A blanking punch which extends from a first portion to a second portion along a blanking direction is provided. The second portion has a cutting edge. An engaging portion is provided/designed between the first portion and the second portion. The engaging portion enables the blanking punch to be removed from a workpiece counter to the blanking direction.

A punch system for producing pilot holes through standing seam type roofing includes a punch having a striking end and a tip portion; and a punch guide that directs and controls action of the punch. The punch guide has an alignment member sized and shaped to conform to a raised rib portion of the standing seam type roofing; a tubular member affixed to the alignment member; and a force controlling mechanism contained within the tubular member and further including a punch centering sleeve, a plurality of spacers and a spring. The spacers set a stroke length for punch and sharpening of the punch is accommodated by rearrangement of the spacers.

A method and a set-up apparatus for a tool for punching or forming sheet-form materials having a punch holder into which a punch of the tool is insertable and a die holder into which a die of the tool or a die carrier holding the die is insertable. The punch holder and the die holder are movable towards one another by a guide. The punch holder is transferred along the guide into a measuring position in which the punch rests on a surface of a measurement object which rests on the die. A distance of the punch holder is measured from a zero point of the die holder and a distance of the measurement object from the zero point. An evaluation device outputs a punch length of the punch and a die height of the die or a die height of the die arranged in the die carrier.

Embodiments of the invention provide a die retainer for use in a tool. The die retainer can include a ram head, a release button, and a die pin. The ram head includes a die cavity and a pair of lateral sides on opposing sides of the die cavity. The release button can extend through a release button hole formed in the ram head hand include opposing ends that extend past each of the corresponding pair of lateral sides. The die pin extends through a die pin cavity that intersects the release button hole. The die release button can be actuatable from either of the opposing ends to retract the die pin from the die cavity.
