PRODUCT FAQ

What is the 3M™ Microfinishing Film Belt 372L?

The 3M™ Microfinishing Film Belt 372L is a high-quality belt designed for use in micro-finishing applications. It features a precise abrasive coating that provides consistent cutting action and excellent surface finish.
What are the dimensions of this belt?

This particular version of the belt measures 2 inches by 72 inches and has a grit size of 15 microns. Each case contains fifty belts so you have plenty to work with.
Will these belts be compatible with my equipment?

This product should be compatible with most standard workshop sanding equipment. However, if you're not sure whether it'll fit your machine or not, just let us know what type of machine you have on hand, and we can double-check compatibility before placing an order.
Can I expect long life from these belts?

Yes! The film backing used in each one resists tearing while staying rigid enough to remain flat during grinding or polishing for longer periods than traditional cloth-backed abrasives would allow. Additionally, their consistent particle distribution results in fewer replacement requirements on our end-users' part compared to other similar products out there right now.

Flexible Design

3M™ Microfinishing Film Belt 372L is designed with a closed coat abrasive surface that enhances efficiency and produces a finer finish. The polyester film backing is flexible, allowing for a consistent finish over contours. It also offers greater tear-resistance than comparable paper products, making it ideal for high-production environments. This film is available in a range of micron grades for complete multi-step sanding and finishing.

Aluminum Oxide Abrasive

The 3M™ Microfinishing Film Belt 372L features precision, micron-graded aluminum oxide, which is a popular choice among industrial professionals due to its fast cut-rate and fine finish. This mineral is tough and durable, self-fracturing to expose fresh cutting edges. Its fast cut-rate, hardness, and strength make it widely used for sanding and finishing applications.

Heat Resistant with Closed Construction

The 372L belt uses a resin bonding that is specially designed to resist thermal and chemical deterioration that can occur during sanding. This bond is tough and excellent for precision work on hard and soft surfaces, allowing for faster sanding and a higher cut rate. The closed-coat construction of the belt means mineral grains cover 100% of the backing, so the abrasive scratches all of the surface that it comes in contact with. It's commonly used on surfaces where loading is less of a problem, making it a good match for hard metals.
