High Efficiency Solid Carbide Strong MultiDrill HY Type ■ General Features Strong MultiDrill HY Series is a three-flute drill that provides stable, high-efficiency drilling of steel and cast iron, reducing the load placed on each cutting edge and ensuring long tool life. ■ Characteristics · Applications ● High-efficiency drilling of steel and cast iron Thick web and 3-point margin design ensure stable hole accuracy in high-efficiency drilling. Furthermore, RY THINNING reduces cutting resistance in high-efficiency drilling. Corresponds to cutting conditions exceeding vf=800mm/min in steel drilling and vf=1,000mm/min in cast iron drilling (for ø10mm sizes). ● Long tool life DEX Coat for drills utilizes nano-coating technology that achieves more than double the tool life of conventional coatings. Three-point margin design provides excellent guide performance to achieve vibration control, stable and extended tool life. High Rigidity Evacuation Retains high rigidity with wide land. Significantly improved chip control and evacuation Reduces cutting vibration Improves chip evacuation J ■ Series ● General Steel･Gray Cast Iron Drilling Drilling Coolant Supply Cat.
