Our 3x21 industrial grade silicon carbide belts are the perfect choice for fine finishing with lighter pressure. Silicon carbide is extremely sharp and friable, making it ideal for heat sensitive applications but not as long lasting as other abrasive materials. Its unique characteristics make silicon carbide a great choice for paint removal, sanding between coats, knife scale finishing, lapidary, or any application requiring consistent scratch patterns. Wet or dry applications. Hand built in the USA. Available Grits: 24, 36, 60, 80, 100, 120, 150, 180, 220, 320, 400, 600, 800, 1000  Single Gri

Heavy duty sanding belts for plastic, metal, wood, painted surfaces, and fiberglass

These premium sanding belts are designed for heavy-duty sanding and grinding of wood, metal, fiberglass and painted surfaces. The resin bonding system resists heat and humidity, extending the life of the sanding belt. The bi-directional flush joint runs smoothly in both directions without breaking.

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. Includes one 6 pack of the following grits: 60, 80, 100, 120, 150, & 180 The Belts are made from an Aluminum Oxide Cloth Industrial Grade material.
