I need to bore a 4" hole through a double brick wall, on the inside is a stainless steel plate. The stainless is just a cladding, so not very thick.
What tool can I use to cut through the stainless steel plate cladding?
Any help would be appreciated
Thx
a normal starett cutter will do this but keep the speed low a it will burn and blunt very quickly
or even a diamond cutter as you would use normally for holes -these will cut steel reinforce rods in concrete -again take it slowly
cheers

hi abe,
heat does not travel well in SS, ie it a good insulator. as richard said, use a starett holesaw 4" very low speed as speed on these things is measured at meter per second.
you need to turn such diameter at 30 to 40 rpm. use cutting coolant or the holesaw will burn. if getting hot, stop and cool and so on till you go through.
watch out, the edge is very sharp. file it before you stick your hand through.
good luck.

hi guys ,agree with your answers use plenty of cutting fluid or maybe some tallo..............and cool with water.
rbartlett and chemi-cool <- sounds like good advise to me, cut a few holes through shipping containers lined with stainless in my short time in the field so far and thats exactly how i tackled the situation, cant go wrong Aiyub ;)
Thank you everyone with all your help.
Tackling job tomorrow
Any cobalt hole saw w/ plenty of water and/or cutting oil. Do it on awwekly basis.
You can use a Smith & Arrow cutting disc. I use it for my line of work. I think it will do just fine with your stainless steel plate.

If all else fails with SS borrow a plasma cutter, quick and easy.

Various cutting oils actually make it worse. Someone commented the original post was old but various members could still benefit from other members' knowledge being added.
