Holes without hole saw?

Hello all, trying to set up a grow cab with a 4" exhaust and a passive intake, what's the best way to go about doing this. I'm working with some shitty particle board

You can drill a 1/2" hole near the circle drawn and insert a jig saw and cut it out that way. A 4" hole saw is a bit expensive if you only need it every now and then.

lol i woulda hadta buy a 6in hole saw for 40 bucks if it wasnt for a jig saw. goodtimez

key hole saw will cost ya like $3 and is another choice

Also they make little wire saws that would work with your "shitty particle board" that way you can like slip the wire through then cut a circle. Probably the cheapest route. Looks like a little piano wire with serrated teeth.

Have you ever used a keyhole saw to cut 1/2 or thicker particle board? I'm willing to say that no, you haven't, or you wouldn't be suggesting it.

ok, you did not get this from me.

in the pinchy times when I needed one tool I only needed for one job (rare, still dishonest, I know) I would buy it, use it, and return it.
Just to get the job done.

I'll delete this self incriminating bit of advice after a reply,,,,

home depot is stupid they dont check anything. try harbor freight ten peice hole cutting kit up to 6 inch holes. if u got a drill. this is a good investment for ten dollars. cheap. love harbor freight.

i bought 2 cfl's from home depot, and returned 2 dead cfl's for cash back plus tax!
