1/8 inch Carbide Burr Set - 10pcs Aluma Cut Carbide Rotary Burrs for Aluminum 3mm Shank Fits Die Grinder Drill for Woodworking,Drilling, Aluminum Craving,Engraving, Polishing

These worked great for grinding 6000 series aluminium. I can’t attest for any other metals, but it worked much better than I had expected for my application. I don’t hand out 5 stars often, but this product is legit.

Great quality.love my purchase..

I used these to modify an aluminum intake manifold, and they worked amazingly well compared to the myriad of other tools I had tried. I even used these on some steel parts of the car when clearancing a couple of things. It cut the steel well HOWEVER the shavings that came off were literally like a million tiny needles, so BE CAREFUL! I had to use a magnet to clean up the driveway, and ended up throwing away the shirt I was wearing because it became an inside out cactus... None of that is the product's fault, and these are really good, just be smart and wear protective gear whenever you use stuff like this.

I purchased these bits to port a 196 Clone cylinder hear . These bits remove aluminum well but are very hard to control . You will be porting along , the bit will "catch" and it flings the rotary tool off in some direction you were not expecting. I had this happen and it damaged the valve seat . Not cool . They do cut well though .

Good quality burrs. Just what I needed for working and modifying wooden pistol/revolver hand grips.

I bought these to port my intake manifold. They have worked well and show no damage or wear

Needed a set of smaller bits to do some more intricate porting on some heads on a pencil air grinder, these worked great.

Almost perfect. Sharp and well designed. Aluminum flies off the piece, the flutes stay clean and nothing gets hot. BUT the shafts bend. I was hardly applying any force at all, and the shafts were bending. Very strange, because they're quite well designed except for that.

I previously had used the style of bit with crosshatched teeth to cut aluminum - they end up getting clogged and becoming useless super quickly. These ones had no such issues, just kept cutting until the job was done. Great product

Very nice handy bits just thought they had a bigger shank when I ordered them. I’ve been using them in my cordless drill to clean up some aluminum welds have to redo for a customer. They work great!!

For the price these burrs work fine. I use mine mainly on wood so they seem to hold an edge fine
