BOSHCRAFT 3x18 Inch Belt Sander Belts – 21-Pack Aluminum Oxide Belts (40/60/80/120/180/240/400 Grits)

Upgrade your sanding workflow with BOSHCRAFT 3x18 inch belt sander belts. This 21‑pack brings a complete spectrum of grits—40, 60, 80, 120, 180, 240, and 400—crafted from durable aluminum oxide. Designed for smooth material removal and even finishing, the belts perform across a variety of materials, including wood, metal, leather, aluminum, fiberglass, rubber, and plastic. The closed coat grain promotes a uniform cut, while the high‑adhesion backing helps keep the belt securely in place during longer sessions.

These belts are built to fit compatible belt sanders and offer a flat belt interface that minimizes bumping and chatter. A reinforced backing resists heat and moisture, preserving belt integrity when tackling stubborn surfaces. The anti‑static and anti‑clogging properties reduce dust buildup, helping you work longer between belt changes and maintain a cleaner workspace.
