The 125mm (5") L-Shaped Diamond Grinding Wheel is engineered for fast and efficient grinding of concrete, granite, natural stone, masonry, and other hard construction materials. Designed for professional contractors and tradespeople, this cup wheel combines aggressive cutting performance with excellent durability to help reduce grinding time on demanding surface preparation projects. The specialised L-shaped diamond segments concentrate grinding pressure for rapid material removal while maintaining smooth operation and improved balance. This design helps remove high spots, surface imperfections, and uneven areas more efficiently than conventional grinding wheels. Built with high-quality diamond segments, the wheel offers an extended working life and consistent grinding performance across a wide range of applications. Improved dust management also helps create a cleaner working environment when used with suitable dust extraction equipment. Suitable for both wet and dry grinding applications, this 30-grit cup wheel is ideal for surface preparation, concrete levelling, stone shaping, and general grinding work. The standard 22.23mm bore ensures compatibility with most 125mm angle grinders used throughout the construction and flooring industries.
