The hardox will be used as blades for a metal guillotine.4mm thick will cut ok, get some decent discs or you will be changing then every 2 minutes.
4.5m is a loonnggg way though.
Depending how good the grinder is you might want to let it cool down (every 2 discs or something).
I can see that job taking an hour or more..
Plenty of quicker ways to do it but I guess if you had a plasma cutter you would be asking if you could cut hardox with it...
As long as you are not expecting the weld area to have the same properties as the hardox then it arc welds just fine with normal rods.
May be better choices, what's the application?
Why not just bolt the blades on?The hardox will be used as blades for a metal guillotine.
I'm not sure how I'm going to drill the holes in them. This is all a first for me, as you can obviously tell. I have some jobber drill bits, but surely they wouldn't get through hardox?Why not just bolt the blades on?
Then you can remove them for sharpening or replace them if damaged/worn out
If you cant drill it, you can make suitable clamping set up to hold blade in place against a back stop. But with the right drill almost everything is drillable.I'm not sure how I'm going to drill the holes in them. This is all a first for me, as you can obviously tell.

Could you use a carbide drill bit in a normal drill or do you need a mag drill or some other specialist drill?If yo

You can't use carbide in a hand drill, its not rigid enough and it will chip/break.Could you use a carbide drill bit in a normal drill or do you need a mag drill or some other specialist drill?
Thanks. This is all starting to sound expensive. I think I'll have to find an alternative to drilling the hardox.You can't use carbide in a hand drill, its not rigid enough and it will chip/break.
Probably can use it in a mag drill.
You can buy hardox specific cutters for magdrills.
What does the manuf's say about cutting, drilling, and welding ?Could you use a carbide drill bit in a normal drill or do you need a mag drill or some other specialist drill?

Just check that is the right material for the job.The hardox will be used as blades for a metal guillotine.
Well, unfortunately, I just bought 36 quids worth of hardox 450 before you posted this. So, I'm going to give making a blade of it a go and see if it holds up OK. If not, it was a 36 pound lesson learned.Just check that is the right material for the job.
Conflicting info on the internet as to whether it can or can’t take, and retain, a ‘sharp’ edge. Hardox is a tough, wear resistant material which means it is used for things like digger bucket cutting edges, wear bars, crusher parts etc. In a lot of years of metal bashing I’ve yet to see Hardox used for the application you are intending
