JINGLING 7 inch Lapidary Blades Thin Diamond Saws Blade Trim Rock Gemstone Cutting Saw Jewelry Tools for Stone

I love most Joiner products. I use a lot of their polishing lap discs, but this is not a good saw blade. I got 3 thumb very small rocks cut and the diamond is gone off of it. Very expensive 3 tiny rocks. I was concerned with the lack of diamond on the blade, it was very minimal. Do not recommend at all.

Parece que este disco ya fue vendido y devuelto una vez por otro comprador. ( Venia con el comentario en ingles que no sirve) Me siento muy engañado y no puedo creer que Amazon vende basura como esto.

4.5 out of 5 Could be a little cheaper probably but the profit vs cost/precision of this blade is worth it. I use this blade to cut small .5-1 inch quartz geode agates. I am able to cut about 100 before the blade becomes too dull to work with safely. The blade does not say it is rated to use for quartz and for those who don't know. Quartz is very hard. If this blade can stand the test of cutting these geode agates without smashing them open. I would say the description for this item is accurate. This blade is for TRIMMING and fine shaping softer smaller minerals. It will not last forever, it is thin and the blades diamond layer is only about 3mm. A small Dremel blade would be cheaper and has more diamond cutting space if you are looking for a cheap alternative. If this blade seems like it is worth the money for a specific project, trust me, it is great for small pieces. If it works for quarts when it is not graded for it, it will work for trimming smaller softer material for a while if you are patient and using the right tools. TLDR This blade is great if you can read the description, are cutting the right material, have the right tools, knowledge and patience to utilize the blade.

By far my favorite blade to cut agates with! I have always hated losing so much material when using a standard blade. This thin blade cuts amazing!

I gave it four stars because of the price and ease of use. It is a very basic easy to use lab dairy blade but will not last long. This is not what you're going to use to cut a bunch of lake Superior agates and expect your blade to still act like new. But it's perfect for trimming and softer rock, will work on quartz but we recommend softer stone doing a lot of cutting.
