The 3M Hookit Microfinishing Film sheet 366L is designed to help you get a range of finishes and can be easily cut to fit a variety of different tools. It features micron-graded aluminum oxide abrasive bonded to a durable polyester film backing to produce a fast cut-rate and uniform finish on wood, composites, plastic, fiberglass and metal.Flexible Design
The 3M Hookit Microfinishing Film Sheet 366L is manufactured with an open coat surface to increase efficiency and product life by minimizing loading. The abrasive is resin-bonded and supports disc flexibility without sacrificing durability and reliable performance. 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.
The Convenience of 3M Hookit
The Hookit hook-and-loop feature makes sheet attachment, removal, and re-attachment clean and easy, and facilitates use and re-use of the sheet for the full extent of its abrasive life. Hookit sheets have J-shaped hooks of the type most commonly used in everyday hook-and-loop applications. Hookit sheets grip the brushed nylon loop backings of 3M Hookit disc pads, file shoes and blocks. It’s simple: just set the sheet in place and start sanding. The sheet removes just as cleanly and easily. The Hookit system is designed for work spaces and applications where adhesive backed sheets may become contaminated by dust, dirt, or flying debris.
Aluminum Oxide Abrasive
The 3M Hookit Microfinishing Film Sheet 366L features precision, micron-graded aluminum oxide, which is a popular choice among industrial professionals because of its fast cut-rate and fine finish. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges. Due to its fast cut-rate, hardness, and strength, it is widely used for sanding and finishing applications.
