Tools and Hardware Reviews of Pro-Quality 20-Piece Diamond-Point Bit Set for Rotary Tool - Glass, Stone, Ceramic
Customer Review: Very usable set of points. Awesome price.
Summary: 4 Stars
I got this kit when the similar few bits that came with my mini-tool did not have the profiles I needed. I wanted to write more information on the back of my kitty's tags, such as alternate phone numbers. This kit gave me the choices I needed.
The end tip of the bit I used was a little out-of-center from the shaft, but I found if I wrote with the bit tipped like a normal pen, instead of straight up & down like a drill bit, it worked pretty good.
Most of the other bits seemed more uniform. This kit does the job I need, and is an awesome price. If you are looking for very high precision items then I think you should first start with this kit, because you are going to pay more than what this costs for each bit otherwise. But if you only want the best, this may not be for you.
Customer Review: Went through the hardest manmade material in the world!
Summary: 4 Stars
I broke an ez-out off in a broken exhaust manifold to head bolt that was stuck in my cylinder head. All the hardware stores around wanted $10 for ONE BIT! Now I will say it took quite a bit of time but with only a couple of the bits in this kit I went through a good 0.5-0.75 inches worth of hardened carbon steel, and they worked great with just a simple electric rotary dremel tool. As long as you know what you're doing, and you take your time, and don't force anything these bits should be able to go through just about anything!Customer Review: eliz1354

They work really well. My biggest gripe is that I've been using them for about a week and because I am drilling sea glass and stone, I have to use water. The bits I have used so far are already rusting. They are so inexpensive, and there are so many, I'm sure they'll be dull before they snap...we'll seeCustomer Review: Pro-Quality 20-Piece Diamond-Point Bit Set

I feel the Pro-Quality 20-Piece Diamond-Point Bit Set may not meet a jewelers highest demand for Pro quality, but it will suffice for the price to allow you to have a diamond point to use when you need it at the workbench. Good enough for the price paid.Customer Review: OK for soft materials
Summary: 3 Stars
The drill bits worked fine on soft materials such as seashells as long as I didn't put too much pressure on the bit. But on harder materials such as ceramic or stone, the diamond coating wore off very quickly, rendering the bit useless. And yes, I did use lubricant.
