20pcs Solid Carbide Burr Set 0.118‘’（3mm）Shank Tungsten Carbide Rotary Files Burrs with 3mm Cutting Head Diameter Fits Most Rotary Drill Die Grinder for Woodworking,Engraving,Drilling,Carving

Works very well on soft materials like wood and plastic, haven't tried it on soft metal yet but i guess that it's not efficient enough but it's good for what I want it for... Note: shank is too short

Really fun to use if you like power carving old man faces in wood.

I bought this for wood carving. Compared to buying from a store, these are as good quality but far less money.

Worked great. Broke a snap on m6 tap off in Transmission case. Ground it out with a ball tool.

Bought a new piece of real estate and almost ALL the doors didn't shut properly due to misalignment on the latches/strike plates. I used these on my Dremel to file out a bit of the plates and it worked great. Amazing value, you should buy a set.

These little guys are great. They hog out material pretty nicely and fit into a standard rotary tool. I have made hundreds of cuts and material removal on steel and aluminum and they are still very sharp. When cutting steel the metal slivers these produce are very sharp, tiny, and get everywhere. Watch what your wearing as your clothes will get embedded with tiny slivers. Spent hours getting slivers out of my hand one time because I was wearing fabric gloves.
