material removal, and the 6 mm thickness helps resist warping at typical operating speeds. The 22.2 mm bore matches common flange sizes for safe mounting on compatible angle grinders. A pack of ten ensures reduced downtime for replacement and better value for repetitive tasks.

Suitable for

• Surface grinding and leveling of concrete floors and slabs
• Removing mortar, grout and surface contaminants from masonry
• Shaping and smoothing natural stone and architectural elements
• Preparation of substrates before coating, sealing or bonding

How to use

Fit the grinding wheel onto a compatible angle grinder with a 22.2 mm arbor, ensuring the wheel is mounted in the correct direction and secured by the flange and nut according to the grinder manufacturer’s instructions. Operate the grinder at or below the specified maximum speed of 8,500 RPM. Apply steady, even pressure and move the wheel across the work surface to achieve uniform material removal; avoid excessive force that could overload the wheel or the tool. Replace the wheel once abrasive performance is reduced or if any cracks, chips or other damage are observed.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection, gloves and respiratory protection when grinding concrete or stone. Ensure the workpiece is secure and allow the wheel to reach full speed before contacting the surface. Follow dust-control practices such as wet grinding or local extraction where required to minimize respirable silica exposure.
