3M Hookit Film Disc 371L, P120 3MIL, 5 in x NH, Die 500X, 50/Carton, 250ea/Case

• 3M Hookit disc is easy to change and reuse, maximizing utility for the life of the disc
• Closed coat provides greater grain density and finer finish on hard surfaces
• Durable film backing is tear-resistant and provides a uniform, consistent finish
• Manufactured without an anti-loading coating for substrates that are sensitive to contamination
• Premium aluminum oxide abrasive offers a fast cut and long life on many surfaces

3M Hookit Film Disc 371L delivers outstanding tear resistance, flexibility and a consistent, uniform finish on a variety of substrates. Premium aluminum oxide abrasive grain offers a fast cut-rate and extended product life for greater productivity.

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.

3M Hookit Film Disc

The 3M Hookit Film Disc 371L is designed for easy changing and reusing, maximizing the disc's utility throughout its life. This model features a durable film backing that resists tearing and ensures a consistent finish every time.

Its hook-and-loop system makes it ideal for workspaces where adhesive discs might get contaminated. The 371L model offers a reliable sanding experience with a uniform finish on various surfaces.

Premium Aluminum Oxide Abrasive

This disc uses premium aluminum oxide abrasive, known for its fast cut rate and long life. The abrasive self-fractures to expose fresh cutting edges, maintaining performance over time.

Aluminum oxide is suitable for many materials, including ferrous alloys, making the 371L a versatile choice for both woodworking and metalworking tasks.

Size And Format Details

The disc measures 5 inches in diameter and features a NH (non-hole) format, fitting a variety of sanding tools. This size is common for random orbital sanders, providing good control and coverage.

Its 3MIL thickness balances durability and flexibility, allowing it to conform to surfaces while resisting damage during use.

Grade And Backing Features

This product comes in a P120 grade, suitable for medium sanding tasks. The closed coat abrasive ensures greater grain density, delivering a finer finish on hard surfaces.

The film backing is tear-resistant and uniform, supporting consistent results. It’s manufactured without an anti-loading coating, ideal for substrates sensitive to contamination.

Pack Count And Usage

The 3M Hookit Film Disc 371L is sold in cartons of 50 discs, with 250 discs per case. This pack size supports high-production environments and frequent sanding needs.

Designed for use with a random orbital sander and compatible 3M Hookit backup pads (sold separately), it suits a range of applications from rough sanding to fine finishing.
