3M Wetordry Paper Disc 401Q, 12 in x NH, 1000 A-weight, 50 per inner 250 per case

3M™ Wetordry™ Paper Disc 401Q features extra-fast cutting silicon carbide on a lightweight paper backing to provide you with superior finishing for both wet and dry applications on a variety of substrates.

Use with Water for Dust ResistanceUsed with water, our 3M™ Wetordry™ Paper Disc 401Q enables the user to rinse areas of the workpiece and the disc during use to prevent dust and debris from clogging the points of the abrasive, while producing a faster cut at the same time. These versatile discs are ideal on surfaces that tend to generate a lot of dust, such as paint, primer and wood and can also be used dry for finishing metal and gel coats. Given that the disc can cut aggressively and keep loading to a minimum with the help of a lubricant, it's good for applications like paint prep, finish and repair as well as overall finishing, polishing and buffing.
Essential IngredientsWe chose silicon carbide, a mineral that 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 paint prep and finishing on wood and metal. While it wears faster than aluminum oxide, it produces a superior finish. The light A-weight backing provides conformability over contours and into crevasses and corners.
3M™ Science Applied to Wetordry™ Abrasives3M™ Wetordry™ products are backed with a durable waterproof paper backing that supports both wet and dry applications. Lighter weight than cloth, and smooth rather than textured, paper backing is preferable for lighter applications such as finishing and paint prep. At the same time, many such applications produce a significant amount of dust, clogging the abrasive points and creating an inferior work environment. These effects can be minimized by sanding with water to rinse dust away from the workpiece and the abrasive surface.
