HYHigh Efficiency Solid Carbide Strong MultiDrill
■ 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 v =800mm/min in steel drilling and v =1,000mm/min in cast iron drilling (for ø10mm sizes).
f f
- 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
