Professional Grinding Wheel This conical grinding wheel is made of quality emery and silicon carbide and is designed for M10 thread angle grinders. It is available in 38mm and 50mm sizes and is suitable for chamfering, grinding, and finishing various stone surfaces with precision and ease. Smooth Finishing The beveled edge design helps create a smooth, end finish on glass and porcelain tiles, reducing rough edges and enhancing the overall appearance of tiling projects for a polished, professional look. Crack Reduction Technology This grinding wheel is specially engineered to relieve stress around rough holes in tiles, significantly reducing the risk of cracking in both standard and large format tiles that are subjected to tension during installation or use. Enhanced Edge Quality With its precisiongrinding capabilities, this tool greatly improves the edge finishing of exposed holes in tiles and stone, creating clean, professionallooking results for home improvement or construction projects. Use scenarios Chamfer and finish around M10 threaded holes in stone and tile installations to achieve clean, consistent openings and smooth edges. Bevel and finish edges on glass or porcelain tiles after drilling holes to minimize sharp edges and improve overall tile appearance. Use on largeformat tiles or stone surfaces near openings to reduce edge stress and the likelihood of cracking during installation or use, while achieving a quality edge finish.
