Sia Abrasives | 7940 Siaair 3" Velvet Foam Disc - Hook & Loop (10/BOX)

Minimum order: Sia Abrasives products require a $100 minimum order. Mix & match any Sia items to reach $100.

The 7940 Siaair 3" velvet foam disc is built from three layers: a net-backed abrasive on the outside, foam cushioning in the middle that equalizes pressure to prevent over-sanding, and the proven siafast hook and loop grip on the inside. It conforms to contours, curves, and edges for a flawless finish in both wet and dry sanding.
