SiaSpeed 1950 5-Inch Sanding Discs: High-Performance 400 Grit Final Finish

Achieve a Master-Class Surface with SiaSpeed 1950 Precision

The 1950 SiaSpeed 5″ Sanding Disc in 400 grit is the definitive choice for professionals seeking an ultra-smooth, paint-ready surface. This extra-fine abrasive is specifically engineered for final preparation stages, such as sanding between coats of lacquer, scuffing clear coats, and refining high-quality primers on 125mm sanders. The SiaSpeed technology provides a high initial cutting power that stays consistent, ensuring your orbital sander produces a perfectly uniform texture across delicate automotive, marine, and woodworking projects.

Industrial Grade Durability with Advanced Anti-Clogging

Crafted for high-production environments, the SiaSpeed 1950 series features an innovative stearate coating that prevents dust loading and heat friction. This ensures that the 400 grit grains remain exposed and sharp, providing a consistent finish without the risk of “pilling” or burning the topcoat.
