Stainless Steel Automatic Center Punch
If you ever use a punch before you drill in any metal, you MUST GET ONE OF THESE! I have seen these
This is a replacement for the same model punch I bout a year or so ago. I have a fifty year old version of this. Works great. But during an airplane build, I seem to misplace items. A second one helps. And the bright color helps. (My other one is gun barrel blued). Trouble is, the new one broke after a couple hundred hours of my build. The striker is held in place by a cir-clip which failed. A penny part failure made the punch almost useless. The 50 year old model is still punching.
Failed to punch after about 20 punches. Apparently you have to keep polishing a component inside the punch. Very Inconvenient.
