18 x 10 Rectangle Hole Cut In Square Duct
Hello I’m new here and this is my first post. I am a hvac installer. I am wanting to see what the easiest way is to cut a 18 x 10 inch hole in square duct with the rectangle being 2 inches off the top and 1 inch off the side even on top and sides.

Welcome aboard!
I have found the easiest way to get a hole in a duct is to tell someone else to do it! lol Now, the serious part. Is it already hanging? Do you have electric snips? Do you have an apprentice, wait, we already went over that…
If thinking was easy,
everyone would do it!Regarding Russian Roulette; five out of six players think it is a safe, enjoyable game!

Electric shears are for sissys.

I’m tired of these mediocre “semi flammable” refrigerants. If we’re going to do it let’s do it right.
Unless we change direction we are likely to end up where we are going.

Best thing since slice π
Malco has shears that go on an impactSent from my iPhone using Tapatalk
That’s the one the guy I worked for uses.
I just consider it exercising my grip and I use hand shears.

~~~~~~~~~~~~~~I don’t know when I compare my cuts with his mine are better although I’m sure there’s a lot of different shoes out there and maybe some do better than the one he uses. Although I think the biggest thing is that often it’s not really the right direction whereas with shears I can have several pairs and always have the right direction for whatever cut I’m making.

Oh and doesn’t everybody use a duct hammer and a flat blade screwdriver to start the hole? A step bit is cheating.

Shears can go left / right / straight no problem.
