Good deal for the priceMar 12, 2009
By Charlie Howard
This set of 20 bits costs less than one high-quality diamond bit from other sources, and the bits did the job for which they were purchased.
Used them to drill two 1/8 inch diameter holes in non-tempered window glass. This must be done slowly to avoid overheating and possibly fracturing the glass. Used several different bits to change shapes in the hope of making it go faster. When done, the holes were fine and all of the bits still seemed to have their abrasive surfaces.
I've read elsewhere that a high-quality diamond bit will last for perhaps three holes like these, and that it takes about two minutes to make one hole. Well, it took about 30 minutes per hole, but more than half of that time was spent pausing to let the glass and bit cool off. Since all of the bits still have diamond grit on them, it seems likely that they'll be able to make several more holes before wearing out.
NOTE: Tempered glass probably will shatter if drilled. This window didn't have a "tempered" logo in the corner and looked normal when viewed through polarized sunglasses.

 Pro-Quality 20-Piece Diamond-Point BitJul 03, 2008
By Nancie Johnston
Very nice drill bit set. Seems to be of good quality.
I am using the diamond bits to drill semi-precious gems.
One bit has lasted three gems, so far.

Very usable set of points. Awesome price.Dec 29, 2005
By Karen F. Hensley
"kfh"
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.

A must buy for Crafty people.Jun 23, 2008
By Derek Slaughter
One of these diamond tipped bits will run you between $8.00 - $10.00 at any retail or hardware store. This set has every bit for any project you could think of and the power to handle almost any material. It is definately worth the money. Works great on glass, metal, and stone.
I am very very satisfied.

Drilling Sea GlassOct 16, 2010
By Corkie Maus
These bits were purchased primarily for drilling sea glass for jewelry making. Since this was my first attempt at such a project, I didn't want to spend a lot of money experimenting.
I'm still trying these out, but so far, so good. I like having the variety to play with. I am using these with a Dremel and they work great. I have no complaints.
