Beskrivelse
Consisting of: 25 twist drills DIN 338 type N HSS-TiN ground Ø 1,0 mm up to 13,0 mm in increments of 0,5 mm
– High performance ground twist drill consisting of heavy-duty high speed steel. The fully ground twist drill has a more precise concentricity. The TiN wear resistant coating increases the surface hardness to approx. 2,300 HV and the heat resistance to 600 °C. Achieves longer tool life with increased cutting values.
Application areas: for steel, alloyed and unalloyed cast iron (up to a strength of 1100 N/mm²), grey, malleable, ductile and die-cast iron, sintered iron, nickel silver, graphite, short chipping aluminium alloys, brass and bronze.
