Description
The 3M 7000045139 Cubitron II 984F ceramic belt is built for demanding metalworking tasks where fast, dependable material removal matters. With a compact ½ ½-inch width and 18 inch overall length, it fits manual backstands, file belt sanders and tight‑space finishing setups. Precision‑shaped ceramic grains deliver continuous, sharp cutting edges that stay productive far longer than typical abrasives. Rated 36+ grit, this belt aggressively removes stock on cobalt, nickel alloys, brass, titanium and stainless steel while keeping finish control. A YF‑weight polyester cloth backing stabilizes the belt under pressure, adding tear resistance for repeated polishing or grinding passes. Closed‑coat construction maximizes abrasive coverage, providing predictable performance on high‑value substrates and heavy‑duty workflows. Single‑flex form makes the belt compatible with a wide variety of small grinders and manual finishing tools without complex setup changes. The Fabri‑Lok splice offers a robust, low‑profile joint that reduces downtime from splice failures during continuous use. This belt supports wet or dry applications increasing versatility across different equipment and coolant strategies. Choose 3M 7000045139 when you need a narrow, high‑cut, long‑life 3M cubitron 984F II ceramic belt for precision finishing, deburring, and surface prep.
Product Features and Benefits
