6" Sintered Diamond Faceting Laps – 60 to 600 Grit, 5mm Thick Diamond Matrix

The Sintered Diamond Faceting Lap is a professional-grade lapidary tool designed for gemstone faceting, precision shaping, and heavy grinding of hard materials such as sapphire, ruby, quartz, and other crystals. Unlike standard electroplated diamond laps that feature only a thin diamond coating, this lap is built with a 5mm thicksintered diamond matrix that continuously exposes fresh diamond particles as it wears, ensuring consistent, aggressive cutting power and unmatched durability. With a total thickness of 15–20mm and a 50mm sintered width, it delivers long-lasting performance that outlives plated or brazed alternatives many times over, making it a cost-effective investment for serious lapidary artists despite its higher upfront cost. Available in grits from 60 to 600, these laps are recommended for faceting, cabbing, rough grinding, and fine shaping, offering superior efficiency, precision, and reliability from the first facet to the last. Perfect for professional gem cutting, jewelry finishing, and advanced lapidary work, the sintered diamond faceting laps ensures smooth, accurate results and exceptional value over time.
