Rotary Burr Set, 10pcs Tungsten Carbide Rotary Burrs Set Double Cut Points Files Grinder Cutter Fit Rotary Tool for Engraving Wood Working Carving Polishing and Drilling, 1/8" Bit Shank 1/4” Head Size

Excellent quality, worth every penny. Very robust

For the price these have performed extremely well. I have used them in an air powered die grinder to dress welds that couldn’t be reached otherwise. They have cut very well and still appear sharp. Given that they only have a 3mm shank you have to be a little careful about how much pressure is applied when cutting but since they are so sharp you don’t need to apply that much force. Overall very pleased with them.

Good for wood.

The first thing that comes to mind is that the most important aspect of the tool is the ability to use it to create a unique and useful product

Excellent for carving which I wanted them for.Good value for money .I would recommend these burrs.very pleased.

Used this to clean up some welds on aluminum with a Dremel. Did the job incredibly well, had to clear off a good bit of metal and bits were still sharp after.

Did the job

Look good but poor quality - they bend easily and also get blunt very easily, too.

my first time using these burrs and I must admit they perform quite well

One of my burrs had a bent shaft. I sent a photo to their support email listed on the box, David was great and sent me a replacement right away. I used these to grind out a broken easy-out, but they are great for all sorts of work. Can’t beat the price and seem to hold up alright.

Funcionan perfectamente, excelente producto

Good value for the price, it's hard to find good quality rotary cutting tools in this size. These are ok. Work slowly with light pressure.

I thought these were going to be useless like so many other cheap China made products which fall apart when meeting any resistance. But one of these I have been using and have grinded decently thick metal as well as other things. Have only used 1 bit so far and it's still going strong.
