  1. What is the size of 3M™ Hookit™ Film Disc 371L?

    The diameter of the disc is 5 inches with no hole pattern (NH).

  2. What does P180 mean on this product?

    It represents the grade/coarseness level. P180 grit implies that it has a medium grain and suitable for paint sanding.

  3. How many discs are there in one inner package of this product?

    There are 50 pieces per inner-pack.

  4. Can I use water while sanding with these film discs?

    Yes, you can because they have an excellent resistance to dust, loading and wear out due to moist condition during usage.

  5. . Will buying them by case save me money compared to just buying singles or packs

    . Absolutely! Buying it by case means you get a discounted bulk price. Each case contains about 250 units meaning you will save more than if you were purchasing them separately or in smaller packs as well as reduce risk running out regularly leading to loss production time

Versatile Efficiency

Durable, heavy duty 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 371L is suitable for a variety of applications. For pre-paint finishing, versatility is key, and the 371L film disc in fine grades is designed to deliver a uniform finish on plastics and aluminum commonly used in the transportation industry.

3M™ Hookit™ Film Disc 371L 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.

The Hookit™ Advantage

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 e-coats, primers, gel coats, acrylics and solid surface material, and anywhere else a perfect finish is needed.

Aluminum Oxide Abrasive

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.
