SiaPower 1550 5-Inch Sanding Discs: Superior 400 Grit Final Finishing

Perfect Your Surface with SiaPower 1550 Ultra-Fine Precision

The 1550 SiaPower 5″ Sanding Disc in 400 grit is engineered for professionals who require a flawless, ultra-smooth surface before the final polish or topcoat application. This fine-grade abrasive is ideal for delicate sanding between coats of paint, lacquer, or varnish, and for scuffing clear coats to ensure maximum adhesion. The 0-hole (solid) design provides a continuous, uninterrupted sanding face, which is essential for achieving a perfectly uniform scratch pattern and avoiding unwanted marks on sensitive workpieces.

Designed for durability and consistency, the SiaPower 1550 series utilizes advanced coating technology to prevent clogging and heat buildup, even during extended finishing sessions. Whether you are working on high-end automotive bodywork, cabinetry, or solid surface fabrication, these 125mm discs offer the flexibility and strength needed for precision work. The high-quality hook and loop backing ensures a secure fit on any 5-inch orbital sander, providing the stability required for master-class results.
