Features

  • High speed steel (HSS) provides good wear resistance, it is commonly used for general purpose applications on both ferrous and non-ferrous materials
  • Titanium nitride (TiN) is a multi-purpose coating which increases chip flow in softer materials and the heat and hardness resistance allows the tool to run at higher speeds than uncoated tools
  • 90 deg cutting edge
  • 1.562 in L minimum clamping
  • 30 deg axial rake
  • 10 deg radial rake
  • 1-1/2 in L reach
  • 0.2 in Dia neck
  • Square nose end mills create sharp, unrounded cuts
  • Extended-reach neck style provides access to recessed areas of the workpiece
  • Center cutting design allows the end mill to plunge into material like a drill bit while also performing conventional surface milling
  • G - Step Neck tool shape
