Hardend steel, what cutter?

[DPG]

I've only just realised the title of the post is actually HARDEND STEEL. Now it may just be my juvenile mind, but that sounds like a ---- star's name to me. Daz

I've just drilled x2 50mm holes in a 2mm stainless enclosure this afternoon at home.

Took me like 10 mins with a cordless, starret cutter and some cutting paste.

Defiantly not structural,

Try's really slow but haven't try's with paste yet will give it a go, never seen anything like tbh, thought there may be a high end cutter out there , I've got 15 of them To do so I know even with paste and low spin speed I'm going to get through 4 or 5 bits

You can get cobalt cutters if you're really struggling.

I think you really need to do some investigating and find out why that plate is there before you turn it into Swiss cheese. It must have a purpose and I've got doubts it will still be performing it very well after you've whacked 15 downlight holes in it. Even the most basic risk assessment would dictate you need to find out why it's there.

I know why you are going through it, is the girder it is on is side.
I have never see a girder under the soft .
unless it is load bearing.

Starrett cutters will go through an inch of HT steel,with paste and the right speed. If the material is thick,four slots can be cut with a mini-grinder to aid clearing.
I would want to be knowing what i was perforating,before commencing.
