Siapower 1550 Siapan 6-Inch Sanding Discs: Heavy-Duty 40 Grit Stripping

Aggressive Material Removal for the Toughest Restoration Tasks

The Siapower 1550 Siapan 6″ Sanding Disc in 40 grit is a high-performance abrasive designed for extreme material removal and rapid surface leveling. This extra-coarse grit is the professional’s choice for the initial stages of restoration, such as stripping thick layers of old paint, removing heavy rust from metal, or flattening rough-sawn timber. Built with toughened aluminum oxide grains, these discs maintain their aggressive cutting power under high pressure, allowing you to move through heavy-duty prep work with speed and precision.

Reliable 15-Hole Dust Extraction for Clog-Free Performance

Sanding at a 40-grit level creates significant debris; however, the integrated 15-hole vacuum pattern ensures your workflow remains efficient. This strategic hole configuration facilitates consistent airflow, pulling large dust particles away from the disc surface instantly to prevent “loading” and heat friction. By keeping the interface clean, the Siapower 1550 extends the utility of every disc in this 50-piece box, ensuring long-lasting performance even when tackling the most demanding industrial surfaces.
