Packed well!
Great bits, used to probe PCB blanks and it works great for that. I did a little drilling with them and tolerance seems acurate, but be careful as they do break easily, use a really low plunge speed. They’re packed well unlike other bits so they won’t bump around and break during shipping.

Breaks super easy
I order about 200+ .3mm drill bits a year for use with .25mm fiber optics in models. While none of them are particularly robust, I normally get to drill about 40 holes or so on average with a single drill bit. With this set of 10, I only managed to get 23 total between all 10 drill bits - most broke during the first use. A complete waste of money.

Useful in model making
I use these for adding detail to my scale model cars. I’m currently working on the Deloren from back to the future and these will be used to create mounting locations for additional wiring.

Excellent drill
I use these to replace broken pivots in tiny clock gears. It’s necessary to make a .006” dia hole in the hardened steel arbor and the drill does it perfectly

Not quality drill
Just to look at them is to break them. Not sure they could be used on polystyrene.
