4" x 36" Metal Grinding Zirconia Sanding Belts - 3 PK (4436024Z-3)
Industrial Strength for High-Pressure Grinding
The POWERTEC 4436024Z-3 is a high-performance 3-pack of 4 x 36-inch zirconia sanding belts, specifically engineered for the most aggressive material removal tasks in metalworking and heavy-duty woodworking. Featuring an extra-coarse 24-grit Zirconia Alumina grain, these belts are designed for "brute force" applications like weld grinding, stainless steel deburring, and stripping multiple layers of industrial coatings. The self-sharpening nature of Zirconia means the grain fractures during use to reveal new, sharp cutting edges, ensuring consistent performance throughout the belt's life.
Built on an ultra-strong Y-weight cloth backing, these belts provide the high-tensile strength and dimensional stability required for high-torque stationary belt sanders. The high-performance resin-on-resin bond ensures maximum grain retention and superior heat resistance, preventing "glazing" and protecting the workpiece from friction burns. Whether you are leveling heavy metal stock or dimensioning the hardest of wood stock, this 3-piece set delivers the industrial durability required for professional fabrication.
- Aggressive 24 Grit: Maximum material removal rate for heavy grinding and initial-stage surfacing.
- Zirconia Alumina Grain: Self-sharpening abrasive lasts significantly longer than standard aluminum oxide.
- Cool-Cutting Tech: Designed to dissipate heat quickly, reducing the risk of bluing steel or burning wood.
- Industrial Y-Weight Backing: Heavyweight polyester/cotton blend resists tearing under extreme pressure.
- Multi-Material Muscle: Superior performance on stainless steel, tool steel, cast iron, carbides, and dense hardwoods.
