A New Tool

This the Micro-Punch set from Micro-Mark. 9 punches, ranging from 1 mm to 5 mm in 0.5 mm increments.

The copper strip is 26 gauge and was annealed prior to punching out some small discs.  Also, the punch was lubricated with Bur-Life.  Although the punches are advertised as hardened, I take no chances and anneal and lubricate.  I will say this, although small in size, the tool is precisely made.  I doubt if I will ever use the tinier punches, but the four larger ones have potential.

I keep the set in an Altoids mint tin. It does not come in any kind of storage container other than a rather weak plastic bag.


  1. I swear, how cool is it that we get to make cool stuff, and use cool tools?

  2. Thanks, John. Yes, it is a cool little tool. You probably could make one your self, that is, if you have the need, with the precision tools you have.
