Can I cut out a window in pre-sectional concrete garage

[youngalistai]

Not sure if I'm in the right section? But I want to enlarge and put a bigger window in a concrete Marley type garage can I cut it with any type of grinder?

Fair enough that slab he's cutting is particularly easy you could crack it in half with a club hammer I thought that sectional garages were particularly hard and if you give them a good hit with a club hammer nothing happens.

I'm pretty sure that garage sections are steel reinforced

A diamond blade should cut through easily enough,

I would probably use a 9" grinder though,

and a continuous rim blade rather than a segmented one for a cleaner cut and less chance of breakage.

[youngalistai]

Yeah thanks I thought it would be tough.

I've drilled similar.
Shatters easily.
You need a top drill and but SDS.

I'd avoid

Ok

Tell some bank robbers there are diamonds inside. They'll cut you a nice round window overnight (ref Hatton Garden)

Definitely.

Marley garages were steel reinforced but haven't been in production for around 35 years. Leofric took over Marley
and used C60 pre stressed panels .
It's possible to cut these with a 9 inch diamond disc.
You'll get more than dust coming off these when you cut them so goggles and gloves are a must..
