Need to cut exhaust hole in garage door - tool to use/not to use?

[Mike vonBuelow]

Hi metal heads...

Due to my laser engraving 'office' being in the garage, I'm needing an 3.25" exhaust vent hole in my garage door for a vent.

Needing advice on how to...

Should I call someone? In the OKC area if it matters.

Just go to one of the big-box stores and get a hole saw. They will cut though almost anything. I cut a 6" hole through the wall of my steel building for my exhaust, no problem.

Mike,

I would purchase a dryer vent and install it in the door so the hole has a finished look and you will have the necessary connection for the hose on the inside that you can connect and remove the hose as required. Most metal doors are pretty thin so you should be able to cut the hole with just about any tool you prefer but be careful using a hole saw as they can be pretty aggressive in thin sheet.

Right Keith, I did purchase a metal 'port' to fit around the hole.

I may live in Oklahoma, but I'm not hick
