It hold No. 80 bits like crazy!
After years of using a pin vise that would not accept a No. 80 drill, which is what I use most for the fine wires I use on my models, I decided to get this pin vise. Why did I wait? Of course, Tamiya makes a great product. It gripped onto the No. 80 drill bit as if it was forged in the vise.
I am extremely happy with this tool.
