  • Because the cutting conditions may be changed depending on the material type, hardness, machinability, machine tool, and coolant, the most appropriate conditions must be decided whilst referring the chip control condition and tool failure mode.
  • When using the smaller diameter tools in each range, set the feed “f” to the lower recommended values.
  • When drilling diffi cult-to-cut materials, coolant supplying conditions are critical for successful drilling. So, the use of constant and fl ood coolant is highly recommended.
  • When the work material is kind of austenitic stainless steel (e.g. X5CrNi18-9) and the hole depth is over L/D = 2, using step drilling program or using DSX drill with oil hole is recommended.
