Appear to be high quality. I used one immediately in my Dremel to enlarge a cutout in 1/4" aluminum plate. It cut with ease and remained sharp.

These burrs cut well and are hard wearing. Other burrs made from softer metal are blunt after a few cuts when I am working with extremely hard wood such as gidgee and buloke.The teeth are coarse and give a deep fast cut to remove material but the finish is rough. It would be good if one or two had finer teeth for finishing prior to sanding

These little suckers work great. I have been using them to blend welds in stainless steel and the rotary burrs cut the metal without any issue. They seem like they will last and I will get my money's worth out of them.

Broke on fist jobDisappointed it disintegrated so easily
