S SATC 6" PSA Sanding Discs 100-Pack — 500 Grit Alumina, Self-Adhesive for Orbital Sander

S SATC 100-piece 6-inch PSA sanding discs are self-adhesive, 500-grit alumina abrasive discs made for fine sanding and polishing on orbital sanders.

These round PSA (pressure-sensitive adhesive) sanding discs from S SATC combine P-grade alumina abrasive with a heavy C-weight backing to resist clogging and deliver consistent fine finishes. The peel-off backing makes attachment fast and secure on any compatible 6" PSA backing pad, so you can get more done with less downtime. Supplied in a pack of 100, the discs are optimized for applications where a smooth, controlled cut and long life matter—auto body prep, woodworking, furniture finishing, fiberglass smoothing and light metal blending.

How do these 500-grit discs improve my sanding workflow?

500 grit sits in the fine range, offering gentle material removal while leaving a surface ready for polishing or topcoat. The anti-static, wear-resistant alumina reduces loading and extends usable life, which means fewer disc changes and more continuous sanding.

• Fine-cut 500 grit for smoothing and pre-polish work
• Anti-static coating reduces clogging on resinous woods and fillers
• P-grade alumina abrasive provides consistent cutting with controlled finish
• Heavy C-weight paper backing balances flexibility and durability

Will these discs stick to my orbital sander easily?

The discs use PSA backing with a peel-off protector so they attach quickly and remain secure under typical orbital sander operation. The adhesive is strong enough for aggressive passes yet allows removal without excessive residue when replacing discs.

• Peel-off protective liner for quick application
• Pressure-sensitive adhesive bonds to standard 6" PSA backing plates
• Designed for reliable hold during sanding cycles
• Removes cleanly to avoid gumming the pad between changes

What materials and projects are these discs best suited for?

S SATC 500-grit discs are versatile for a wide range of materials and finishing tasks. They excel at feather edging, smoothing body filler, preparing paint, and giving wood or metal a refined surface before polishing.

• Auto body and paint shop tasks: feather edging, paint prep
• Woodworking and furniture: fine sanding before staining or finishing
• Metalworking and fiberglass: light blending and surface finishing
• Household DIY: sanding plastics, rubber, drywall touch-ups

How many discs are included and what should I expect packaging-wise?

The pack contains 100 individual 6-inch discs in yellow backing, stacked for compact storage. Each disc has its own peel-off liner and is ready to use right out of the package, making it practical for professional shops and hobbyists alike.

• 100 discs per pack for extended use and reduced reordering frequency
• Yellow discs for easy visibility in busy shops
• Individually protected with peel-off liner to preserve adhesive
