Carbide Burr Set with 1/4''(6.35mm) Shank 8pcs Double Cut Solid Carbide Rotary Burr Set for Die Grinder Drill, Metal Wood Carving, Engraving,Polishing,Drilling

I certainly don't expect much from most of these made-in-you-know-where tools, but these actually work really well. I used one to grind a larger bolt opening in the shock tower of a car. The steel was pretty thick, and this did a great job in short order. Ported an exhaust manifold with another and it took no time at all. I've used several of them multiple times by now and they show no real wear. Very happy with these.

These work really good. They great to have on hand. Cut probably better than any I've ever tried

i'm impressed with the quality and the way they cut for the price ya can't beat it!

Works as intended. I’m satisfied with the quality to price ratio. Working good so far. Hope they don’t get dull soon as they we’re pretty cheap.

Have used these sporadically since I bought them about 3 years ago. Had to grind out a bunch of MIG tack welds yesterday and was very impressed at how well they cut (fast!), how easy to control in steel, and how little damage I did (even in inside corners where it was hard to control chatter). A few tiny chips - sorry, no pictures - but I think that is down to me letting it chatter a bit. Definitely recommend and would buy again.

Good set of metal working burrs

These bits are perfect. They are sharp and seem to be staying sharp.

I bought these burrs to clean up some plasma cut holes on mild steel plate. After cleaning up two holes I noticed several teeth of the burr are chipped. It did remove material quickly but not sure how long they will last.
