@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!

@Sheetal - yes doing stuff yourself saves money and (as my father used to say) "If you want a job done well, do it yourself!"

But it pays to have the right tool for the job, it saves a lot of time  (and swearing) and in extreme cases you can't get the job done without it.

 Yes having drilling gun at home with different beads is quite helpful. You can do so much yourself. We have one from Black and Decker. Very satisfied. In India the regular way is to call a carpenter or electrician if you want to get any of these things done. Because labor is very cheap. But now they are either not available or they do poor job so better do it yourself. And after home depos coming in here, its so much fun to set things yourself.

@David  Sounds like a spade bit, but finer so it does not cut so deep.

It had a small drill bit centered inside a hollow cylinder with 4 teeth around the circumference, so like a hole saw it cut out a circle in the copper.  Depth was only enough to remove the copper plane and leave an isolated copper island with a hole in the middle for component leads.   Worked great in a Dremel.

Tried to find a link, no luck.  Used them 25 years ago so maybe they are not made anymore.  I think they were called 'drill mills', a google search turns up a lot of drill mills but nothing like this particular bit.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
