NACHI L/N 7574 SGESR High Performance Drill with SG COATING / Mata Bor SG Coating 22.5mm 22.5 mm

NACHI SG-ESR DRILL Diameter = 22.5 mm Flute = 150 mm OAL = 218 mm Shank Dia = 25 mm 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. SG DRILL SERIES Time amp; Process Reduction Extremely precise positioning and stable drilled hole diameter allows cutting down on the reaming process. Powder Metal HSS allows for high speed, high feed cutting Nachi #39;s SG coating allows for high wear resistance and longer tool life SG Coating Specialized Film for Drill with Fine Structure Fine and multiple layer structure improve rigidity and wear-resistance JENIS JENIS NACHI SG SERIES 1.
