    • 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.

The media could not be loaded. 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. ... show more

    • Aggressive burr bits!
I bought this little set of attachments for my Dremel. I’m working on making a bowl out of a small stump and needed some smaller tools to get into the nooks and crannies. They are very aggressive to help clear out the rough sections and being a bit longer, good at getting into the tight spaces to get things cleaned up nicely. The set comes in a small plastic case that holds everything nicely. When you order it you might think it’s going to be bigger than what it appears online. The plastic box is maybe 3” by 3” so don’t be surprised when you get it in your hands. Solidly built. Should last a long time. ... show more
