I have tried a lot of different methods to cut copper windings off of stator and transformers and I still prefer a good sharp wood chisel to split small transformer winding, but for larger stator, armatures and transformers a diamond blade can't be beat.
Unlike those very thin cut off blades a diamond blade really lasts, even if you hit the steel.
I threw in a 1.75 inch armature into that one pic, just to show how well a diamond blade can stand up to torture. In the close up of my grinder is the same blade that I use to cut that stator and armature with along with a few dozen more and as you can see it has plenty of life left in it.
If you are wondering what that blade came out, it's from a cheap tile wet saw that I burned the motor out of pushing it to hard.
SORRY NO PICS! This forum has img turn off for new users :P
