10pc Carbide Burr Set 1/4" Shank Tungsten Double Cut Rotary Die Grinder Bits - Cutting Burrs for Milwaukee, Dewalt and Die Grinder Accessories - Wood Carving Metal Working & Sturdy Storage Case

I have found no issues with these. They work as intended. They are Sharp and they do the job well. Definitely a good price for what you're getting.

Very sharp and durable

These are a fraction of the price of some of the name brand burrs and they work great for the work I use them for (light duty commercial work).

Hope they last.

I bought this set to do some clearancing on a transfer case driveline yoke, as well as other future jobs. The barrel burr that I used chewed through the yoke metal like it was butter with no visible wear to the burr; had to be careful not to remove too much material, due to the speed it would remove material! There is a nice selection of shapes with this set and this should last me for years with the types of jobs I'll use them for. Time will tell how long they will ultimately last, but based on what I've experienced, this will probably be the last set I'll ever need. There are cheaper sets out there, but this seemed to have a great price point for the quality and selection of the burrs this kit presents.

I’ve been trying to bore out a hole in 1/4” CmV steel. Drill bits? Nope. Way too slow. Bought a cutting burr from a local Ace Hardware, that said it was for steel. The burr quickly got dull, and rounded off before cutting any of the steel on my project. Decided I’d wait for this set to come in, and finally got after it again today. To go from 7/16” hole, to ~11/16” took all of about 90 seconds, to 20 minutes to bore it out!! After my experience with the burr from Ace, I wasn’t feeling very confident. These birds are AMAZING!!!!! I can’t really speak to durability yet, but I feel like they’re going to hold up pretty well! Once these burrs are ruined, I’ll DEFINITELY buy from Taita again!

These are great carbide burrs. Perfect to use on an electric die grinder and chews away mild steel faster than my more expensive, albeit more worn out burr. I think these burrs hit a sweetspot at around 10krpm where you need only minimal force to cut efficiently. This comes with a variety of grinder shapes from ball, cylindrical, and conical of various sizes. Overall a very impressive set at a reasonable cost. I'll be curious to see if these hold up over the next couple of year, but at less than $3 a burr I'll be happy if they last the next year.

i bought the single a few weeks back and loved it so much i came back for the pack! these work great in my dewalt cutoff tool for all types of materials. wood, pvc, aluminum, mild steel and anything inbetween. i do recommend a face sheild and gloves over goggles since they tend to throw alot of "man glitter" but they cut though material with ease. almost no pressure needs to be applied to cut or shape your material and if you "dig" with it you material will be cut rough and it will harden steel and dull the tool.

Good bang for the buck, well made

Buen juego de limas, excelente acabado. Te dan un año de garantía con Amazon. Buen precio con relación a las diferentes marcas vendidas en México. La variedad de formas en las 10 limas es excelente. Su estuche lo hace muy práctico para no perder las limas.

Without a doubt, this has been the best brand of rotary burrs that I have purchased and used. I had already purchased this brand and noticed that it surpassed all the ones I had used previously. The only problem this time is that I bought 1/4 and they sent me 6mm. but the seller was willing to resolve the problem. These are the most expensive on Amazon, but they are worth every penny. The quality justifies the value! I will buy more often. And I recommend it to anyone looking for quality in the finishing of their work.

Great carbide burrs, sharp and long wearing and at a great price too. Be aware that some cheap carbide burrs state that they are 6mm, but they are some 50 microns short of 6mm and that is a huge difference, because they will slide off while in use, so best to stick with a trusted brand and pay that little bit more.

I used one of these bits today to remove some bad amateur welds on 1/4" angle iron. It did the job quickly and shows no signs of wear. I would have been happy if i sacrificed one of the 10 bits today.Good assortment of burrs and the shafts are a good length.No reason to deduct any stars.
