Interesting. I haven't seen 2-piece punches like that. They remind me of clicker dies.
The biggest trouble I have with using these is selecting the best backer. Something that gives sufficient support, but also allows the punch to enter and finish the cut. I've tried scrap cutting boards (they're too hard) and scraps of plywood (the grain gives me issues). I think that an end grain board would be best, but haven't tried it yet.
What do you use?

OP
I actually use a piece of scrap from an end grain cutting board that I made a couple of years ago. It works PERFECT. Once you have the punches sharp, you just tap the thing with a rubber mallet and most gasket material (the stuff I mostly cut anyhow) sheers clean as can be.
Damn those gonna make some big holes.

It's for the jolly green giant's belt buckle.
OP
The smallest is perfect for #10 machine screws... which is was I needed... and there's another that fits the backside of a 1526/7 light socket as well...
I have a lot of hole punches but when I need a size I don't have I make one out of a piece of pipe or tubing. I have a lathe I can use but I've also just ground the edge on a bench grinder and finished on a belt grinder with a fine grit belt.
One of the common uses I've had was to cut long cyndrical holes in foam to pack things like small camera lenses etc for shipping. I recently sold an archery set on ebay and packed the 3 arrows by finding a 3" cardboard tube and cutting some round 3" slugs of foam with one. You just have to twist the punches through by hand. I then cut a 1/2" hole in the center and inserted the arrows. This kept the fletching suspended inside the cardboard tube. I then add the new hole punch to the punch drawer.
I also like using an end grain on a board for the backing when cutting gasket paper etc.
I've collected quite a few over the years but you often don't have that exact size you're looking for.
I've found it's quite easy to grind an edge on a piece of tubing or scrap pipe that's good enough to get the job done.

When using smaller ones I find that chucking it up in the cordless drill and rotating it makes a clean cut easier than hammering it through your material. It’s also a good way to sharpen up the die cutter. Get some 220 or 360 wet or dry sandpaper and some cutting oil. Start rotating with the drill and you get an even sharp edge all around.

I use the drill press. But just as a press. I don't bother to turn it on.
I recently made a replacement leather sweatband for a hat, and since it was my summer hat, I perforated it. I bought a 6 hole punch on eBay, and punched the hundreds of holes using the drill press in maybe half an hour.

Laboratory cork borers are another option for all kinds of projects putting holes in soft materials. For things like gaskets, they're perfect.
I'll often use scrap MDF or an old plastic cutting board as a backer, but end grain wood is probably the best.

I use Osborne arch punches for grommets in canvas work and their rotary punch for screw holes in gaskets. Expensive but almost mandatory for production work (I used to have a marine canvas shop but still use them for DIY). They will easily cut though 8 layers of 9oz cloth. I use wood as a backer.
I tried an HF punch (in a set) for a size I didn't already have and they were useless on 1/8" thick felt for 44 cal black powder wads. I think the HF would be ok for a one time project on a couple of engine gaskets...maybe.

Have had good longevity and useage with the Mayhew hollow punch set. Nice because you can add/use 2 punches at a time. Also, larger individual punch are available if needed.

So it can punch concentric circles?

About 30 years ago, I bought an English MAUN wad punch #1001-05 hollow punch kit. For larger circle cuts I have an ECLIPSE razor sharp cutter. While I do not use these items too often, when I need them, they make the job easier and more accurate.
I like tools, so I may look into buying the punch sets shown.

I use a nylon kitchen cutting board. This works perfectly, every time.

I bought 2 different sets from the neighborhood Tandy leather company store back in the late 70's. one set is 3 fixed size. the other set has a driver and detachable different size cutters maybe up to 9mm. I from time to time make my own gaskets and these are indispensable in that process.

Always use the end of a piece of wood. Parallel with the grain.
Thats how i was taught abyways.

As Bob15 stated in his reply the punches screw together and make perfect washer shapes in any gasket material. The Mayhew set is expensive but you get your money's worth. These punches are sharp right out out the box and have worked very well for me.

I've owned this Boehm set for many years now and used in conjunction with my trusty "Thor" mallet it has proven its worth, time and time again. From making washers to working with leather, plastics, canvas etc it never fails to please. I remember it being expensive to purchase at the time, but the price is long forgotten now; many the plumbing jobs etc I've been able to solve thanks to it!

Looks very similar to the Facom sets.....you can buy individual sizes (from 3-50mm) if you need them.

I used a similar set for all my handle bumpers on my vises! Great stuff!
Have had those imported cheapies for many years and they are OK, use the end of a hardwood 4 X 4 in the vise for back up. Just made some scratch pads from twenty envelopes stapled together and the 1/2" punched right through effortlessly.

They go on sale for less than $10.
