  on machine tools with Morse taper attachment.
  High-speed steel for drilling in
  structural steel, cast iron, non-ferrous metal and aluminium.
  ?14 mm models with cross grinding to
  DIN 1412 C for tough and hard materials,
  castings and forged workpieces. Good
  centring, low feed force, good
  chip removal due to chip separation, resistant
  to impact.
