The MulWark 5” Automatic Center Punch has a built-in spring tension mechanism that automatically strikes a sharp blow when downward pressure is applied, without the use of a hammer, leaving one hand free to steady the work. The all-steel punch is adjustable as to the amount of force per blow to control the depth and size of the mark. This tool is ideal for punching, marking, scribing, and staking most metals and woods to start drill, nail or screw holes. Made of hardened tempered steel and featured with ergonomical design, it’s heavy-duty yet easy to use, makes the most economic choice for machinists, automotive repair pros, hobbyists and do-it-yourselfers. You may use it for precise drilling applications, glass breaking in rescue work, and as a letter stamp set, an awl for belt or a pin press
