Carbide Burr Set, 8Pcs Double Cut Tungsten Carbide Rotary Burr set, 1/4 inch Shank Die Grinder Bits, Carbide Rotary File for Metal Wood Carving, Engraving, Polishing,Drilling

I needed a bit to grind some bolts down to be able to remove a part. I used one of the taper bits to do the job. After grinding several bolts it did look a little dull but still seams like it should work on the next job. Maybe I should have let it cool down between bolts but I needed the job done fast and didnt care about the bit. So to me it was worth the money.

I was not sure if this would last cutting steel. I do a lot of steel work. I was so impressed that I ordered a second set as a backup!!! I would recommend these to anyone.

These really chew through the aluminum and help hide my my merely adequate Tig welding skills. Only thing is that the aluminum really likes to stick to these so be sure to give the burr a quick spritz of wd40 before using. I would say I'd buy these again, but I probably won't need these again unless I lose them in the pit I call a shop. Great value for the money.

The carbide bits worked wonders did its job

Reasonable price, worked great, delivered on time. i would purchase from this vender in the future

Really like the sturdiness of the product. Plus it comes in a nice plastic case.

Never had a bur set, always used stone bits. Should have located some sooner. Try enlarging a hole with a stone. I thought these would feel sharp, but no. Cuts okay. I'm just using die grinders and finally had something that could use the 1/2' cylinder cutter. It had a little vibration in all die grinders I tried it in so it must be off somewhere. Just bought a rotary rasp set, they don't work as good on soft material as these and these handle steel too.

Thought you should know before buying this product that it's potentially hazardous to your safety. I was using it to reem open a hole a little on a piece of regular carbon steel. I mean that's what it's used for. upon making contact with the steel, it fragmented. I couldn't piece big enough to add to the picture. The shank (to the right in the picture) was the only remaining. Scary stuff, and good thing I had my safety glasses on. So, buyer beware. Too late for me to get my money back, but I can save you yours.
