High performance sharpened twist drill made of High Strength Steel (HSS). The fully sharpened twist drill has an increased radial run-out. The TiN coating increases surface hardness to about 2,300 HV and heat resistance up to 600ºC. This results in a longer tool life with increased cutting values.
for steel, alloyed and unalloyed cast steel (up to 1100 N/mm2 strength), grey, tempered, nodular- and spray cast iron, sintered iron, nickel silver, graphite, short machined aluminium alloys, brass and bronze.
