PHYHOODiamond Burr Bits 2.35MM Diamond Drill Bit Glass Small Pipe Deburring Rotary Tool Accessories 90 Pieces

The package and casing around the bits arrived pretty crushed making the cases unusable. However the bits themselves seem to be of good quality and would have cost 2-6$ per individual piece at most hardware stores. I was a little disappointed when I realized it was a 3pack of the exact same bits in each case but not a big deal. I'm sure I'll use the extras after grinding them for a while....all in all its worth it for the price. Even with the damaged packaging.

Great set of 90 various drill bits for your Dremel (at least that's what I've been using them in), and they've worked just like I've wanted them too. So far I've been able to use them for a wide variety of projects. With spring around the corner, I'm sure I'll be testing them on other things, but as of now, a good buy, for a low price, especially if you're trying them for the first time.

There are quite a few Burr Bits in this set, and I'm happy with the results. I've tried drilling through a few stones and crystals now, and have good results...but the burrs have worn down after a couple stones each. Still worth it due to the affordability, but worth considering.

Not a bad buy for the price. Make sure to be aware of the size; I needed to buy a collet to accommodate for the smaller size shafts. No complaints about the actual product so far, just in my own lack of product research lol

Great value and I would buy again.

I go through dozens of these every couple of months in my glass etching and these by far are superior to any others that I’ve used. There are many more “bits” here that I actually use instead of numerous bits that I never use when etching. (Anybody need about a thousand unused barrel bits? I can fix ya right up.)

these didn't work in my Dremel I had to get a new connecting piece afterwards they were fantastic

No instructions. I thought these would work with the dremel-type tool I bought from Amazon, but I don’t know if they will or not. Maybe I’ll have to get a different size collet?
