The 125mm (5") Double Row Diamond Grinding Cup Wheel is engineered for professional surface preparation, concrete grinding, and material removal applications. Designed with 20 industrial-grade diamond segments arranged in a double-row configuration, this cup wheel provides aggressive cutting performance while maintaining excellent stability and control during operation. The double-row segment layout increases surface contact and improves load distribution, allowing the wheel to remove material quickly while reducing vibration and uneven wear. This design helps deliver smoother grinding performance and extended tool life compared to many single-row alternatives, making it an excellent choice for demanding construction and flooring projects. Suitable for grinding concrete, stone, brick, and masonry surfaces, this cup wheel is commonly used for levelling uneven floors, removing surface imperfections, preparing concrete prior to coatings or polishing, and eliminating light adhesives, paints, and surface contamination. The reinforced steel body and premium diamond segments are built to withstand heavy workloads while maintaining consistent grinding performance throughout the life of the tool. Designed for use in both wet and dry grinding applications, the wheel offers flexibility across a wide range of job-site conditions. Compatible with most standard 125mm angle grinders featuring a 22.23mm bore, it provides contractors, concreters, builders, and surface preparation specialists with a reliable and cost-effective grinding solution. Whether you're preparing a concrete floor for polishing, removing high spots, smoothing rough surfaces, or carrying out general surface preparation work, this double-row diamond cup wheel delivers the durability, efficiency, and performance required for professional results.
