Edit
SOme of you may wonder about the centering sleeve feature, if it will be a pain and in the way. Just slide a small spring off the punch and in 10 seconds that feature is negated, and it is a regular center punch. But the nice thing: when you want to use it to find the center of an overlaying predrilled hole, like a hinge, just take ten seconds and replace that spring!
Like I said above this tool is new in the box. A well made auto center punch.
