01｜Product Overview
3M 7447C industrial non-woven abrasive hand pad is a versatile general-purpose manual finishing abrasive consumable, compounded with high-quality aluminum oxide mineral abrasives inside the nylon non-woven fiber matrix. It supports both dry grinding and wet grinding operations, featuring soft and flexible texture that can be bent, folded or cut freely according to processing demands. It can be operated by hand directly, or matched with hand blocks, backing pads and portable sanders for auxiliary machining. This pad delivers gentle yet steady cutting power, avoiding overly aggressive material removal. It is widely adopted for surface conditioning in metal processing, woodworking and hardware industries, and can consistently finish surface cleaning, rust removal, oxide layer stripping, decorative grain brushing, burr removal and surface blending, to create uniform, delicate decorative textures on various substrate surfaces.
02｜Product Advantages
*It adopts an open mesh three-dimensional structure with abrasives evenly distributed throughout the fiber layer. It features self-sharpening grinding property, realizing continuous and stable cutting and effectively resisting loading and clogging during long-time grinding.
*Cool cutting design brings excellent heat dissipation performance, which can quickly dissipate frictional heat generated in grinding, preventing workpiece burn, discoloration and thermal deformation caused by high temperature.
*Elastic grinding mode enables controllable cutting force. It will not leave deep scratches or damage the base material, and will not change the original outline and dimensional tolerance of the workpiece.
*It has outstanding water and oil resistance. Even under wet or oily working conditions, it maintains consistent grinding performance. Its service life is longer, and the abrasive capacity stays stable after repeated processing.

| Size | 150mm×230mm |
| Grade | Very Fine A-VFN |
04｜Product Feature
*It is made of nylon non-woven base material with aluminum oxide grains, flexible and easy to fit curved surfaces and special-shaped grooves.
*Worn fibers fall off automatically to expose new abrasives continuously, keeping stable cutting force.
*It can be folded and cut freely, suitable for processing complex corners and hard-to-reach positions.
*It works under dry and wet conditions, replacing steel wool without rust risk.
05｜Wide Range of Applications
It is suitable for rust removal, oxide scale and old stain stripping on various metal workpieces including stainless steel, aluminum alloy and copper alloy. It can perform random grain brushing and decorative surface blending finishing on stainless steel sheet metal, motor plates and hardware fittings to form uniform brushed textures. It is also used for light deburring, weld seam cleaning and surface conditioning after welding. It can grind inner grooves, undercuts, special-shaped slots and other complex hidden positions that conventional abrasive tools are hard to reach. Besides metal processing, it applies to woodworking, door industry paint pre-treatment, paint surface polishing, as well as cleaning and finishing of plastic, composite materials and non-ferrous workpieces.
