How can I recover a "crystallized" cutting disk? Answered
I was cutting an iron L rod, and the cutting disk began to produce red sparks, instead of these habitual bright orange. Simultaneously, its cutting effectiveness was down dramatically. I searched in the web, and learned that this phenomen is named crystallization,and it is due to overheating. Now, my disk is a new one, I want not throw it to the waste.
Any idea how to get it back? THANKS IN ADVANCE!
