I need to mill down the t-bolts that came with the mounting kit from Enco to fit the table slots. I am just planing on putting them in my vise and using parallels to get them up and out of the way so I won’t hit the vise. Any advise on the speed settings and the cut depths? I’ve got six or so that I need to take some metal off of. The mill came with two that fit nicely. I have 3/8″ dia. 4 flute end mill cutter that should work OK.
