Precision Brand® TruPunch® Punch and Die Sets make perfect, custom washers, shims and gaskets in seconds. We achieve this by using our exclusive, patented punch, pilot, and pin system. No guess work is needed to center the I.D. and there is no need to scribe center lines. Material waste is reduced by creating a perfect shim every time. Every Punch and Die Set is packaged in a durable plastic case.
