Carbide Burr Set 10pcs JESTUOUS Double Cut 1/8 Inch Shank with 1/4 Head Tungsten Carbide Rotary File Burs Bit

So far no problems and work great . I've used them for a couple months now and use them on the regular no seriously issues with them so far .

I've used these burrs on both a dremel and a hand drill and have been pleased with the quality and they seem to manage heat well.

I've only used them on aluminum but they worked very well. I used them on my makita drill which does not produce the speeds a dremmel does and they still worked well.

These things work amazingly well. I'm really hard on bits and these ones have not disappointed me on bit. I do a lot of artwork involving bone haven't had any problems at all

Look good but that is about it. Finally went to use one today and the supposed tungsten it is made from is quite soft. It would not even grind into the aluminum material I was hoping to be a simple job with these. To bad.

Had one of these bend into a banana shape using on a high dollar dremel wit careful use

Bits are larger so removal of material is faster, very useful and are not provided in the usual Dremel kits.

Good selection and basic burrs. Works well in my gourds.
