●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.
Flute Geometry of SG-ESR
SG Coating
○ Specialized Film for Drill with Fine Structure
○ Fine and multiple layer structure improve rigidity and wear-resistance
Fibrous precise films can control fatigue crack propagation and prevent the big damage to coating film
