I am a wood carver and use these various burr cutting bits to shape intricate areas more accurately than I can with a knife. I use these in my variable-speed Dremel rotary tool, and they work great. These bits are very sharp and cut well at a properly controlled speed. Because these burrs are sharp and closely knit. I use a toothbrush to clean the bit. *Remember to wear eye protection, and I do wear a respirator because of the fine dust it can make*.

Just when I thought a few of the 'bits' would do, I chose this set with a wide range of sizes and shapes. These have proven to be more useful than I expected, are durable, cut cleanly and are a great value for the money.

I used these to grind down welds in order to get a harmonic balancer off of a crankshaft. Works excellent when I used it with a dremel tool on the fast speed. I expected them to wear down from it but they held up with no wear. They’re sharp and stayed sharp.

Nice selection of bits for many different jobs. I am a hobby machinist and fabricator. This set should come in handy for deburring and cleaning up welds. Also, for shaping wood. There are a lot of different shapes and sizes for a reasonable price but probably best suited for wood projects. I will see which ones I use most frequently and replace those with a harder material for my metal fabrication projects.

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.

Ok I nor mally dont do a review but these little guys do work. I needed them to finish a aluminum bracket that I'm using to mount something on a vehicle. Aluminum 1/4 inch plate these ate thru it like nothing. For the money spent their well worth it!

This is a great set of burrs that fit into a Dremel tool. I had tried to use a Dremel grinding wheel and it was taking forever to do what I wanted. With these it took a couple minutes to do the job. The 2 burrs I used held up and still look new.
