They chuck up nicely but be careful as they do break more easily than I thought (the smaller ones). I may have hit a hard spot but I lost the tip sharpness easier than expected on a couple of them. I usually buy cobalt or carbide so this may not be a good comparison. The hex shanks are very nice though.

Well made drill-bits. Unfortunately, non exchangeable, so prepare, if you brake the base, you can not replace it with other drill-bits to fit the hex head. I like them.

use the small diameter drills very very carefully, Impact driver adds vibration to the rotation of the drill causing the drill to snap and break, not suitable for tough materials e.g. metals,

I didn't have a chance yet to use the drill in hard conditions but my initial impression is very possitive
