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.

Gets the job done.
I picked these up for an art project and they worked great. I picked them over a Harbor Freight pack since they were 1/4 the price. They held up well and allowed me to carve with good detail. I had no problem fitting and using them in my Dremel.

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.

20pc carbide burr bits Amazing
Incredible never owned a bit that could grind/drill straight through steel bolts. They all took a beating with no breaks and all still grinding. I used many as I had other bolts seized and broken. You have to take your time they won’t break unless you’re a moron. $20 very very well priced for the quality Lowe’s doesn’t even have this stuff I’ve never seen it

Designed for rotary tools
These carbide bits are small. They are meant to be used in rotary tools like the Dremmel. I wouldn't recommend using them in a high speed die grinder. I have larger carbide bits for that. Keeping this in mind, they perform very nicely in a rotary tool, grinding through steel with no problem. They are especially good for cleaning up narrow welding seams.

Good selection
Get these if you need to grind/shape metal. Its the right tool and makes much quicker more accurate modifications than that old drill bit you were trying to use for the last 2 hours.
