Cutting Intercooler Or Exhaust Pipe

[zebra]

Never tried tungsten on stainless

I'm using Milwaukee ones at the moment and they are unreal for going through alloy but any bi-metal ones would be fine don't even try to go through stainless with them

No offense. But you are doing it wrong if you cant do stainless sheet with a bi metal hole saw

It really depends on the grade and quality of stainless, and how good the holesaw is. It's a good way to damage your arm if it isn't in a drill press, as the kick on a holesaw when it grabs with a hand drill is harsh.

I have new drill bits here that just polish the stainless, due to the stainless being harder than the drill bit. Cobalt drill sets are definitely worth the coin.

Tired it a few times on a couple heat shields I made for vls with the gate welded on top of the manifold and doing one cut with the bi-metal hole saw killed it yeah I got through but destroyed a $80 holesaw in the process much easier doing it with the hydraulic punch if your cutting through sheet less then a mm yeah go ahead but 2mm plus your just throughing your money away

Much slower speeds also required for stainless or you WILL kill the drill bit so damn quickly.

But I'm with Scotty, cobalt all the way!

We were in a pinch once and use a builders wood saw to cut some alloy intercooler pipe. worked so well we have done it again. Cuts fast and straight, much straighter than a hack saw anyway haha

If you use a bit of wd40 or light machine oil as lube, a carbide tipped blade on a timber cutting drop saw works perfectly.
