He thought me how to sharpen carbide sawblades , drill bits , endmills , wood cutters , knives .... And it all seemed so friggin easy when he demonstrated it
Back on topic :
This man told me never to use diamond wheels for carbon steel or hss .
Supposedly the carbon in the steel would do something to the diamond , wich is also carbon , and destroy it in no time .
I've always listened to his advice and use the diamond wheels exclusivly for carbide .
btw he also said never to breathe the carbide/diamond grinding dust .
Would be very dangerous . Don't know if it's true or not , but once again I carefully listened to his advice . Extraction unit ON , alway's !
