Success!
I have done it, with only about 1/4 inch wear to the 1mm. disc too. I
was very careful to mark it out and to hold the angle grinder exactly
square to the cut and it only took about 15 minutes. I was amazed at
how successful it was. There was very little cleaning up required
also. I have only used these discs for cutting off rusted up nuts on
exhaust systems before and they always seemed to get damaged and worn
quickly.
It must have been due to the fact that I could see very well what I
was doing and kept the grinder from digging in and very true to the
cuts, that it was so easy.
Saved me at least 4 hours. Many thanks, I shall use this method
again.
Regards George.
