I have another question about grinding HSS toolbits, what is the importance of grinding the top relief? I don't grind the top relief and the bits seem to cut fine and leave a decent finish. The reason for not grinding the top relief is that I don't do it worth a flip and usually end up starting all over so I just quit doing it and things seem okay. I know I am missing something here.
