Durable / stays sharp
very good quality. I was impressed and very happy. i started using them as soon as they arrived. Very good range of shapes and very sharp and durable. I have used them alot and they are still staying sharp and carve very well. I will be buying another set with some different shaped bits.

Nice Set of Small Burrs
These work well in my rotary tool and appear to be well made. So far I have tried them on plastic and aluminum, and they cut like butter. Haven't tried them on harder metals but since they are carbide, I would expect them to work fine. Nice assortment of shapes and sizes.

Excellent Carbide Bits. I Would Highly Recommend.
These carbide bits are wonderful. They are my new favorite thing for grinding metal. I have had exhaust pipes stuck on my motorcycle for a good 3 or 4 years. I had tried a variety of methods to cut the the flange and bolts, with no luck. Then I found these carbide bits. I researched a lot of the different ones, and these are the best. They do not break if you use them correctly. One important thing is to make sure you have inserted them completely into your rotary tool. I used the rounded bit in the video for about 4 hours before I switched to the pointed bit. The pointed bit worked much better for the exhaust flange and bolt I was grinding. It took me about 9 hours total, which would have been quicker had I used some cutting oil on it. They do work and are solid and good quality. Mine have stayed sharp despite grinding hours with just one bit. The other photo with the black post was a hole I was grinding out to fit two pieces together. That's the same bit I used to grind both exhaust pipe flanges and bolts down and it's still very sharp. I would Highly Recommend these Carbide bits. Lots of reviews say they break, but that's because they were probably not being used correctly. You must insert them all the way down into the rotary tool. These bits are very easy to use and have many uses making it a wonderful addition to any tool box.

Was skeptical but they work great!
These work great. I was skeptical and usually donโt write reviews buts these burrs work amazing on hard metal. Not sure about longevity but at the price point, Iโm not too concerned. Very happy with these.
