Description
The Sia 1950 Siaspeed 6″ S-Performance Multi-Hole Sanding Discs in 220 grit (Part Number: 8443.7842.0220) are precision-engineered abrasives designed to deliver consistent intermediate sanding results across a wide range of substrates. As part of the trusted Siaspeed 1950 series, these discs are built on a flexible FSC-certified paper backing that conforms easily to curved and flat surfaces, making them highly adaptable for both hand-held and machine sanding tasks.
The 220 grit rating is ideal for refining filler, leveling primer coats, and preparing surfaces for finer sanding or painting. Manufactured with white aluminum oxide and treated with a stearate coating, the discs offer excellent cutting power while minimizing clogging and heat buildup. This leads to smoother results and extended disc life, especially during dry sanding.
The optimized 81-hole dust extraction pattern maximizes airflow and helps maintain a cleaner work surface, reducing operator fatigue and improving finish quality. Packaged in boxes of 100, these discs are well-suited for high-volume use in automotive refinishing, woodworking shops, and general industrial applications.
