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 (0.5 to 1) that expands applications.
