You know how when you try to drill into metal or hard surfaces and your drill bit "walks" no matter how much you think it's steady? Yeah, we have a tool for that. The Automatic Center Punch is one of those tools that if more people knew about, it would speed up many projects. Has a heavy-spring action, and you simply place the tip where you want to drill, and it punches a slight indentation in the surface. Just enough so that the drill bit won't walk. Works beautifully on wood and all hard surfaces.
