eoocvt 50pcs Diamond Tipped Coated Rotary Grinding Head Jewelry Lapidary Burr Grit

These nuts are phenomenal for removing material they're the best ones I've ever used

Box is perfectly sized to hold tips - be careful to keep the yellow guard in its position and not to lift it up, or the bits which are narrower than their shank are likely to fall through the holder... Into the convenient box. A nuisance at best. My set has seen plenty of hard use on natural/found stone, mostly quartz and granitic gneisses. Nothing soft. Rarely is overheating an issue, and my "go-to" flat-edged wheel (first row on the left, third one from the top) for grinding comparatively large portions of stone for pre-shaping has as of its last use stripped off half of its diamond coating on the narrow edge. I probably could have avoided this using more lubricant, water bathing, and other efforts, but the bit took its use like a champion. The range of tip shapes allows for a great deal of versatility in the shaping and sculpting process, and this set is indispensable to anyone working with natural stone, brick, ceramic, tile, glass, or any other material for which nothing less than diamond will do. I am likely to purchase another set long before the wear on the bits requires me to buy a new one, because these do their job so very well that you can't have too many. That said, for some types of work (less grinding/shaping/sculpting, more engraving/linework) you may want to purchase a separate set. The tools not being able to do something they're not meant to do doesn't diminish their incredible value. DO NOT PASS ON THIS SET. It is a worthwhile investment. I can't speak highly enough of the product.

Fit my desktop dremel great. Work as they should. Tried them out on my wood sculpture. Worked well. I like that they come with a holder so everything stays in its place. Great buy.

These just grin away on my rocks. I love the multiple shapes. I really like the case too keeps them organized. Seems like good quality but haven't really used them for very long.

This set is great. I like the variety for grinding or carving different surfaces. Works great as a wet tool, but not so well dry. To keep my Dremel out of water, I just repeatedly rinse the stone. It’s a slow but precise process. Will buy these again.

Decent tool for the price, somewhat balanced. The description is correct.

These diamond bits, fit perfect in my dremels, they work perfect, they last a good while ( keep in mind if you are working on stone, they will last longer & work better if you have a constant water drip on your piece while you work!) Lots of different bits in one case.

Quite impressed for the price! Definitely don’t last a LLOOONNG time. But they do the job. And well worth the money!
