These belts are manufactured from the same "industrial" material as our other belts. To increase our manufacturing efficiency, we can use the smaller "leftover" pieces to make these standard size belts for your portable belt sanders. This helps us use up material and helps you because we can make these out of our best material very inexpensively.
There are 5 belts per grit pack.
The Belts are made from an Aluminum Oxide Cloth Industrial Grade material.
