Punches use their tip to mark, pierce, or position parts and materials. Also known as hand punches, they are used in a range of metalworking, manufacturing, automotive, and construction applications. Pin loosening and removing punches dislodge and pull out pins, rivets, bushings, and other parts. Hole aligning punches slide through holes in stacked parts or layers of material to align the holes for inserting a fastener. Centering and marking punches make an indentation that marks the spot to drill a hole in a workpiece. Hole making punches puncture material with their sharp cutting edge to create a hole.
