Strong MultiDrills HX Type
■ General Features Strong MultiDrill HX Type is a special drill for cast iron that combines reduced cutting resistance and improved drill strength to achieve stable and high efficiency drilling of cast iron.
Chip control + evacuation drastically improved
J
■ Features and Applications ● High-Efficiency Drilling of Cast Iron
50 Thick web and special double margin design ensure stable behavior even in high-efficiency drilling. Furthermore, RX THINNING drastically reduces cutting force and ensures more stable and efficient drilling. Enables high-efficiency drilling at speeds of over v f =39.4 IPM. (for ø10mm sizes) ● Long Tool Life DEX Coat for drills utilizes nano-coating technology that provides
DEX Coat
more than double the tool life of conventional coatings. The drill guide function is enhanced through optimization of the margin position to prevent breakage due to hole bending.
