The HSS ground drill bit is made of heavy-duty high-speed steel (M2) plus Titanium Nitride Coating (TiN)
The TiN wear-resistant coating increases the surface hardness and the heat resistance. Achieves longer tool life
Split Point (118° point angle)
Application areas: for steel, alloyed and unalloyed cast iron (up to 900 N/mm²), metal, wood and plastic
Such as: grey, malleable, ductile and die-cast iron, sintered iron, nickel silver, brass and bronze, short chipping aluminum alloys
RUKO high performance ground drill bit consisting of heavy-duty high-speed steel (M2) plus TiN coating. The TiN wear-resistant coating increases the surface hardness and the heat resistance. Achieves longer tool life! The fully ground drill bit has a more precise concentricity. Application areas: for steel, alloyed and unalloyed cast iron (up to a strength of 900 N/mm²), grey, malleable, ductile and die-cast iron, sintered iron, nickel silver, graphite, short chipping aluminum alloys, brass and bronze.
