Ball-lock punches for heavy duty with point larger than shank P_-BKNB / P_-BKN_
The P_-BKN_ ball-lock punch for heavy 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 punch is able to withstand heavy loads thanks to the ball diameter 10/12mm. 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.
