shaft roughing\finishing cutter long

• Shank roughing/finishing cutter long HSS Co8

  Long high-performance shank cutter to DIN 844 with
  Weldon clamping surface according to DIN 1835B.
  Roughing/finishing cutter for large-area milling work,
  type NR P for pre-machining and finishing of materials
  with a strength of up to 1,100 N/mm2.
  3 cutting edges on the face and cutter circumference for
  machining surfaces, shoulders and corners. One tooth
  cutting over the centre for drilling.
  High- speed steel with 8% cobalt for machining
  tempered and tool steel, structural steel, cast iron and
  non-ferrous metal.
  High toughness and perfect heat resistance,
  very long service life. Frequently selected type for high
  cutting speed and productivity.
  Roughing/finishing profile for maximum cutting performance,
  suitable for hard and /or short-chipping materials.
  The average roughness of the finished surface is
  ? Ra 3.2 ?m. The surface
  quality is sufficient in many cases.
  Tool geometry with a twist angle of 35° for
  a well-balanced distribution of cutting forces,
  rake angle 12° for materials with low to medium
  strength.
