3M Cubitron II Cloth Belt 984 Industrial Precision-Shaped Grain Abrasive Belt for Metalworking
The 3M™ Cubitron™ II Cloth Belt 984F offers revolutionary performance secrets for industrial metalworking applications. Engineered with 3M’s proprietary Precision-Shaped Grain (PSG) technology, this heavy-duty abrasive sanding belt raises the bar for cutting speed, cool operation, and service life. It features a robust, water-resistant Y-weight polyester cloth backing, making it the premier choice for medium to high-pressure grinding environments including automatic robotic lines, backstand grinders, and cylindrical belt machinery.
Unlike conventional ceramic abrasives that fracture into irregular shapes and "plow" through metal surfaces—generating excessive frictional heat—the triangular PSG micro-crystalline structure continuously fractures into razor-sharp edges. This delivers a true slicing action, ensuring unparalleled stock removal while preventing burning, tempering, or discoloration on heat-sensitive metals like stainless steel, nickel alloys, and titanium.
Key Features & Engineering Advantages
-
3M™ Precision-Shaped Grain (PSG) Technology: Delivers up to 2x the cut rate and outlasts conventional ceramic abrasives by up to 4 times, maximizing your workshop throughput and reducing belt changeover downtime.
-
Integrated Grinding Aid (Cooling Coating): Specially formulated with a top-coat grinding aid to minimize heat buildup, prevent thermal damage, and protect structural integrity during extreme aggressive friction on exotic alloys.
-
Extra-Heavy Y-Weight Polyester Backing: The rugged, waterproof polyester cloth backing provides exceptional tensile strength, edge durability, and tear resistance under high-pressure mechanical grinding.
-
Optimized for Wet & Dry Grinding: Designed to excel in both dry and lubricated environments, preventing belt slippage or degradation.
-
Engineered Self-Sharpening Mechanics: As the triangular grains fracture during operation, they expose new, pristine cutting points to preserve peak grinding efficiency from first contact to final use.
