Starcke Blue Zirconium Sanding Discs – German-Made, High-Performance Abrasive
Starcke Blue Zirconium has consistently been our top-selling mineral from the Starcke abrasive line — and for good reason. While other brands have released low-quality zirconium products that hurt the mineral’s reputation, Starcke continues to prove how strong this abrasive truly is. Many contractors directly compare these discs to Norton Red Heat ceramic aluminum oxide, often saying Starcke Blue goes longer at a fraction of the cost.
These discs use premium zirconium grains that are carefully selected and evenly coated using advanced German manufacturing technology. The backing is a tightly woven, thick yet flexible material that resists tearing, runs cooler, and improves heat dissipation — making it ideal for aggressive stock removal and extended sanding life.
Perfect for hardwood flooring professionals who demand durability, speed, and consistency.
