Electroplated Diamond Dot Laps: Precision Grinding with Magnetic Ease

Elevate your grinding, faceting, and finishing work with Electroplated Diamond Dot Laps—a cutting-edge solution for precision tasks on hard materials like gemstones, glass, ceramics, and metals. Combining ultra-thin design, magnetic convenience, and electroplated diamond durability, these abrasives deliver unmatched control and consistency for professionals and hobbyists alike.

Key Features

  • Electroplated Diamond Dots: 100% diamond particles bonded to a spring steel sheet with nickel plating for long-lasting, rust-free performance.

  • Magnetic Backing: Rubberized magnetic layer ensures instant, secure attachment to metal grinder wheel heads—no adhesives required.

  • Ultra-Thin Design (1mm): Minimizes distortion and maintains flatness for precise, even grinding without uncontrolled scratching.

  • No Shedding: Diamonds are permanently bonded, eliminating loose grit, gouging, or bare spots during use.

  • Multi-Grit Versatility: Easily swap disks to transition between coarse grinding and fine polishing.

Why Choose Diamond Dot Abrasives?

  • Precision Control:
    Thin, flexible steel sheet conforms to flat or contoured surfaces.
    Produces sharp facets, smooth bevels, and scratch-free finishes.

  • Durability & Longevity:
    Electroplated diamonds resist wear, even under heavy use.
    Rust-proof construction ideal for wet or dry grinding.

  • Effortless Workflow:
    Magnetic backing allows instant grit changes—no downtime for adhesive cleanup.
    Lightweight design reduces vibration and improves handling.

  • Material Versatility:
    Works on glass, stone (agate, jade, quartz), ceramics, hardened metals, and composites.

Applications

Pro Tips for Optimal Use

  • Secure Mounting: Ensure the grinder’s metal wheel head is clean for maximum magnetic adhesion.

  • Light Pressure: Let the diamonds do the work—avoid forcing the disk to extend its lifespan.

  • Coolant Compatibility: Use water or lubricants to reduce heat buildup and enhance cutting efficiency.

  • Storage: Keep disks flat and dry to maintain their shape and magnetic integrity.

Technical Advantages Over Traditional Abrasives

  • No Adhesive Residue: Magnetic attachment eliminates glue cleanup between grit changes.

  • Consistent Surface Contact: Thin, rigid steel prevents uneven wear or "dishing" common in thicker disks.

  • Reduced Material Waste: Precise grinding minimizes over-removal of valuable substrates (e.g., gemstones).

Ideal For:

  • Lapidary Artists: Perfect for faceting machines or flat laps.

  • Glass & Jewelry Makers: Achieve polished edges without scratches.

  • Industrial Technicians: Precision grinding in toolrooms or ceramics production.

  • DIY Enthusiasts: User-friendly design for hobbyist projects.
