SiaPower 1550 5-Inch Sanding Discs: High-Performance 80-Grit Surface Preparation

Accelerate Your Workflow with SiaPower 1550 Technology

For professionals who need a balance of raw power and precision, the SiaPower 1550 5-inch 80-grit sanding disc is the definitive tool for medium-coarse surface preparation. This abrasive is expertly engineered to bridge the gap between aggressive stock removal and refined finishing. Whether you are leveling body patches, stripping stubborn old finishes from timber, or removing surface rust from metal, the 1550 series delivers a clean, predictable result every time.

The 0-hole (solid) configuration is a key performance feature, ensuring 100% surface contact between the abrasive and the workpiece. By eliminating dust holes, the disc provides maximum cutting efficiency across its entire 125mm face, resulting in a faster, more uniform finish on any standard orbital sander.

Industrial-Strength Durability for Tough Environments

The SiaPower 1550 series is built to endure the high-friction environments of industrial workshops. Unlike standard abrasives that fray or lose grit prematurely, these discs feature a reinforced backing that offers exceptional edge stability and high tear resistance. This means you can sand into corners and over contours without worrying about the disc falling apart.
