Grinding Disc Norton Clipper 200×20×32 mm A46NVS for Stone and Concrete

The Norton Clipper Grinding Disc 200×20×32 mm A46NVS is a diamond abrasive wheel designed for surface grinding of stone and concrete. It is intended for use on grinders that accept a 20 mm bore with a 32 mm adapter seat, delivering consistent material removal and a controlled finish. The A46NVS grit specification balances cutting speed and life for professional and renovation tasks where reliable abrasive performance is important.

Advantages

This grinding disc offers durable diamond abrasive composition for effective removal of mortar, thinset, and surface laitance on concrete and natural stone. The segmented or continuous rim design provides stable grinding performance and helps maintain a predictable rate of stock removal. Compatibility with a 20 mm bore and 32 mm adapter seat ensures straightforward mounting on commonly used angle grinders and floor grinders when adapters are employed. The A46NVS grit achieves a compromise between aggressive cutting and usable life for repeated on-site applications.

Suitable for

• Surface grinding and leveling of concrete floors and slabs
• Removing thinset, adhesive residues, and cementitious laitance
• Truing and smoothing natural stone surfaces
• Preparation of substrates before coating or epoxy application

Key specifications

• Diameter: 200 mm
• Bore diameter: 20 mm (fits with 32 mm adapter seat)
• Abrasive type: diamond
• Grit grade: A46NVS
• Application materials: stone and concrete

How to use

Mount the disc on a compatible grinder using the 20 mm bore and the appropriate 32 mm adapter seat if required, ensuring the disc is securely fastened according to the machine manufacturer's instructions. Operate the grinder at the recommended speed ratings for diamond grinding discs and use steady, controlled passes to achieve uniform material removal. Apply moderate pressure and allow the diamond segments to cut; avoid excessive force that could cause uneven wear or damage to the bond. Use proper dust extraction or wet methods where appropriate to reduce airborne dust and extend disc life.

Usage recommendations

Use suitable personal protective equipment including eye protection, hearing protection, respiratory protection, and gloves. Check the grinder's maximum speed rating and do not exceed the disc's recommended rpm. For best results on large areas, combine this disc with appropriate grinding pads and progressively finer grits to reach the desired surface finish.
