3M™ Cloth 440D is an abrasive sanding belt constructed on a flexible, X-weight cloth backing that features open coat construction for greater load resistance. The silicon carbide abrasive and flexible backing make this cloth an ideal product for dry applications such as surface dimensioning and defect removal.

3M™ Cloth Belt 440D
Silicon Carbide is a hard mineral, yet fractures easily to provide a sharp edge
Flexible Sanding Cloth
Our 3M™ Cloth Belt 440D is best suited for metal sanding and finishing thanks to its durability and fast cutting abrasive material. With a flexible cotton, this X-weight cloth backing provides smooth operation and durability and can conform to the shape of contoured parts for consistent finishing. The abrasive side features an open coat of silicon carbide grains to provide a fast cut and a fine finish.

Silicon Carbide Abrasive
This belt uses silicon carbide, which is a popular choice among industrial professionals because of its fast cut-rate and smooth finish. This synthetic mineral is very hard and fractures easily, resulting in freshly exposed sharp edges that cut extra fast and produce a smooth, professional-looking finish. Silicon carbide products are commonly used for low-pressure applications such as cleaning and finishing on wood and metal. While it wears faster than aluminum oxide, it produces a consistent superior finish.

Belt also uses a resin bonding which is specially designed to resist thermal and chemical deterioration
Heat and Load Resistant
This belt 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 faster sanding and a higher cut rate. Open coat construction means the abrasive grains are placed with space between them to help evacuate sawdust and other sanding 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 sanding ability.
