The EXACT™ conduit punches and dies are robust enough to punch holes in both mild and stainless steel. Engraved cross hairs on the dies deliver clearest alignment with pre-drawn cross hairs. Both the tooth geometry of the punches, and slug removal ports on the dies, provide optimal slug removal. Large size ID markings on both the punches and dies permit easy punch and die selection. EXACT™ punches and dies do not require spacers. Finally, notches on the punches allow for better grip during punch threading and de-threading. Altogether, EXACT™ punches and dies are another example of how Milwaukee's knockout system truly is the easiest way to punch!
