Hi, what's the best way to cut into the HVAC plenum in my home? I need
to add a 6"x6" takeoff. Sheetmetal snips would seem to butcher the cut
too much. I was wondering if a Rotozip tool would work well or
possible a Dremel tool?
how about a three bladed pair of snips.. two blades on the outside and
one in the middle, just cuts a thin metal strip out of the way without
much distortion on the base of the cut... and you have to know how to
hold the snips so you dont pull much on the surface metal.... any ace
hardware store will have them, harbor freight has them and probably
There are sheetmetal snips that are designed for this sort of cutting.
The head is at about a 75 degree angle to the handles so that you
can cut out of a flat surface. When my buddy with the snip collection
is not handy, I use a jigsaw (and earplugs).
