Actually, good drills but?

Negative,
Unfortunately wobbled the 2mm drill and 4 mm drill was honed to a cutting side around.
I suspect that triggered bending the packaging in Weichkunstoffblister and the big package.
See also customer photos and video.

Positive,
For the two defective drill I have received adequate compensation of 6 euros for sending in the pictures, the drills I did not return.

At least I can use the broken drill bit for drilling by hand in nest branches for the medullary canal nests my solitary bees.
