The 3M Cubitron 3 Depressed Centre Grinding Wheel is an exceptionally fast-cutting and long-lasting rigid-bonded wheel for heavy weld removal and other heavy-duty grinding applications. Using a depressed centre to enable grinding at any angle, this wheel works well on almost all materials while being specially formulated for use on stainless steel, mild steel, and aerospace alloys. Additionally, the 3M Cubitron 3 Depressed Centre Grinding Wheel is powered by 3M Re-Engineered Precision Shaped Grain using proprietary breakthroughs in molecular bonding technology designed with sharp, angular structures that continuously fracture to form sharp points. These clean, sharp points help create an abrasive that slices faster, runs cooler, and lasts much longer than conventional abrasives. 3M Cubitron Performance Abrasives are made for professionals who need more from their equipment — so experience the next generation in abrasive performance by choosing the 3M Cubitron 3 Depressed Centre Grinding Wheel.
