I became the proud owner of a set of diamond drill bits years ago.
Many "friends" have tried to borrow them...but to no avail!...LOL
I use them in cases like this...with lube and gentle pressures...they cut through just about anything...and by stepping up in size...I can get an easyout to fit.
Perhaps an investment of a few dollars would set you up too.
