Grinder Discs for Surface Preparation & Material Removal

Grinder Discs are used with compatible grinders for surface preparation, material removal, grinding, shaping, and leveling on concrete, masonry, tile substrates, natural stone, and other approved materials. Available products include diamond grinding wheels, cup wheels, coating removal discs, metal bond grinding wheels, and specialty discs for applications such as thinset removal, adhesive removal, and lippage correction. Disc construction, diameter, bond, mounting system, and material compatibility vary by product.

Types of Grinder Discs

Diamond Grinding Wheels & Cup Wheels

Diamond grinding wheels and cup wheels are designed for grinding and removing compatible concrete, masonry, stone, and other hard materials. Different segment configurations and bond characteristics provide varying levels of material removal and surface refinement depending on the application.

Coating & Adhesive Removal Discs

Specialty removal discs are available for stripping compatible adhesives, coatings, thinset mortar, and other surface buildup. The appropriate disc depends on the material being removed, underlying substrate, and desired surface condition.

Lippage & Shaping Discs

Compatible grinding and shaping discs can be used for controlled edge shaping, surface refinement, and lippage correction on appropriate tile and stone materials. Disc profile and abrasive characteristics should be matched to the material and required finish.

Choosing the Right Grinder Disc

Choose grinder discs according to the material, required removal rate, grinding or shaping application, desired surface finish, disc diameter, arbor or mounting system, and grinder speed. Verify that the selected disc is rated for the grinder and intended operating conditions.
