DrillingSolidIndexableIndexableHead TypeInsert TypeReamersBrazedOthers Feed Rate f (mm/rev) Strong MultiDrills HY Type ■ General Features Strong MultiDrill HY Type is a 3-flute drill that achieves stability and high efficiency in machining of steel and cast iron, reducing the load on each flute and extending the tool life. J ■ Features and Applications ● High-Efficiency Drilling of Steel and Cast Iron Thick web and 3-point margin design ensure stable hole diameter accuracy in high-efficiency drilling. RY THINNING also reduces cutting force in high-efficiency drilling. Applicable 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 utilises nano-coating technology to provide more than double the tool life of conventional coatings. 3-point margin design gives excellent guide performance for vibration control and long, stable tool life. High Rigidity Evacuation Retains high rigidity with wide land. Drastically improved chip control and evacuation Reduces cutting vibration Improves chip evacuation ■ Product Range ● Drilling of general steel and gray cast iron CoolantSupply Cat.
