3M™ Hookit™ Microfinishing Film Sheet 366L, 40 Mic 3MIL, Type D, 2-3/4 in x 5 in

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.
