The 3M™ Cubitron™ 3 Depressed Center Grinding Wheel is an exceptionally fast-cutting and long-lasting rigid-bonded wheel for heavy weld removal and other heavy-duty grinding applications. Utilizing a depressed center 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 Center Grinding Wheel is powered by 3M Re-Engineered Precision Shaped Grain, a breakthrough proprietary 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 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 Center Grinding Wheel.

The 3M™ Cubitron™ 3 Depressed Center Grinding Wheel’s next-generation performance is backed by over 100 years of 3M metalworking innovation. Like other 3M industrial abrasives, this wheel is built to withstand a variety of applications, including grinding on the toughest metals. It's also designed to perform better as it runs faster, so having a tool able to maintain speed is critical. Unlock its fullest potential by pairing it with a powerful and long-lasting 3M Angle Grinder for enhanced performance and durability in harsh industrial conditions; always remember to use a tool guard and not exceed the maximum operating speed listed on the wheel. 3M has what you need to equip your team with industry-leading solutions, meaning you and your team will be prepared for whatever challenge comes your way.
