Help Identifying Type of Wood and How to Cut and Fix to it

[u0362565]

Hi all,

I'm new to diy and struggling to identify what this panel is made from, see attached images. I thought it was mdf? Has no grain pattern on surface but then the edge does have a grain so not so sure. It seems pretty hard and is about 7mm thick.

One of the images shows a scored rectangle. I'd like to cut this out and wondering what saw would be suitable? I have a pad saw but it's too hard for that.

I then want to screw a metal vent over the hole, bearing in mind it's 7mm thick and there will be a cavity behind how would you fix the vent? Some kind of toggle screw? I bought self drill plasterboard fixings but again I think it's too hard for those.

Thanks for the advice!

looks like mdf to me.
You can use a jigsaw to cut it, and screw it into position, or stick it with a grab adhesive

Oh good I got something right then! I was thinking today to maybe use a wood screw and bolt on the back as a screw alone would only be securing the vent through 7mm of mdf maybe that's plenty for a very light vent.

Thanks
