Sintered Faceting Laps


Precision cutting of facets on delicate materials requires top-of-the-line tools, and our Sintered Faceting Laps fit the bill perfectly. Tailored for use on glass, ceramics, crystals, and ultra-hard materials, these laps are indispensable in the polishing and grinding industry. With diamond matrix depths ranging from 3.5mm to 5mm and precision-ground steel cores, our sintered laps offer unparalleled durability and reliability, guaranteeing precise and flawless facet cutting for professionals.

When it comes to cutting facets on delicate and brittle materials like glass, ceramics, and crystals, or ultra-hard materials, you need a sintered diamond flat lap. Our Sintered Faceting Laps are designed to meet the demands of the polishing and grinding industry for these materials. With a diamond matrix depth of 3.5mm or 5mm, and precision-ground steel cores, our sintered laps are the most durable and long-lasting on the market.

Compared to Inland and Crystalite sintered laps, our laps have a deeper diamond matrix, which exposes new cutting points as the wheels are used. This means that our laps cut just as aggressively on the first facet as the last, and can be dressed to expose additional crystals for a more aggressive cut. However, dressing is not always necessary if you follow a "side to side" pattern when grinding to ensure even wear.

Our Sintered Diamond Laps come in a range of sizes, from 4" to 12", with diamond matrix widths of 40mm, 50mm, 60mm, 90mm, and 100mm. Dynamic balancing at the factory ensures concentricity for smooth and quiet grinding .

If you need to cut more facets than you can count, choose our Sintered Diamond Laps for the highest quality and most durable performance in the industry. Our 600 grit sintered laps and other sintered laps are the perfect choice for professionals and hobbyists alike.Diamond Mesh: 60 80 100 180 220 360 600 Grit

Q: What are sintered laps for faceting?
If you've been using plated laps, then upgrade your faceting game with sintered laps. These are a copper and diamond matrix on an aluminum. The laps are light weight but with a long lasting lifespan. The laps have approximately 5mm (1/5") of diamond sintered copper.
Q: What is a sintered diamond faceting lap?
A sintered diamond faceting lap is a lapidary tool made by sintering diamond abrasive particles onto a metal substrate. This process creates a durable and long-lasting abrasive surface suitable for polishing gemstone facets.
Q: What are the advantages of using sintered diamond faceting laps?
High cutting efficiency: Sintered diamond laps offer excellent cutting performance, allowing for efficient shaping and polishing of gemstone facets. Longevity: The sintered diamond abrasive surface is highly durable and resistant to wear, providing long-lasting performance. Consistency: Sintered diamond laps can produce consistent facet shapes and finishes, resulting in high-quality gemstone faceting. Versatility: They can be used for faceting a wide range of gemstone materials, including hard and abrasive stones.
Q: How to dress a sintered lap?
My favorite clean-up for my sintered laps is using barkeeper's friend and a scotch pad. It removed the build up rather well. When completed they run smooth and cut well. I usually scrub until the entire surface looks brassy new.
Q: How does a sintered diamond faceting lap work?
The abrasive diamond particles on the surface of the lap abrade the gemstone material, gradually shaping and polishing each facet to the desired angle and finish. Water or oil is often used as a lubricant and coolant during the faceting process to enhance performance and prevent overheating.
Q: What types of gemstones can be faceted using sintered diamond laps?
Sintered diamond faceting laps are suitable for faceting various gemstone materials, including quartz, sapphire, ruby, spinel, garnet, tourmaline, and many others. They are particularly well-suited for faceting harder gemstones that may be challenging to work with using other lapidary tools.
