When the walls are made of cardboard, you do panick a bit

Get a heat mat and have a spray bottle of water handy!

Thanks, it’s not as bad as I thought it would be to do. It’s the 140mm hole and 90mm hole for the shower I’m not looking forward to doing

@Pro Tiler Tools can probably help with that problem!

You need a reaming bit, (finger bit) mark out the hole and either use the biggest bit you can find
120-125mm then use the reaming bit to enlarge it.
Something like this.

Vacuum Brazed Finger Bits M14 - ATS Diamond Tools - https://www.atsdiamondtools.co.uk/product/vacuum-brazed-finger-bits-m14/

Or just use the biggest you have and stitch drill and grind rest away.

The only one that @Pro Tiler Tools have is the Montolit to my knowledge and it’s very expensive and aggressive, and if this is your one and only time you’ll use it then the Montolit is an expensive bit.

Used a grinder instead, wasnt fun

Good job! First attempt?

 

[Jonathanb]

Yep first attempt. Just took my time. The 90mm hole was a lot more difficult to do with the grinder.
