18" Magnetic Felt Polishing Pad for Glass & Stone

The 18" Magnetic Felt Polishing Pad is an oversized commercial wool polishing disc engineered for 18-inch flat lap machines, delivering comprehensive surface coverage and distortion-free, mirror-gloss finishing on large architectural glass, massive mineral slabs, and metal castings.

Key Features

• Full-Surface Magnetic Quick Mount: Mounts firmly and instantly onto 18-inch steel master laps with zero spray adhesive or tape, ensuring true concentric balance and effortless cleaning.
• Compressed Pure Wool Felt: Dense, uniform natural wool fibers retain cerium oxide, diamond compound, and aluminum oxide slurry evenly across the wide surface area.
• Substantial 18-Inch Diameter: Maximizes productivity and surface flatness across large crystal specimens, glass tabletop inserts, and oversized lapidary slabs.
• Vibration & Heat Buffering: Cushions working load and quickly dissipates frictional thermal buildup, safeguarding delicate minerals from stress cracking.

Recommended Applications

• High-gloss mirror polishing and haze removal on large glass artworks, architectural panels, and optical flats with cerium oxide.
• Flat lapping and pre-polish to final polish on large agate slabs, petrified wood, jasper, and quartz with diamond paste.
• Luster finishing and mirror buffing on large bronze, brass, and custom jewelry alloys.

Operating Guidelines

• Ensure steel master lap face is clean and completely free of loose grit before placing magnetic pad.
• Keep the pad uniformly damp with water or slurry throughout the polishing cycle; do not run dry.
• Rinse clean after use and store flat in a sealed container to preserve magnetic backing and prevent contamination.
