We needed these for a small ceramic Christmas project, and they did the job well. At only $2.00 a bit, the price was more than worth it. Also like the plastic case they came in to protect them while not in use. Recommend.

They last about 10 holes, but when they get hot, the wax in them, that is supposed to keep them cool, 🙄 gets thrown out of the bit all over the wall....

First off I was not too sure about them after reading some reviews. Came packaged in a sturdy case. I used them for a free standing circular rock sculpture using 2"-4" river rock. Using a drill press on 3/4 speed and a 3" container with enough water and a thin piece of wood on the bottom I was able to drill through 20-30 rocks like a knife going through soft butter with 1 of them. Needless to say these bits work great. Save the used ones and reuse them to use as a grinder. Highly recommend.

I bought these to put drain holes in ceramic pots that I find at thrift stores. They are working wonderfully and nary a pot has had to be discarded due to being broken during the drilling!

I purchased a drill set with high expectations, but unfortunately, my experience fell short. The drills in the set didn't live up to the durability I anticipated; they seemed to wear out much faster than I would have liked. As someone who frequently tackles DIY projects, having tools that stand the test of time is crucial. I hope future improvements can be made to enhance the longevity of these drills.
