Ball-lock punches for light duty with point larger than shank P_-BJNB / P_-BJN_
The P_-BJN_ ball-lock punch for light duty with point larger than shank is fastened with a ball in the tool for quick removal. The wide end means that the body can be lower than the diameter of the working part. The ball-lock punches are mounted in a tool to cut, bend or form sheet. We are machining our punches following your needs or drawing. They are also available as blank.
