Cutting Stainless Steel Angle ???

[wishiknew]

I need to cut some 4''x 4'' x 3/8'' stainless angle #304 like 80 times whats the best and fastest way to cut this stuff??? chopsaw ???

plasma torch?????

A good band saw will work perfect, with coolant. I cut it all the time. Don't let the blade feed be too slow or the SS will work harden.

Rule of thumb with stainless High feed, slow speed.

Send it to a saw house and pay the 50 bucks. You will save time and money in the long run.

Dewalt makes this chopsaw that has a carbide tipped blade it cuts anything clean and straight it will mow right through that angle works like a cold saw but with no mess. I have one and can cut anything with it from Shingles to hardened steel, wood, ceramic just about anything it the best saw I ever have seen for a shop looks like a chop saw or miter saw but the blade goes slow. I cut Inconel on mine all the time and it cuts like butter and its dead straight.

You buy one of these and it will replace all saws you have its everything in one saw and it cuts anything and I mean anything and you can hold a few thousandths tolerance cut to cut all day.

I have one of those and the carbide teeth take a shit after about 10 cuts of stainless. (after doing one set of exhaust pipes the thing was wasted (works fucking great on steel or chro-mo though) stainless is just too brutal for the speed they spin at. The best way to cut it is with a horizontal bandsaw, coolant, slow speed high feed like someone said. Or with a carbide low speed cold saw.

Thanks Guys Will be using a saw house Didnt know they had such a thing

Don't waste you money on one of those "Cuts All" carbide saws, a regular horizontal band saw with a bi-metal will cut it all day long with coolant.

Someone one here said the carbides took a shit after a few cuts, that's because of the thin cross section "exhaust tubing or headers" he was cutting, this is were the tooth pitch comes into play, if you use a blade with a large tooth spacing You will rip the teeth right off!

For the angle he wants to cut, if he used a 6-10S bi-metal blade he could cut that 304 SS 8 hrs a day for a week and have a blade that was still in good shape. For the headers and thin wall tube 4130, SS or mild steel a 10-14S bi-metal will do the same duty cycle.

I have people come to my shop asking how come they can't drill SS, they think they have to buy a cobalt, carbide, Tin coated or some exotic drill bit... nope a standard high speed steel, good quality drill bit, not from Home Depot will work all day long providing you do not work harden the material by letting the bit WEAR a hole though, you need the bit to be (1)sharp (2) slow speed on your drill press or hand drill (3) high feed pressure.

Because once you let that bit wear harden the SS because of not following the above, you will have one hell of a time getting through it.
