Inspecting some HBM ER25 Collets and a look at some bue nano inserts

To celebrate my 3 year channel birthday I bought myself a set of ER25 collets from Dutch reseller HBM. In this video I try to find out if they are good enough to keep, for when I start machining my own collet chuck for on my vintage Karger lathe. Oh, and I also start testing some blue nano ccmt inserts in this video.

FYI: I am trying to make a little money for my youtube hobby through the Banggood affiliates program. Follow the link below, buy something you NEED and I'll earn some commission. Doesn’t cost you anything extra. You're basically taking money out of Banggood's pockets and putting it in mine :)
