The 3M™ Stikit™ Film Disc 360L w/ Tab offers outstanding tear resistance, flexibility, and a consistent, uniform finish. Premium aluminum oxide abrasive grain provides a fast cut-rate and extended product life for greater productivity. Durable film construction provides the tear resistance needed for the use of coarse grades in high-production metalworking environments.

The film backing also generates a uniform and consistent finish. With 3M™ Stikit™ pressure sensitive adhesive backing, this disc is easy to attach to a any smoth surface  and are easy to remove, while the tab makes it easy to separate the disc from its liner.

These versatile 3M™ Stikit™ Film Discs 360L are suitable for a variety of applications and conform well to the contours and rounded edges of challenging work surfaces to deliver a superior finish. Applications are further enhanced by a load-resistant coating and open coat construction, which reduce clogging and extend the life of the abrasive. The 375L film discs in fine grades are designed to deliver a superb uniform finish. 

The 3M™ Stikit™ Film Disc 360L come in a range of grades for various applications from rough sanding to very fine finishing.

3M™ Stikit™ discs, with a pressure sensitive adhesive coating on the backside, are ready for you to use. Attaching them is as simple as pressing on a sticker. And because the adhesive is pressure sensitive, the disc can be peeled off of the disc pad just as easily, leaving a clean surface for your next disc. A convenient liner prevents the adhesive from becoming dirty and keeps the backing sticky until applied.

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 you need the perfect finish every time.

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.
