Anyone have a 8" or 10" hole saw?

[Patrolman]

I need to cut 4 large holes. Preferably 8" but could go up to a 10". Anyone have a hole saw I can borrow that is that large? Nobody in town seems to sell them.

I don't have one, sorry.

Any rental shops around? Could you use a sabre saw instead?

I thought about my pneumatic cutoff wheel, dremel, or sabre saw. I think they would all leave a pretty rough cut. This is in soft metal. I need to cut 4 holes to install our side-draft swamp cooler. It is silly that HD and Lowes sell the parts to install this, but not the tools.

Jig saw & a rope. Nail in the center, 4 to 5 inches of string and "CUT"

Big box stores seemed to have stopped carring the larger hole saws in favor of the adjustable style fly cutters. While most are made for cutting wood, I do believe I have seen some of them labeled for metal as well. Kinda like this: http://www.busybeetools.com/products/CIRCLE-CUTTER-WITH-FINE-ADJUSTMENT6-1%7B47%7D2IN..html

Bust out the SAWZALL Jeff!! :) If you get the right metal blade it will look as good as a hole saw, I do have decades experience using a Sawzall though.

I think I figured out what I am going to do. The metal is cheap, so it a mangle it, I will just buy another. Will post pics before, during, and after the process.

Are you only cutting metal or are you going thru wood too?

The metal is cheap, so it a mangle it, I will just buy another.If you get to chose your position while cutting, a Jigsaw with a metal cutting blade works very well.

When I do duct work I use the boot to trace my circle and cut with tin snips. Just use the smaller crimped end and cut just outside your line.
