I have a couple of "Rat files" that can make decent work of the ragged edges...

@ca94002...thanks for that.....I could easily have expanded this to two articles with all the other tools that commenters have given.  I have a leather punch and a hand reamer as you describe, so I should not have forgotten about them.  But then again, if I had covered everything I probably would not have got all these comments!

Good name -- it's akin to the tools used for trepanning, the technique of drilling a hole in people's skulls for treating various conditions.  Trepanning goes back to the Neolithic Era.

Mine are called pad cutters and are made by a company called Vector.

Here is the link

Find them at Mouser or Digikey

RE the drill bit in a tube, I have a few of these in different sizes. Mine are called pad cutters and are made by a company called Vector. These leave a center hole into which a press fit pin can be installed, the pin having a vertical slot into which leads and wires can be soldered. These are quite inexpensive when you consider the speed at which a breadboard can be constructed to build that one of a kind circuit for some project.

Hands on approaches

Great article - a reminder to the many approaches to making a "Hole in One" or more...

I have four, albeit less elegant, tools for making holes which are useful for some applications.1. LaboratoryHole Drill- originally used to put hole in lab stoppers - they come in a set stacked inside each other like Russian Dolls. For holes in soft materials like palstic - they work great. OK for the one up, low volume projects
2. The Leather Punch - mine has 5 or 6 dies for different size holes -originally belts etc but again thin sheets of rubber or plastic -works great...
3. Whitney Punches - a kit of various punches -  hand punch -quick and easy way to punch even through aluminum sheets...sort of a hand Greenlee
4. Tried and true - the Hand Reamer -for those slight adjustments to the - opps too small hole



All do not require charging before use or power cord!
