3M™ Hookit™ Wetordry™ Paper Disc 401Q, 2000 A-weight, 3 in x NH, Die 300V, 100/Pac, 500 ea/Case

3M™ Hookit™ Wetordry™ Paper Disc 401Q is a versatile abrasive disc that can be used with water to prevent dust and debris from clogging the abrasive points, while producing a faster cut. It is ideal for surfaces that generate a lot of dust, such as paint, primer, and wood, and can also be used dry for finishing metal and gel coats.

The disc is made with silicon carbide mineral, which 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. Although it wears faster than aluminum oxide, it produces a superior finish.

3M™ Wetordry™ products are backed with a proprietary durable waterproof paper backing that supports both wet and dry applications. The paper backing is lighter weight than cloth and smooth rather than textured, making it preferable for lighter applications such as finishing and paint prep. However, sanding with paper backing can produce a significant amount of dust, clogging the abrasive points and creating an inferior work environment. This can be minimized by sanding with water to rinse dust away from the workpiece and the abrasive surface.

3M offers a complete line of hook-and-loop style 3M™ Hookit™ discs for workspaces where adhesive-backed discs may become contaminated by dust or dirt. Hookit™ discs are often used in applications where a 3M™ Stikit™ disc may be too aggressive, as Hookit™ discs tend to leave finer finishes than adhesive-backed discs. Hookit™ sanding discs conveniently attach to a hook-and-loop backup disc pad (sold separately), can be removed cleanly and easily, and can be re-used again and again for the extent of the abrasive life.
