3M™ Cloth Belt 361F, 220 XF-weight, 4 in x 156 in, Sine-lok 45° Angle, Precision Roll Grinding, 50 ea/Case

3M™ Cloth Belt 361F comes with fast-cutting aluminum oxide abrasive grains bonded to heavy polyester cloth backing. Its durable, heat-resistant resin supports both wet and dry applications. Grades of P100 and lower are backed with YF-weight polyester, and grades higher than P100 are backed with slightly less stiff XF-weight polyester.

Aluminum oxide mineral is a popular choice among industrial professionals because of its cut-rate, durability, and long life. It can be used on a wide variety of materials in both woodworking and metalworking, including ferrous alloys, and is the most commonly used industrial abrasive. The abrasive particles are adhered to the cloth backing with resin, creating a strong bond that withstands high heat and pressure.

Abrasive belts come in many different widths and lengths and are used on a variety of belt sanding tools for many different metalworking applications. 3M offers a broad selection of belts to fit most any industrial belt sander. Wider belts are designed for wide belt sanders for flat finishing—to smooth rough cut edges of metal sheets, or add a grain pattern to stainless steel sheets. Medium-width belts are generally used on a backstand for weld removal or on a feed -thru style flat finisher for imparting a finish on sheets or coils. Narrow belts can be used on backstands for grinding and finishing, or on file tools for for finishing in right angle corners.
