01｜Product Overview
3M 7521C non-woven abrasive hand pad is a flexible surface conditioning consumable made of high-strength nylon fiber substrate compounded with premium aluminum oxide abrasive grains. It features thin and soft texture, excellent foldability, and can be rolled or twisted freely to reach grooves, gaps and irregular hidden areas. It delivers consistent grinding performance, effectively preventing over-cutting and protecting workpiece edges and corners. It supports both dry and wet grinding, with good water and oil resistance. The open three-dimensional mesh structure keeps grinding stable, and the abrasive grains shed synchronously with fiber wear to maintain stable finishing effect. It is an ideal hand abrasive for metal cleaning, rust removal, deburring and pre-painting treatment, widely used in metal processing, hardware, woodworking and equipment maintenance fields.
02｜Product Advantages
*It is thin, flexible and foldable, easy to twist and roll, adapts to complex contours and hidden gaps for all-around finishing.
