20PC Carbide Double/Single Cut Burr Set - 3mm Shank, Rotary Tool Cutting Bits - Accessories for Dremel, Fordom, Flex Shaft, Dewalt and Multitools - for Wood Carving, Metal Working and Engraving.

I was so disappointed when I opened this little box. The bits looked small and breakable. I figured I would go ahead and use one just to see how long before it broke or wore down to nothing. I was amazed ! That little bit went through the tin like butter ( only a slight exageration !)They have performed spectacularly. I love them. Great value for the money.( They want me to use these words. )I'm amazed at their durability. Their words but very true.

The bits work well, they were reasonably priced & delivered quickly.

The few that I have used the cuts are smooth.

Unbelievable product. Shaves away metal work with Dremel like butter. Very happy with this purchase. SO many bits to choose from to use for different jobs. Thank you.

This is what you want to get them crazy exhaust bolts out or if you broke that drill bit off in it and need something awesome to get it out

They seemed like the burr bits would be bigger but they have super small heads. I used one of the bits and it broke off and both the top and bottom pieces flew out of my dremel. I tried multiple dremels and rotary tools with these and seemed like they were not 1/8 inch shanks because slipping issue. Most of the bits chipped right away. I used the owners manual recommended speeds and still same issue. The single cut I really liked but they are dull now after a few uses. My most used material for these are on steel and welds. Also, brass, copper, and aluminum. Longevity wasn't substantial and durability is not that great. Shafts never bent but they burn up quick even with cutting oil used with them. I hope the manufacturer can make this right...

I was able to use one of these carbide bits in my mill to cut the core of a broken bottoming tap out of a blind hole without cutting the remaining threads. The bit didn't even get dull at all! Much cheaper and easier than the 3 tap removal tools I destroyed first.

WOW... these are fantastic. If you want to up your game with a Dremel tool, these are the bits to use. Very solid and extremely well made. They cut through extraneous material like a hot knife through butter. The differing profiles let me trim darned near any shape with ease. More expensive than other bits, but worth every penny. A joy to use.

Tienen muy buena calidad y llegaron antes del tiempo marcado.

I am wood carver an wood worker. As soon as they came I put them in my Dremel an started carving. I used them on old dried piece of 2 " grape vine. (Hard stuff) they worked very well. Had to crank my Dremel to 11 for the fine sharp bits, but they worked. They seem to hold their sharpness. Seem pretty durable, so far. Good buy I think for small intricate detailing an finer carving.

Great product at a good price

Great little set to work with wood or metal. Cut well and stay sharp for a long time.

Good quality burrs for my wood engraving projects.
