Tough Durability for Coarse Grinding3M™ Cloth Belt 461F is frequently used for coarse grade grinding on stainless steel and titanium, as well as for glass polishing. The heavy polyester cloth backing provides rugged durability and tear-resistance, and is suitable for wet or dry applications. Belts come in both YF-weight polyester and XF-weight polyester.Superior Finish Sanding with Silicon CarbideSilicon carbide is a very hard and sharp mineral commonly used for low-pressure applications such as paint prep and the final stages of whitewood sanding, as well as grinding applications on metal. It can also be used for glass and mirror grinding, finishing, and polishing. While it may have a shorter life than aluminum oxide, it produces a superior finish and should be used where the best possible finish is desired.Belt Sizes for Every ApplicationAbrasive belts come in many different widths and lengths and are used on a variety of different belt sanding tools for many different applications on both wood and metal. At 3M we offer a broad selection of belts to fit most any industrial belt sander. Wider belts are used with wide belt sanders to dimension or finish wood panels, smooth rough cut edges of metal sheets, or add a grain pattern to stainless steel sheets. Medium-width belts fit onto edge sanders for sanding flat, narrow surfaces such as panel edges; and narrow belts are used with portable belt sanders for sanding or blending wood pieces such as cabinet doors.
