  • The cutting parameters shown in the table are merely a starting guideline
  • The coolant supply is critical for the provision of stable machining condi-
for general machining. Values should be varied depending on the power ortions and enhanced tool life. A large coolant volume should be supplied,
rigidity of the machine to be used. Optimum conditions should be selectedespecially when drilling diffi cult-to-cut materials.
depending on the actual chip control or damage on edges.• When drilling stainless steel with low machinability such as austenitic
  • When using the smaller diameter tools in each range, set the feed “f” to stainless steel with a depth deeper than L/D = 3, a pecking cycle or interthe lower recommended values. nal coolant supply is recommended.
