Create holes in metal, plastic, and fiberglass by using a wrench or driver to draw the punch onto the included stud. Drill pilot holes slightly larger than the size of the stud. These punches are also known as knockout and chassis punches.
Punches for hole diameters larger than 2" require an 11-ton hydraulic driver.
