  • Not recommended

Notes: When the drilling depth is deeper than L/D = 5, use drill pecking every 10 to 50% of the drill diameter.

  • The above cutting conditions are applied to when a water soluble cutting fluid is used. For drilling a hole smaller than ø0.3 mm, use of a starting drill is recommended.
  • When setting the drill, the drill run out should be within 0.002 mm on the taper. (Especially for the drill diameter smaller than ø0.5 mm)

Notes: For hard materials and stainless steels which have work-hardening nature, DSM-CP140 is recommended.

  • Above cutting conditions are of using a water-soluble cutting fluid. When using a water-insoluble type, set the cutting speed to lower side.
