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.

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.

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.

These work fantastic for wine bottle crafts and what not - so great that I bought two. They last a long time before they start dulling...and then you can find another purpose for them.

I used the bit you see on the far right in the set to do a port job on a Traxxas T-Maxx 3.3 engine.
The bit cut the brass like it was plastic or ice!
The crankshaft (second from left) is steel and took a little work and cool down cycles as it got quite warm to the touch.
The bit still looks like it did new after a few minutes grinding steel.
Good value, nice finish and fine for crafts though maybe not a commercial grade I think they will last me a long, long time.

Been using this for my rotary tool and they've been great! Make sure to cool off the bits in water every once in a while during long use and they'll last a lifetime(or at least a long time).

Great little bits. I use them mainly for drilling my stones that I use to make pendant jewelry. The key to long life of any bit like these is is to keep them cool by applying water and taking your time.Pro-Quality 20-Piece Diamond-Point Bit Set for Rotary Tool - Glass, Stone, Ceramic

I only used two of the bits so far. They worked wonderfully. I was able to use them in my Dremel just fine.

By M. Hunt

Great item! I use them for carving and shaping semiprecious gemstones and it works very well in my Dremel. I thought this product was too good to be true and found quite the opposite! Didn't want to spend a ton on diamond bits so this was a happy find.

These are pretty fun to use with the Dremel engraver. I've got the full size dremel tool, but it's much heavier and awkward to use, so I use the smaller one. The burs are easy to insert into the tool and make working with wood much more fun. They allow me to give my pieces a touch of flair without taking forever. There are many sizes and shapes, so the selection is pretty good. Definitely recommend
