Best way to cut a hole in aluminum siding.

Use a nibbler to cut in a straight line. A nibbler is made from two small blades that vibrate up and down at a very high speed. Cut a piece of aluminum about 1 inch bigger than the hole using tin snips. When using a hole saw to drill the hole in aluminum siding keep the saw slightly tilted to one side to reduce the chances that the hole saw will bind while cutting the hole.

For these kinds of cuts tin snips are very handy. If you notice that the saw binds pull the hole saw away from the siding tilt the hole saw in a different direction and restart drilling the hole. Hopefully you have a set of tin snips that will allow you to make cuts in any direction. Take the x acto knife and cut out the portion of the aluminum siding that contains the large hole.

Cut a portion of the intact siding material to match the piece you just cut out. The less you have to cut the better. The speed along with the vibrating blades ensure that you get a straight cut. There will come a time in any aluminum siding project where you ll need to make a cut that isn t as simple as a straight vertical cut you can make with your saw.
