Work Material : FC250Tool : Conventional Tool,MDW1250HX5（ø12.5mm 5D）

Cutting Conditions : v =100 m/min, f = 0.60mm/rev, H=50 mm, Internal Coolant (Water Soluble) c

Long tool life Reduced cutting edge wear with extended tool life even at high feedrates. → Maintains replacement frequency (cutting time) and enables high efficiency drilling.
