Good enough for the price

I make my own tools. Sometimes I need to drill precise submillimeter holes. These work quite nicely. Make sure to use with a drill press. Drilling by hand isn't advised.

Good value I think

Best deal overall so far. I am a novice Horologist and silversmith so I break alot of tiny drill bits. These seem like mid range quality bits. I've broken some and some I expected to break and didn't. Point being these are very small but there are enough here to get through a project if some do happen to break. I will buy again.

work will for the price

The drills are sharp and cut well at a good price the only down side is they did not come in a nice case as shown but in 3 packs of 10 with each pack holding the 10 different sizes. The box shown would have been nicer to have they should show what you are going to get.
