Every GEARWRENCH Starter punch has the strength that professionals expect from our name. These punches are ideal for starting or installing pins or rivets, and theyre built to meet or exceed ASME specifications for proven strength. The punches feature a precision-hardened work tip for punching metal, but a softened and tapered striking surface on the back that reduces chipping. Identify your punches at a glance with the ground surface finish and laser-etched size identification marks.
