Frequently Asked Questions
Q: What grit size should I choose for grinding gemstones on a flat lap disc?
A: For rough shaping of gemstones or rocks, start with a coarse grit such as 60# or 120#. For intermediate smoothing, move to 220#–600#, and for fine polishing and a smooth finish, use 1200# to 3000#. The wider your grit range, the better the final surface you can achieve on hard stones like agate, jade, or quartz.
Q: Can this 6" diamond flat lap disc be used with water?
A: Yes! This disc supports both wet and dry grinding. Using water during operation is highly recommended — it helps flush away grinding powder, keeps the disc cooler, and extends its working life significantly.
Q: Is this diamond grinding disc compatible with standard lapidary machines?
A: Yes. The 150mm (6") diameter and 12.7mm inner hole are standard sizes compatible with most flat lap grinding machines. It can also be used by hand on a flat surface for smaller or more detailed work on gemstones and carved pieces.
