Description
Overview
Mirka Q.Silver ACE 6" Grip Sanding Discs are a premium ceramic abrasive disc engineered for tough, universal sanding on hard substrates where conventional aluminum oxide loses cut too quickly. The ceramic grain self-sharpens under pressure, delivering sustained cutting speed and longer disc life on metals, hardwoods, composites, and solid surfaces. The semi-open coating with resin-on-resin bonding resists loading on softer materials, making Q.Silver ACE a versatile choice across automotive, woodworking, and fabrication applications.
Key Features
- Ceramic abrasive grain – self-sharpening crystals maintain cutting speed significantly longer than aluminum oxide on hard metals, dense hardwoods, and composites
- Semi-open coating – reduces loading on body filler, primer, and wood coatings while maintaining aggressive cut on harder substrates
- Resin-on-resin bonding – superior bond strength resists heat and pressure during high-speed random orbital sanding
- Paper backing – flexible and tear-resistant; conforms to slight surface variations without cracking
- Grip (hook-and-loop) attachment – fast disc changes on standard 6" hook-and-loop backup pads; compatible with most 6" random orbital and DA sanders
- 50 discs per box – production-ready quantity for body shops and fabrication operations

Application Suggestions
- Automotive body repair: Fine finishing passes on body filler, high-build primer, and bare metal panels; featheredging and surface prep before base coat
- Metal fabrication: Stock removal and surface prep on steel, stainless steel, cast iron, copper alloys, and non-ferrous metals
- Wood & cabinetry: Aggressive stock removal on hardwoods (oak, beech, birch, teak, mahogany) and engineered panels (MDF, chipboard, veneer)
- Solid surface & composites: Sanding DuPont™ Corian®, Samsung™ Staron®, LG HI-MACS®, and fiberglass composite panels
- Paint stripping: Removing old paint and coatings from metal and wood substrates
Compared to Alternatives
- vs. Mirka Gold 6" discs: Q.Silver ACE ceramic grain lasts significantly longer and cuts faster on hard metals and dense hardwoods; Mirka Gold aluminum oxide is the better value for mixed-substrate body shop use. Choose Q.Silver ACE for demanding metal and hardwood work; choose Gold for general-purpose finishing
- vs. Indasa RhynoGrip WhiteLine 6" (61 Series): Q.Silver ACE ceramic grain outperforms Indasa’s aluminum oxide on hard metals and dense composites; Indasa WhiteLine 61 Series is the better value for high-volume sanding of fillers, primers, and softwoods
- vs. 3M Cubitron II 6" discs: Both use ceramic grain technology; Mirka Q.Silver ACE offers comparable cutting performance with a semi-open coating for better anti-clog performance on mixed substrates
