The 3M Cubitron 3 Cloth Belt is an essential abrasive for high-speed, heavy-duty grinding, deburring, and stock removal in fabrication and machining shops. This belt uses 3M’s proprietary Cubitron 3 precision-shaped grain technology, which cuts through metal faster and stays sharp longer than traditional abrasives, helping you complete jobs quicker and reducing the time spent changing belts.
- Extended Belt Life: The Cubitron 3 mineral is engineered to fracture into new sharp points as it wears, meaning you get a consistent, aggressive cut for a significantly longer period before needing a replacement.
- Consistent Cutting Speed: The 36+ grit abrasive maintains its aggressive cutting ability throughout the life of the belt, reducing heat buildup and minimizing the risk of metal discoloration or warping on heat-sensitive alloys.
- Durable Backing: Featuring a Fabri-Lok, single-flex cloth backing, this belt offers excellent strength and tear resistance, making it reliable for demanding, high-pressure applications without premature shredding.
Who this is best for: Fabricators, welders, and machine shops who need to remove significant amounts of material quickly and efficiently on stainless steel, carbon steel, and other hard metals, especially those utilizing 3/4 in wide portable or benchtop belt grinders.
