Description

Our 3M™ microfinishing film belt 372L is designed to help you get the finest finish possible and is available in a wide variety of forms. It features micron graded aluminum oxide abrasive bonded to a durable polyester film backing to produce a fast cut rate and uniform finish on composites, plastic, fiberglass and metal. The 5 mil polyester film backing offers stretch resistance, high unit pressure on the material, compatibility with most coolants and suitability for a wide variety of wet and dry applications. 3M™ microfinishing film belt 372L is manufactured with a closed coat abrasive surface to increase efficiency and produce a finer finish. Microfinishing film belt 372L features precision, micron graded aluminum oxide, which is a popular choice among industrial professionals because of its fast cut rate and fine finish. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges. Due to its fast cut-rate, hardness, and strength, it is widely used for sanding and finishing applications.
