I first tried using these in a hand drill and that worked fine for a PC Board but when I had to make a deeper hole in wood, the slightest tilt broke the 1 mm drill bit off and clogged the hole and I had no way of getting it out as it was nearly the full length. I got 3 good holes from it before I got off axis while it was in the wood and the hardness of these make them very unforgiving, they do not flex at all, only break off.Very sharp and cut fast, excellent for electronics or mounting small hardware . I've bought a few sets of them so far and am very pleased!

All of them are finely crafted. Nice straight shafts and sharp drills. There are times when you need a pin drill, like working on carburetor fuel metering passages, and this is the kit that will allow you do drill those tiny holes. A very good value.

Sind bei mir sofort abgebrochen, obwohl ich sehr vorsichtig und gerade mit einem Akku- Handgerät in ein Holzei gebohrt habe…So habe ich einen Bohrer nach dem anderen verschlissen.Wenn sie nicht abgebrochen sind, haben sie gute Löcher gebohrt.Vielleicht geht es mit einer Ständerbohrmaschine besser, bei der man sehr gerade in ein sehr gut fixiertes Werkstück bohrt…

Und auch wenn das vielleicht aufgrund der geringen Dicke zu erwarten war hätte ich mir bei bisher drei Versuchen doch wenigstens ein Loch und nicht drei abgebrochene Bohrer gewünscht.
