I’m trying to figure out the best engraving settings for the piece I’m working on.
In my previous attempts, my 1/8 30 degree bits have broken when I get half way though the job (small font in picture) . They were ordered for me from McMasters, I do have some 30 degree spot drills on order from Drillman1.
Final depth .04, should I run multiple passes at say .01?
the pb with Vbits is that the tip has a surface speed of zero, so it basically rubs against the surface. I would think that reducing depth per pass is indeed a good move
