SiaSpeed 1950 5-Inch Sanding Discs: High-Performance 150 Grit Intermediate Finishing

Achieve Superior Surface Uniformity with SiaSpeed 1950 Technology

The 1950 SiaSpeed 5″ Sanding Disc in 150 grit is a versatile, high-speed abrasive engineered for professional-grade surface refining. This grit is specifically designed to eliminate scratches left by coarser abrasives, providing a smooth, uniform surface ready for sealing or priming. The SiaSpeed line is celebrated for its ability to maintain a high cutting rate from the first pass, significantly reducing the time required for intermediate sanding on wood, metal, and automotive coatings.

Industrial Grade Durability for High-Volume Shop Performance

Designed to withstand the heat and friction of high-production environments, the SiaSpeed 1950 series utilizes a specialized stearate coating that resists clogging and pilling. This technology ensures that the 150 grit abrasive stays sharp and effective, even when working on “sticky” materials like fresh primers or softwoods. The high-quality Hook & Loop backing ensures a secure, vibration-free fit on your 5-inch sander, while the 100-pack box provides a reliable, long-lasting supply for any professional workshop.
