Siapower 1550 Siapan 6-Inch Sanding Discs: 150 Grit Multi-Purpose Finishing

Achieve Consistent Surface Quality with 150 Grit Precision

The Siapower 1550 Siapan 6″ Sanding Disc in 150 grit is designed for professionals who need a versatile abrasive that bridges the gap between material removal and final finishing. This medium-fine grit is exceptionally effective at smoothing out coarser sanding marks on wood, metal, and automotive fillers. Utilizing premium aluminum oxide grains, these discs provide a fast and uniform cut, ensuring your surfaces are perfectly leveled and prepared for the next stage of priming or staining.

Reliable 15-Hole Vacuum System for Enhanced Productivity

Engineered with a strategic 15-hole pattern, these discs offer excellent dust extraction and airflow management. By pulling sanding debris through the vacuum holes, the disc maintains a sharp cutting edge and prevents the accumulation of heat that can damage delicate surfaces. This 15-hole configuration is compatible with a wide variety of standard orbital sanders, making it a reliable choice for shops that require a clean environment and long-lasting disc performance from their 50-piece box.
