3M™ Cloth Roll 440D is used to create rolls and belts for metal finishing and stock removal. It is made with a flexible, x-weight cloth backing and features open coat construction for sanding and finishing applications on all metals. The silicon carbide abrasive and flexible backing make this cloth an ideal product for dry applications such as surface dimensioning and defect removal.
Flexible and Fast Cutting Abrasives made with 3M™ Cloth Roll 440D are best suited for metal sanding and finishing thanks to its durability and fast cutting abrasive material. The x-weight, cotton cloth backing provides smooth operation and durability and can conform to the shape of contoured parts for a consistent finish. This cloth uses silicon carbide, which is a popular choice among industrial professionals because of its fast cut-rate and excellent finish. This synthetic mineral is very hard and fractures easily, resulting in freshly exposed sharp edges that cut extra fast and produce a professional-looking finish. Silicon carbide products are commonly used for low to medium-pressure applications such as cleaning and finishing on wood and metal. While it wears faster than aluminum oxide, it produces a superior finish.
Heat Resistant This cloth also uses a resin bonding which is specially designed to resist thermal and chemical deterioration, which can occur during sanding. This bond is very tough and excellent for precision work on hard and soft wood. This also allows for fast sanding and a consistent cut rate. With an open coat design the abrasive grains are placed with space between them to help evacuate debris and avoid clogging the cutting edge of the grains. This allows the abrasive mineral to continue cutting even when sanding materials that would otherwise clog the grain and hinder the grinding or finishing process.
