Maximum Power Stripping: SiaSpeed 1950 6-Inch PSA Sanding Discs

High-Performance Material Removal with Ceramic Technology

When a project demands raw power and rapid results, the SiaSpeed 1950 6-inch 40-grit sanding disc is the ultimate heavy-duty solution.

Designed for professionals in the automotive, marine, and industrial metalworking sectors, this 40-grit powerhouse delivers unmatched material removal rates and incredible longevity.

The PSA (Pressure Sensitive Adhesive) backing ensures a rock-solid, flat attachment to your sanding pad, eliminating the “bounce” sometimes found with thicker systems.
