## Description

This cup-style diamond grinding wheel set is designed for handheld or stationary grinders and uses four in. wheels with a 0.86 in. arbor. Each wheel features large, heat-treated grinding segments intended to resist heat buildup during extended cutting and to maintain a consistent cut across hard materials. The diamond grains provide durability for grinding concrete, marble, tile, and natural stone, helping to smooth rough faces, blend edges, and remove thin coatings without excessive wear. The cup shape offers a wide cutting surface and efficient material removal while maintaining balance during rotation, which helps reduce vibration. The wheels are suitable for dry grinding to reduce dust and wet grinding to improve dust control and cooling, depending on the task and grinder setup. A five-piece set provides multiple options for varying levels of material removal and surface finish, making it useful for remodeling, resurfacing, and preparation work. Users should verify grinder compatibility with the 0.86 in. arbor and follow safety guidelines, including securing the wheel and wearing appropriate PPE. Proper mounting and progressive feeding techniques help optimize performance and extend wheel life on hard substrates. The set is intended for projects that require steady finish along with efficient material removal and controlled results.

• Cup-shaped diamond wheel design for efficient material removal
