What of it? That's known as variable pitch. Some are variable pitch, some are constant pitch. That has nothing to do with whether they are suitable for metal or not. Most all-purpose hole saws are variable pitch, like the red one; for example - link.

No, they are not. The teeth are actually larger relative to the body of the hole saw than in the first picture of the red hole saw.

Again, what of it? Your claim that the pictured red hole saw is not for metal because it needs much finer teeth for metal is plain wrong.

Malenko:

settle down ladies, not every fight is worth having.

I did mine with a drill bit and a hole punch. cake walk.

whammoed:

I prefer punches, but bi-metal hole saws work dandy.  You can find bi-metal hole saws at any hardware store.  They don't leave as clean of a hole, but the button covers it all up anyway.  Look on ebay for greenlee punches if you want to go that route, used ones can be had cheaply if you are patient.
If you are local to me, you can borrow a punch...don't see a location in your profile.

DaOld Man:

You have to be careful with those hole punches that are pictured (commonly known in the trade as Knockout Punches.)
They cut a hole bigger than they are marked for, because they cut holes for conduit and fittings to install in.
Conduit measurements are marked inside diameter. Knock out punches are marked inside diameter also, but they actually cut outside diameter. Plus good ones are rather expensive, so i just thought id throw that in so if anyone plans to go out and buy one they will know.


GameTech:

OK thanks for info guys... Yeah, I'm having a hard time finding something to cut such a "large" hole in this metal control panel without marking up the brand new overlay thats on it.  I will check for punches, and more..

Oh, I'm in the Seattle/Olympia area of Washington State.
