Any suggestions on tooling for the drilling & tapping of 316 plate. Hole size range from 1/8" to 1/2". Parts being done on a CNC mill.
HSS, Cobalt or Carbide ? or any combination. If anyone is having success drilling & tapping this stuff I would appreciate any info they can supply, especially on the small diameters . . tool manufacture, speeds & feeds, etc.

Thank You, Sheldon
