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.
- Extremely precise positioning and Stable drilled hole diameter.
- 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 (0.5 to 1) that expands applications.
