Pr3ssure Posted May 15, 2019 Share Posted May 15, 2019 So my uncle got this from my late grandfather's house. He thought it was stainless since it wasn't rusted bUT was with a bunch of rusted steel. He says it's extremely difficult to drill and when using a torch it throws a lot of metal. The holes in it were made with 7mm mag. He says it doesn't spark hardly at all from a grinder either. Any general ideas? If it helps my grandfather was a machinest and probably got this from work. Quote Link to comment Share on other sites More sharing options...
Daswulf Posted May 15, 2019 Share Posted May 15, 2019 Sure, it looks like it Could be stainless. What are your plans for it?. Looks like one of those awkward to use pieces. Stainless can be areal bear to drill. I got a bunch of stainless steel from my grandfathers estate. He built fire trucks among other things. Wasted a lot and still have some I'm saving for the right projects. Quote Link to comment Share on other sites More sharing options...

Daswulf Posted May 15, 2019 Share Posted May 15, 2019 It'll weld up but eat chepy brill bits if not very proper drilled. If welding without proper stuff expect it to rust around the weld. Quote Link to comment Share on other sites More sharing options...
Bustapepper Posted June 16, 2019 Share Posted June 16, 2019 To drill stainless in my opinion use cutting fluid for drilling. And go half the speed you normally would with a little extra pressure. Slow and steady is the way to go. Stainless is very gummy material. Very tough. Quote Link to comment Share on other sites More sharing options...
