Durable film construction provides the tear resistance needed for the use of coarse grades in high-production metalworking environments, particularly where edge wear is a concern.
3M Hookit Film Disc 375L is suitable for a variety of applications. When the goal is a superior wood finish, the 375L film disc in medium grades conforms well to the contours and rounded edges of challenging work surfaces to deliver a superior finish. Woodworking applications are further enhanced by a load-resistant coating and open coat construction, which reduce clogging and extend the life of the abrasive. For pre- and post-paint finishing, versatility is key, and the 375L film disc in fine grades is designed to deliver a superb uniform finish on plastics and clear coat technologies commonly used in the transportation industry.
3M Hookit Film Disc 375L is designed for use with a random orbital sander and the 3M Hookit backup pad (sold separately). It comes in a range of grades for various applications from rough sanding to very fine finishing.
Hook-and-loop style 3M Hookit discs are ideal for work spaces where adhesive backed discs may become contaminated by dust, dirt, or flying debris. They 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 and firmly attach to a hook-and-loop backup disc pad (sold separately) on a random orbital sander, can be removed cleanly and easily, and can be re-used again and again for the extent of the abrasive life. Hookit discs provide optimal performance when paired with a 3M Hookit disc pad.
Film-backed discs have excellent tear-resistant properties and provide a very uniform finish and consistent results with each use. This makes them an excellent option when working on paint, e-coats, primers, gel coats, glass, acrylics and solid surface material, wood topcoats and anywhere else a perfect finish is needed.
Aluminum oxide is a popular choice among industrial professionals because of its fast cut-rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges, whereas traditional natural abrasives dull more quickly. Due to its fast cut-rate, hardness, and strength, it is widely used in grinding applications in addition to sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys.
