10pcs Carbide Burrs Set, 1/4"Cutting Diameter 1/4"(6mm) Shank Diameter Double Cut Solid Carbide Rotary Burr Set for Die Grinder Drill, Metal Carving, Polishing, Engraving, Drilling

definitely worth the money just don't get crazy pressing on the metal while grinding let the bit do the work and you will be very satisfied

The heads seem to be uniform with no obvious defects. Haven't had the chance to use them yet. Price is good however they are made in China.

Works great for grinding off paint and rust in tight spots. Also the time savings on filing your finger and toe nails is worth the purchase!

I needed to extract a bolt from the frame of my car. Ended up snapping a hardened bit in the bolt while drilling it out, so had to result to using something harder. Enter these burrs!They made short work of cutting through and around the broken drill bit, leaving me free to finish removing the broken off bolt. There was no sign of any dulling on any of the bits I used.While I hope I won't need them again, I know I will. And the knowledge they will work when I do need them is reassuring.

I've only used one burr, but it works great and it's still as sharp as the first day I used it

It is not uncommon for me to buy tools I will/may use at some future date. Could be up to 6 month possibly. However, inspection of some of the anticipated use burrs seems to bode well for them as the cutting edges are very precise as would be expected on a carbide burr kit. They were delivered quickly and I have great hopes for them when the time comes. At this point I must give them a 3 for the good qualities I found but cannot go higher because I have not actually used them. However they perform in future will determine how I modify this review if ever.

These were a gift for my husband and he used them immediately and said they were perfect.

Cant say about durability yet only used em a few times but they seem like they will exceed my expectations. I'm no professional but I have very high standards with tools
