Cutting a hole in a steeltech shed

James Bond Junior

I have a steeltech shed internally lined with slabs of insulation board. I want to cut a hole in the wall of the shed in order to allow a vent for a clothes dryer within rather than hanging the vent out the window.

What would be my best way to do this?

Mine is almost identical save for the insulation as this one.

Drill a few holes then use a jigsaw or reciprocating saw to cut the hole.

Put a metal cutting blade on also.....

Q of course, he is the man to see.

These hole saws are in Lidl at the moment. Not sure if they're big enough but worth a look as they would do a very clean job.

I was googling something similar. I'll have a peep later, thanks. Handy set to have but I've bought lidl bits before and they tend to be shoite enough.

Doubt they would be big enough.

get a proper hole saw. its the only neat way to cut a circle in box profile cladding. you will be left with a nice clean hole that you can silicone around easily instead of a hocked out mess. i have made that mistake before

What size would I be looking to get? What diameter for instance?

Have you bought the dryer? If not buy a condenser dryer and then you won't need to cut the shed.

depends on the piping. either 100mm or 115mm.
better off getting the cover for the outside first and getting a hole saw to match the flange for the flexi pipe

what part of the country are you in. it could be cheaper to get someone to cutt it for you rather than buy one

Dryer is in place and the vent goes out the window but I am not mad about the idea of leaving the window open for two reasons, wet weather when the dryer is in use means rain gets in a soaks the inside and I keep a lot of tools in said shed and would be afraid the could be stolen if the window is open a lot.

I am in Limerick. I have a builder in doing other jobs at the moment who could do it but I feel this is something I could tackle myself.

not hard to do. not sure where to get cheapish holesaws in limerick. mckeenas sell starret but thats overkill for 1 hole


get a decent drill with a side handle if possible and go slow. let the hole saw spin and slowly move forward. if your too agresssive it will catch and kick you

I would remove the insulation inside where you want to cut the hole and then fix a piece of timber on the side, fixed with screws from the outside, with the score holes inside the area where the circle will be cut.
The purpose of this piece of timber is to hold the bit firm so as the cutter will not jump all over the place, especially if you are not used to this: a 5" or 6" diameter hole saw will, as noted above, have some kick if it sticks, so make sure you don't have your thumb wrapped around the handle of the drill, you might break your wrist/thumb, or be pitched off a ladder if you are up on one.

Sheet metal nibbler or nibbler attachment for a drill. 4inch Holesaw will be a nightmare if corrugations are in wrong place.

get about 20-30cm of 4" waste pipe and use that to gauge the size of the hole. If you have a builder there he might have some in the back of the van. Then bond / seal this in place after you've cut the hole in the shed. The flexi duct from the dryer can be pulled into the center of the 4" pipe.

Wouldn't it be easier to cut it square with a saw and then use a square to round duct adapter?
