Works great on all natural materials * Ceramics, Tile, Glass, Bone and Wood * Great for Carving, Grinding, Sanding, Etching and more * Long lasting when coolant is used * Made in China Set of 30 cutting burs 1/8-Inch Shank, 2 Class Diamond Titanium Coating. Use for ceramics, tile, glass.
I bought this item to use for my jewelry craft items. With these bits, I can drill small holes through seashells, beads & glass without chipping. The bits work perfect in my Dremel tool. The diamond part does wear down after drilling a lot, but for the price I think it is a great deal & it gets the job done.
The burs are fairly sturdy. If grinding and shaping remember to keep moist with water or lubricant. Otherwise you rip off the diamond surface (did this, not thinking). Some of the finer bits break easily, but the rest do the job.
This is a very good product. 30 is a lot and it covers all you could need. I work with silver and have a drill stand in the club and often need different sizes so this was ideal.Packed very well to be able to see just what one you need at the time.
