SiaSpeed 1950 6-Inch Sanding Discs: High-Performance 400 Grit Final Finish
Achieve a Master-Class Surface with SiaSpeed 1950 Precision
The 1950 SiaSpeed 6-inch Sanding Disc in 400 grit is the definitive choice for professionals seeking an ultra-smooth, paint-ready surface on large workpieces. Optimized for 150mm orbital sanders, this extra-fine abrasive is specifically engineered for the final preparation stages, such as sanding between coats of lacquer, scuffing clear coats, and refining high-quality primers. The SiaSpeed technology provides a high initial cutting power for such a fine grit, ensuring your sander produces a perfectly uniform texture across delicate automotive, marine, and woodworking projects in record time.
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 is especially critical at the 400 grit level to prevent “pilling” or burning the topcoat. The 0-hole (solid) design provides a continuous abrasive face, ensuring 100% contact and a flawless scratch pattern. The premium Hook & Loop backing offers a secure, centered attachment for vibration-free sanding, while the 100-pack box ensures you have the volume needed to maintain a high-speed professional workflow.
