Description
The Sia 1950 Siaspeed 6″ S-Performance Multi-Hole Sanding Discs in 400 grit (Part Number: 8443.7842.0400) are premium abrasives developed for high-efficiency surface preparation and fine sanding. Part of the trusted 1950 Siaspeed series, these discs offer a durable and flexible FSC-certified paper backing that adapts easily to contours and edges for consistent results across wood, metal, paint, and composite surfaces.
The 400 grit rating makes these discs ideal for intermediate sanding operations—perfect for smoothing repaired surfaces, preparing primer layers, or refining previous grit passes. They are coated with a stearate layer to resist loading and extend usable life, especially in dry sanding conditions.
An 81-hole pattern allows for superior dust extraction, maintaining a cleaner workspace and better visibility during sanding. Suitable for both wet and dry use, these discs are optimized for professional environments requiring speed, consistency, and cleanliness. Each box contains 100 discs.
