Siapower 1550 Siapan 6-Inch Sanding Discs: Maximum 40 Grit Cutting Power
Extreme Stock Removal for the Toughest Industrial Tasks
The Siapower 1550 Siapan 6″ Sanding Disc in 40 grit is the ultimate heavy-duty abrasive for rapid, aggressive material removal. Engineered for the initial stages of restoration and surface preparation, these discs excel at stripping stubborn coatings, heavy rust, and thick layers of floor varnish. The toughened, high-performance aluminum oxide grain provides a sharp, consistent cut that makes quick work of uneven timber and metal surfaces, allowing professionals to move through the toughest prep phases with minimal effort.
High-Performance 57-Hole Design for Maximum Debris Clearing
Coarse sanding at 40 grit creates significant debris that can quickly stall progress; however, the 57-hole vacuum pattern is specifically optimized to handle this high volume of waste. By maintaining constant airflow across the disc surface, the Siapower 1550 prevents dust buildup and “clogging” that typically shortens the life of lower-quality sandpaper. This advanced extraction technology ensures that each disc in the 50-piece box stays cool and sharp, providing unmatched durability for high-intensity orbital sanding applications.
