3M™ Hookit™ Gold Film Disc 255L features aluminum oxide abrasive grain on a film backing for a fast cut-rate and uniform, close-tolerance finish on wood, paint prep, and defect repair applications. The flexible film backing provides a consistent finish and greater tear-resistance than a comparable paper product, making it well-suited for a high-production environment.
- Aluminum oxide abrasive offers a fast cut, long life, and professional performance on many surfaces
- Tear-resistant film backing provides a close-tolerance, consistent finish
- 3M™ Hookit™ discs are easy to change and reuse, maximizing utility for the life of the disc
- Open coat construction provides a more aggressive cut
- Load-resistant coating prevents dust and debris from clogging the disc

What is the size of each 3M™ Hookit™ Gold Film Disc 255L?
Each disc measures 3 inches in diameter and has a no hole (NH) design, which means it can be used with any dust extraction or vacuum system.
How many discs come in a pack and how are they packaged?
Each carton contains 50 discs, while each case includes four cartons for a total of 200 pieces. The discs are individually lined up on tear-off pads to ensure easy dispensing and to prevent damage during transportation.
What grit level does the P240 rating correspond to on the sandpaper scale?
The P240 rating indicates that these Hookit Gold Film Discs offer fine sanding abrasion suitable for creating smooth surface finishes between coats without generating excessive heat. This corresponds to approximately #320-#400 range on conventional paper-based abrasive scales depending upon manufacturer variance.
The 3M™ Hookit™ hook-and-loop attachment is a reliable and efficient solution for sanding and finishing applications. It allows for easy re-use when switching between grades before the discs are worn out. The open coat feature provides a more aggressive cut than a comparable closed coat abrasive of the same grade, and the disc's load-resistant coating reduces clogging of the disc, making this a good choice for woodworking and other applications where loading hinders performance. Designed for use with a random orbital sander, this disc comes in a range of grades for fine sanding and finishing, and is resin-bonded for reliable performance under high heat and pressure.Aluminum Oxide Abrasive
These discs feature an aluminum oxide abrasive, which 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.Open Coat Construction
Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys. Coated abrasive discs cut better and last longer when dust isn't clogging the cutting surface of the abrasives. Open coat construction means the abrasive grains are placed with space between them to help evacuate sanding dust and other debris to avoid clogging the cutting edge of the grains. The load-resistant coating also allows the disc to continue cutting even when sanding softwoods, paints, and other materials that would, otherwise, clog the disc and hinder sanding ability. Additionally, the open coat feature provides a more aggressive cut than a comparable closed coat abrasive of the same grade. All of this adds up to increased productivity and reduced material consumption.Hookit™ Sanding Discs
3M also offers a complete line of hook-and-loop style Hookit discs 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.
