SiaSpeed 1950 5-Inch Sanding Discs: High-Performance 40 Grit PSA Power

Aggressive Stock Removal with SiaSpeed 1950 Adhesive Technology

The 1950 SiaSpeed 5″ Sanding Disc in 40 grit is a heavy-duty powerhouse designed for rapid material removal and stripping. Engineered for maximum efficiency on 125mm sanders, this extra-coarse abrasive features a high-performance Adhesive Back (PSA) for a low-profile, rock-solid bond to your backing pad. The SiaSpeed series is celebrated for its unique abrasive structure that delivers a high initial cut, making it the ideal solution for stripping old paint, removing rust, and leveling heavy body fillers or raw wood.

Industrial Grade Durability with PSA Precision

Crafted to thrive in high-production environments, the SiaSpeed 1950 series utilizes a specialized stearate coating that prevents loading and heat buildup. At the 40 grit level, this anti-clogging technology is essential for maintaining a sharp, aggressive cut through “sticky” substrates like fiberglass or resins. The Pressure Sensitive Adhesive (PSA) backing ensures the disc stays perfectly flat against the sander, providing superior edge stability and precision leveling that Hook & Loop systems can’t always match.
