[TheForge] HELP---Drilling A-R Plate

[ries]

Pick one- Cheap, Exotic Materials, or Easy.

You cant have all three.

That stuff is nasty to machine. My guess is that the best way to go  
about it is to use solid carbide bits, in a big, very massive, slow  
industrial sized drill press- a radial drill would be best, with lots  
of coolant.
Second best would be a mag drill, with again, a solid carbide bit and  
lots of coolant.

Another option might be to burn em with a cutting torch, then grind em  
round with a grinding stone in a die grinder- but, of course, you  
would not get consistent exact round 1/4" holes.

Lots of times, you save money by buying the right thing in the first  
place- and me, I would be buying a piece of A36, if I was you.

there ?????
Does anybody hear me???????

I have some A-R ( Abrasive  Resistant)  Plate that I have tried to  
drill multiple holes in as part of a project I'm working on. I  need  
to use the AR plate because  I have it and I really can't afford to go  
out an purchase a piece of steel equal in size.  I looked on line and  
saw companies/ fabricators that offer to "drill  your AR  Plate for  
you..... How can I drill all the holes 20ea. (1/4") in this plate that  
I need without burning up the rest of my years  supply or my total  
budget for consumables for the rest of the year   in drill bits.     
Anybody know some tricks?????
