DerBlue 50 Piece Diamond Gemstones: Perfect for Lapidary, Beading, and Jewelry Making Review

Great set, the bits I use the most seem to be pretty good. Ideal for drilling glass and ceramics.

OK for the price, you get a lot of choice. I use them when carving, they tend to be misaligned and some of them are real wobblers. Most of them are usable, but I have about 10 or 11 that I can't use because the jiggling is too much.

I love the large selection of millstones and the box to keep them. The way they are stored in the box makes it very easy to find the exact drill I need. The downside is that there is no chart in the kit explaining what each drill is for.

I find there is a wide range of cutters, the only thing I have to say is that I find cutters wear out very quickly. But I think they will all run out quickly, so far I haven't been able to find any that don't exist. If anyone knows if there are burrs that last longer let me know .Adam'sAdamsroy@hotmail.com

Good selection of diamond burs. I use them with my Dremel tool. Be sure to keep the workpiece wet during use to avoid clogging. I highly recommend using them with a flex shaft rather than using them directly on a Dremel tool. The flexible shaft gives you far more control than having to hold a large, unwieldy Dremel. I love the little box. Keeps everything nice and organized in my tool closet. It's easy to quickly find the beat you want.

Really enjoyed working with it! I carved the text into a block of limestone using a dremel at speed 6. Great. Also, I was able to drill nice big holes in some of the antique architectural glass blocks using various drill bits. Make sure you have a spray bottle filled with water to frequently spritz your work surface on the tops of the ridges. This is absolutely necessary when using diamond drill bits and milling cutters. Otherwise the drill will get too hot and the molten diamonds will break…

I bought these to make drainage holes in small ceramic and glass containers to make succulent pots. I really liked the different sizes, which seemed like good value for money, but I found them faded almost immediately. I don't think I could make a single hole even in soft ceramic with a single drill bit. The bits I usually buy, which only come in one size and three shapes, create at least 10 holes and sometimes more before becoming dull. a bit, I would skip it.

Works great! Use them to drill holes in sea glass. They seem to work just as well as the official Dremel bits, but the only downside is that EACH of these bits broke out of their plastic box/container and ended up floating in the big Revain cardboard box. some were even under the box flaps and ready to fall through the cardboard box. I was AMAZED that I was able to find all 50 pieces and none have broken out of the box! Revain should at least seal these bit boxes with a plastic lid so they…
