Do you need metric pin punches?

[toolaholic]

Hi all, I have SK and Mayhew fractional pin punches. Do I need metric? This Mayhew set is 3mm-8mm. And yes I know 8mm and 5/16 are the same. Mayhew Pro 62080 Metric Pin Punch Kit, 6-Piece https://www.amazon.com/dp/B002GKJ12K/?tag=atomicindus08-20

I guess it might depend on what you work on but, I've never owned metric punches but, that's just me and I've made it a long time without them.

 

[Moose-LandTran]

Do you work on metric stuff?

I have them, and need them, because everything here is metric so they're used frequently.

 

[PSYKO_Inc]

I've never needed them, just grab the next size down and it's always been close enough for me. I don't typically use them for precise jobs though , just driving out roll pins and such.

You must really be a "toolaholic" if you're asking about them.

I've never in my life even considered metric punches..

yeah I like being prepared!

our cars are Toyotas. The daughters' car is a Chevy lumina and the sole SAE hold out is the dodge Dakota R/T( only engine and transmission rest is metric)

Ive never encountered the need for metric pin punches, as long as your starting the pins with a starter punch, then moving to a pin punch you should be good. I would make sure I was covering standard length pin and long pattern pin in either sizing before I started attempting to acquire both.

 

[1950mercury]

For 36 bucks....yes you need them

 

[shockwave]

Punches no not really I have never used metric punches

lol, yeah it's almost like buying a "metric adjustable wrench". But I'd be inclined to buy metric punches if I needed some, as our cars are all metric.

This.

Most people don't realize this, but you are supposed to use a starter punch to get the pin moving. Then switch over to an appropriately sized punch. If you do that, then you won't need separate metric or standard pin punches.

 

[Adam.C]

Depends on the pin, right? If you are working with roll pins, it's good to have roll pin punches. Since the steel roll pin is pretty thin, you need to have the right sized punch. On AR rifles, those takedown pins should be metric. But they're not. Lots of otherwise metric stuff uses inch pins.

So if you worked on a range of products with roll pins, I'd get inch and metric roll pin punches.

For solid pins, it matters less - it's nice to have the right size since the hole supports the pin. Starter punches are pretty awesome. I ground cheap center punches and nail sets down in my youth.

Better get some metric hammers as well

 

[Ducatisoc]

Of course you need Metric.

Metric is the one true number system, all others be damned!


ALL HAIL OUR METRIC OVERLORD!

Haa haa haa good one!

You know they do actually exist, right? The rest of the world has the hammer weight in grams.

 

[four.cycle]

this is almost as silly as when the Dorman Products Company came out with metric cotter pins.
I still can't believe I was stupid enough to actually order them and put them into the inventory of nine stores. One of those "live and learn" experiences, I guess.

If it goes in the hole, it's a cotter pin.
Unless you're working on the Space Shuttle, I would imagine close enough would be close enough for a pin punch.

Whilst on the subject of hammers, why is it that most European hammers are of the cross peen variety whereas, most mechanics hammers in the U.S. are of the ball peen persuasion?

I don't actually know, i've wondered the same thing.

I do much prefer cross peen, as i find ball peen to be totally useless.

 

[joecon]

Because you can use a ball peen to make gaskets and you cant use a cross peen.
You can also use a ball peen to peen rivets it works better than a cross peen.

 

[Big Pete]

There's no shortage of ball pein hammers in Europe, or at least not in the UK, they average about a buck second hand for a 2 pounder.

 

[Rlfd213]

I keep my metric punches with my metric hammers and metric screwdrivers. I do have them separated left handed and right handed though.

You might not believe me, but I have metric screwdrivers, and I've seen lefty hammers, they aren't symmetric.

Oh. I don't make gaskets or peen rivets, so they're still no use to me. I actually use the cross peen quite a bit.

I should buy some more hammers..

I have metric punches, hammers and screwdrivers. I even have a metric adjustable at work.

 

[Ole Slewfoot]

My road service box has 2cross peins and one small BP.

But I have probably changed 300 Subaru CV's using a Yankee punch, so I might just be a bad example.

In a pinch, just buy a single 3mm pin punch, nothing else is really needed if you have good/quality units already. A

3mm - closest choices are 2.4ish and 3.2ish MM
4mm - 5/32 is 4.0mm, so a perfect fit
5mm - 3/16 is 4.8mm, undersize but strong enough
6mm - 7/32 is 5.5mm, again undersize but strong enough
8mm - no, 5/16 is 7.9X mm

Note that the inverse problem is similarly solved,

6 for 1/4
5 for 7/32
3/16 - required, as 5 is oversize and 4 is a size too small (=5/32)
4 for 5/32
3 for 1/8
2 for 3/32

 

[Jazz1]

One set of metric punches for each metric set of tools. I use them about as often as my metric drill bits

 

[pcmeiners]

If there is a need for metric punches perhaps there is a need for metric toilet paper?

 

[Know Wosad]

If you assemble difficult things that require one, making metric(or vice versa) slave pins might be needed.I keep some drill rod for the rare occasion.
I normally just use my eyeball when selecting punches. Same for drills 90% of the time uless a tap follows.

 

[themiller]

Til!

SAE pin punches stop at 1/16". If you work on small stuff your only choice is Metric. PB Swiss offers them down to 1mm.
