3M™ Hookit™ Microfinishing Film Disc 366L, 80 Mic, Type D, 11 in x NH, Die 1100F, 50/Carton, 100 ea/Case, PKG WI-04-101500

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, unlike traditional natural abrasives that dull more quickly. This makes it suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys. Its fast cut-rate, hardness, and strength make it widely used in grinding applications as well.

Hook-and-loop products, including 3M Hookit products, provide a convenient and efficient way to work with power tools. The hook-and-loop backing allows for quick and secure attachment to a backup pad, sold separately. The attachment is easy to use and provides a reliable hold during use. This system allows operators to focus more on the task at hand and less on tooling. The hook-and-loop attachment and removal system also allows for multiple uses, making it cost-effective and efficient for multi-step finishing processes.

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 and can be reused multiple times until worn out. In contrast, adhesive-backed discs are typically discarded after one use as the adhesive backing does not re-adhere a second time.
