SG-ESR/ESS Drills Longest service life for high-speed steel (HSS) drills
  • Powder HSS with SG Coating and the tool life is 2-3 times of conventional drills.
Stable and high precision drilling
  • Extremely precise positioning and Stable drilled hole diameter.
Stable drilling is realized for a wide range of work materials
  • The SG-ESR drill realizes stable machining for a wide range of work materials with improved chip breaking and chip removal.
  • The SG-ESS drill newly supports even smaller diameters (Ø0.5 to Ø1) that expands applications.
