SG FLAT Drills

●Flat drills made of HSS superior in cost performance

○ Realize stable drilling of larger flat-bottom holes with the adoption of high alloy HSS(FMX) and SG coating.
○ Size range : Ø16 to Ø50

●Well balance between rigidity and chip evacuation with the adoption of optimal flute geometry

○ Restrain hole expansion and realize the drilling of high accurate flat-bottom holes.

●Adoption of Gash land

○ Improve chipping resistance on the corner of cutting edge and realize longer tool life.
