Trying to cut some rings out of sheet stainless steel (1.5mm thick).
Have mounted the sheet as shown (diameter is about 80mm)
I thought of using a cut-off tool, but the only one I have has a novel
carbide tip that produces a strange double groove (as seen in the
picture). The cutting oil I'm using produces a lot of smoke - should I
be drenching the thing in soluble oil instead?
