8 in Silicon Carbide Lapping Film Discs, 10-Pack, PSA-Backed for Glass, Stone & Metal

The 8 in Silicon Carbide Lapping Film Discs (10-Pack, PSA-Backed) combine sharp, fast-cutting silicon carbide mineral grains with a pressure-sensitive adhesive backing for rapid, high-precision stock removal and surface leveling.

Key Features

• Sharp Silicon Carbide Mineral: Fast-fracturing synthetic SiC crystals expose fresh, razor-sharp cutting edges continuously under pressure, delivering rapid stock removal on brittle lapidary and metallurgical materials.
• Pressure-Sensitive Adhesive (PSA) Backing: Peel-and-stick adhesive attaches firmly to 8-inch flat lap platen discs or master plates without slipping, wrinkling, or bubbling.
• Durable 3 mil Polyester Film: Tear-resistant Mylar base ensures consistent flatness across the entire 8-inch working face during wet and dry lapping.
• Convenient 10-Piece Pack: Economical multi-disc supply designed for high-efficiency production workshops and precision lapidary studios.

Recommended Applications

• Pre-polishing and fine grinding of lapidary gemstones (agate, jasper, quartz, jade, and petrified wood).
• Glass edging, optical component beveling, and bevel flattening.
• Metallographic sample grinding, cross-section specimen preparation, and micro-hardness testing mounts.
• Ceramic, carbide, and non-ferrous metal precision surface refinement.

Operating Guidelines

• Clean master lap platen thoroughly with isopropyl alcohol before applying the PSA disc.
• Operate wet with a steady water drip or coolant to prevent thermal build-up and extend film life.
• Use moderate, flat contact pressure to maintain uniform disc wear.
