Need tips on drilling holes in stainless steel saw blade for my rear tine tiller converted to wire trencher.
Basically I have a 14" fire and rescue blade that needs 4, 3/8" holes for the hub/collar to mount up (I'll get pics up later).
Anyway I'd tried this years ago with regular drill bits and it was a joke.
I know I need low rpms and some oil. What I don't know is exactly what kind of bit is best????titanium, carbide etc.
Please help any recommendations appreciated.
