Lukcase Diamond Coated Grinding Dremel Review

It was great. I bought two sets and haven't opened the second one yet. I have successfully carved river rocks, concrete and various rocks. they hold up well.

Bits last less than 5 minutes UNDER WATER, the diamond-holding coating wears out in less than 5 minutes, even with water cooling. These bits are GARBAGE. If I could give ZERO stars I would spend my money elsewhere!

I bought this kit to repair grout on ceramic tiles. I haven't used them extensively, but they rubbed the grout without difficulty. So I would say that they have excellent cutting ability. I can't comment on durability as I've only used it for a few minutes. The variety of shapes is very helpful.

These bits are designed to sharpen in 3-5 minutes at recommended speed. The wheel size is the best they have. I do stone carving as a hobby and can usually complete a few projects with a bit set of this size. I've only completed one project with them and I've been lucky. Oh, and forget to sharpen them.

I have to say the best deal on diamond drill bits. I have found fantastic quality at a great price, used some watches and they look and work like new. I don't know if I ever will or need to have more, if I do I will get more of it. I find it really hard to put into words how amazing this product is. I have used them on a tiger eye stone with great results, only the ridges I found remain. I don't see how spending that much more money could make me a better person, no reason to even try a few…
