This is a style that is dimple-free and used for tubes or pipes. Mandrel punching offers the production of round or shaped holes in single or multiple-hole configurations in round, square, or rectangle tubing or pipe.

Mandrel style pierces a clean hole in one side of the tube. The mandrel supports the inner wall of the tube and where required a lower support is used under the mandrel.

This is a unique tool that pierces a burr-free bore.
