For these burrs if you are a jeweler and trying to set round stones, these bits are absolutely awful. None of the sizes are correct apart from the 2.5 mm. There is no 3 mm, there is 2.4, 2.5, 2.8, 3.4, etc. All of these bits are at least a 10th of a millimeter off. Do not waste your money.

These bits passed all preliminary testing and now we wait for the durability test that will take a while. So far, so good. We will update if anything changes. Initial impression is positive an I can recommend them specifically for price and apparent quality.

To this point I have not been able to use this set of diamond abrasives. The shafts are too small to fit any of my drill chucks. As soon as I figure out how to mount them in my drill press I will be able to control the cutting action by holding the workpiece with both hands. It will be very useful to use magnifiers to follow the patterns desired.These are intended for very fine work. I wanted some way to engrave my name in a small area of cutting boards and small wood projects. People have asked me often if I could sign the boards. It is my intention to engrave my signature and then fill it with epoxy. Sand it flush and make everyone happy.These bits are about 1-1/2" long (see photo))The mfgr's description was not clear as to the types and sizes of the tools these work in. If you are wondering if a drill chuck you have will grip these; try using a 4 or 6 penny finish nail as a test.I will find a way to chuck these into something I have.The bits themselves are well built and good material. Good product

These burrs arrived sharp. We are using them in our shop to create, carve, and refine very small details in the architectural models we build.

There aren’t any 4mm+ etc bits it’s just a few tiny ones around 2mm. Get a different set if looking for or needing a 4/5mm etc

Had potential to be a great buy, can't use it with the right size included
