Review on AI Vise Piece Size 4 8Mm by Tim Rushing

These are heavy duty and 2 out of 4 vises work but the collet of the other 2 vises are not drilled properly. When you insert the pin into the largest vise, the pin is at a significant angle to the handle. I thought it was just a bad set and went back to buy another set and had the exact same issue. This set is cheap and you get what you pay for.
