Carbide Burr Set 20PC 1/8" Shank – 3mm Tungsten Double Cut Carbide Rotary Burr Set for Metal and Wood Carving, Grinding, Polishing, Engraving, Drilling.

I didn’t expect much in terms of long life, but I have been impressed thus far. I’ve used them frequently over the few months I’ve owned them. Have not had any issues. Always sharp, not bad for the price. I don’t use them everyday so I don’t know if they’d handle daily use well. For the occasional user I would recommend.

Perfectly inexpensive die grinder tools.

Used a couple of them yesterday and like them. Also like the clip on the side of the case, just clipped it over the side of my toolbox. From the looks and what little use I've had with them, probably best with mild steel and softer metals. But satisfied with the purchase.

Smaller than I was thinking and bounced around a lot on wood. I recommend diamond tip for removing old polyurethane on wood.

These work really nice. No issues so far.

For the money they do a great gob, i use these bur bit in my shop at home, they cut and shape fast and its nice that they come with a storage container. i will buy more when as time goes on.

Carbide Rotary bits worked well. Super hard steel, worked well on mild carbon steel. Would buy again.

Not the best by any means
