Available in a variety of sizes, including 6 inch copper lap, copper flat laps, and 8 copper flat laps, our products are perfect for pre-polishing or final polishing.Our copper laps feature a 1mm and 3mm rolled copper face that is laminated to a 6mm thick aluminum master lap, ensuring a true turning surface. These traditional laps are designed to be charged with diamond powder and are compatible with most types of polishing compounds.Compared to zinc polishing lap, tin polishing lap, and chrome oxide polishing lap, our copper flat laps offer superior grinding performance and durability. Additionally, our copper flat laps with master lap can be re-machined if it becomes damaged, contaminated, or worn with use.Whether you're a professional lapidary or an amateur enthusiast, our copper flat laps are the perfect choice for achieving a high-quality finish on even the most delicate and brittle materials.

Key Characteristics:

  1. Copper Base: The copper flat laps typically consists of a flat, circular, or square copper base that provides stability and durability to the tool.

  2. Diamond or Other Abrasive Coating: The working surface of the copper flat laps is coated with diamond grit or other abrasive materials. Diamond is often used due to its hardness and durability, making it effective for grinding and polishing gemstones and minerals.

  3. Various Grit Sizes: copper flat laps are available with different grit sizes, ranging from coarse to fine. Coarser grits are used for shaping and polishing , while finer grits are employed for polishing and finishing.


  1. Gemstone Cutting: Lapidarists use copper flat laps to shape and facet gemstones. The abrasive surface of the flat lap helps create precise facets and angles on gemstones, enhancing their brilliance and sparkle.

  2. Cabochon Making: Cabochons are polished, domed gemstone shapes with a flat base. Copper flat laps are used to shape and polish cabochons to achieve a smooth, glossy finish.

  3. Mineral and Rock Polishing: Geologists and collectors use copper flat laps to polish mineral specimens and rocks. This process can reveal the natural beauty and patterns within the specimens.

  4. Lapidary Art: Artists and craftsmen use copper flat laps for various lapidary art projects, such as creating custom jewelry pieces with polished gemstones.

  5. Fossil Preparation: Paleontologists and fossil enthusiasts use flat laps to carefully remove rock and matrix from fossils while preserving the delicate fossil material.

  6. Glass and Ceramics: In addition to lapidary work, copper flat laps can also be used for shaping and polishing glass and ceramics.

  7. Metalworking: Some metalworkers use copper flat laps with abrasive coatings for finishing and polishing metal surfaces.

Copper flat laps are versatile tools in the lapidary and mineralogical fields, providing precise control over shaping and polishing processes. They are available in various sizes and configurations to accommodate different lapidary tasks and are essential for achieving professional-quality results in gemstone cutting and lapidary artistry.

How do you electroplate diamond tools?

In the diamond electroplating process, the tool body (negatively charged) is placed in a tank where the diamond grit (positive charge) is “tacked” to the exposed surface. Nickel is then electroplated to strengthen the hold of the diamond grit to the body.

How are diamond coated tools made?

Plated diamond tools: These tools are made by fixing the diamonds onto the tool's base via electroplating method or via CVD (Chemical Vapor Deposition) method. They can usually be made to good processing precision. Ceramic-bonded diamond tools: The tools' bonding material is usually glass and ceramic powder.

What are the benefits of diamond tools?

Tools that use diamonds have higher wear resistance, higher grinding efficiency, and a longer lifespan. Diamond saws and drills will help ensure a high-quality cut for concrete projects, and will reduce time and effort. Synthetic diamonds are a regular fixture in the construction industry.

What are electroplated diamond tools?

Electroplated diamond tools have a monolayer of abrasive coating on a metal substrate. The individual diamond grits are bonded through an electroplated nickel layer. They project well out of the bond so that very open, easy cutting tools with exceptionally large chip spaces are created.

What kinds of processes require the use of diamond tools?

1. Geological Exploration and Mining. Diamond cutting tools are used in the oil/gas industry for drilling and mining bits. ... 2. Construction. ... 3. Stone Processing Applications. ... 4. IT and Home Appliances. ... 5. Engineering Ceramics Applications.
