Tumble dryer vent hole

you could hire a core drill with a 110mm diamond core bit.

 

To many variables to realistically give a reply, what is the wall made of, distance etc etc.

 

As in earlier post, just hire core drill & 107m core bit.

Washing machine vent pipe is usually 100mm diameter, so a 105mm or maybe better a 107mm core drill will give a bit of wiggle room, also drill at a slight downward angle to the outside, that will allow any moisture to run out , rather than lie in the pipe.

 

Buy a condensing tumble drier. No hole needed and no hire of kit and making good needed. Sell old machine on Scumtree.

 

Strongly second BMC's reply, hole in the wall is daft unless you have free heating. Give old M/C away (freecycle.org?), nobody pays for that old stuff nowadays.
