PRODUCT FAQ

  1. What is the 3M Hookit Microfinishing Film Disc 366L used for?

    The 3M Hookit Microfinishing Film Disc 366L is used for micro-precision finishing, polishing or contour sanding. It can be used on different surfaces including metal, composite and gelcoat.

  2. What are the dimensions of the disc?

    This hook-and-loop backed abrasive disc measures six inches in diameter with no hole pattern (NH).

  3. How fine is this disc’s abrasive grain size?

    The 100-micron grade provides a uniform finish during sanding while still preventing loading.

  4. How many discs come in a case and how are they packaged inside?

    One case contains up to five hundred discs plus fifty additional coatings all together sealed for protection as one piece comprising an order. Each individual pieces will then be supplied stacked together within separate plastic bags designed to prevent dust or debris contamination.

  5. : Can I use other types of backing pads with these disks?

    : Yes, but only when using specific Pad Holes Assignments that must align clearly the shapes between holes layout such like Item #09-0077 located at www.Fastenal.com website under manufacturer catalog SKU#7000116486

The 3M™ Hookit™ Microfinishing Film Disc 366L

The 3M™ Hookit™ Microfinishing Film Disc 366L is a high-quality abrasive product designed for use with orbital and random orbital sanders. It features precision, micron-graded aluminum oxide, 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. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys.

These discs feature a load resistant coating to increase efficiency and product life by minimizing loading. The abrasive is resin-bonded and supports disc flexibility without sacrificing durability and reliable performance under high heat and pressure. To complement the effective abrasive action, the polyester film backing flexes to help achieve a consistent finish over contours and offers greater tear-resistance than comparable paper products, making it ideal for high-production environments. And the 3M™ Hookit™ attachment and removal system holds the disc securely during use and provides easy disc change out.

Whether the job requires a random orbital or rotary sander, buffer, grinder, drill, finishing sander or other power tool, hook-and-loop products allow the operator to focus more on the task and less on tooling. Abrasive products with hook-and-loop backing, including 3M™ Hookit™ products, are manufactured with loop material that attaches to a backup pad, sold separately, where tiny hooks firmly engage the loops. Attachment is quick, easy, and secure during use. Sanding, finishing, and surface conditioning products with the hook-and-loop attachment and removal system provide an efficient way to work through multi-step finishing processes and can be used again and again for the life of the abrasive.

3M Sanding Discs

3M sanding discs come in a variety of forms to fit various power tools and disc pads. Hook and Loop sanding discs are designed to be used with a random orbital sander, a handheld sanding machine that rotates the disc in a random pattern to prevent swirl marks from forming on the surface of the workpiece. The sander is fitted with a backup pad (sold separately) to which the sanding disc is attached. Hook-and-loop discs are quick and easy to change when switching from one grade to another, and can be reused again and again until worn out; whereas adhesive-backed discs are typically discarded after one use because the adhesive backing will not re-adhere a second time.
