3M™ Hookit™ Microfinishing Film Disc 366L, 30 Mic 3MIL, Type D, 3 in x NH, D/F 3HL, Die 300BE, 100/Bag, 1000 ea/Case

The 3M Hookit Microfinishing Film Disc 366L is a high-quality abrasive disc designed for sanding and finishing applications. It features a load resistant coating that minimizes loading, increasing efficiency and product life. The abrasive is resin-bonded, providing flexibility without sacrificing durability and reliable performance under high heat and pressure. 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. The 3M Hookit attachment and removal system securely holds the disc during use and allows for easy disc change out. This disc is designed for use with orbital and random orbital sanders and comes in a range of grades for complete multi-step sanding and finishing.

The 3M Hookit Microfinishing Film Disc 366L features precision, micron-graded aluminum oxide, a popular choice among industrial professionals. Aluminum oxide is known for its fast cut-rate and long life. It is a tough and durable abrasive that self-fractures to expose fresh cutting edges, providing consistent performance over time. Unlike traditional natural abrasives, aluminum oxide dulls more slowly, making it ideal for grinding applications as well as sanding and finishing. It is suitable for use on a wide variety of materials in both woodworking and metalworking, including ferrous alloys.

Hook-and-loop products, such as 3M Hookit products, offer convenience and ease of use. The hook-and-loop backing allows for quick and secure attachment to a backup pad (sold separately). The tiny hooks on the backing firmly engage the loops on the backup pad, providing a reliable connection during use. This attachment and removal system is efficient and allows for easy switching between different abrasive products. The hook-and-loop system can be used again and again for the life of the abrasive, providing cost savings and convenience.

3M sanding discs come in various forms to fit different power tools and disc pads. Hook and Loop sanding discs are specifically designed for use with random orbital sanders. These handheld sanding machines rotate the disc in a random pattern to prevent swirl marks on the workpiece surface. The sanding disc is attached to a backup pad (sold separately) using the hook-and-loop system. Hook-and-loop discs are quick and easy to change when switching between different grades of abrasives. They can be reused multiple times until worn out, unlike adhesive-backed discs which are typically discarded after one use.
