Aluminum & Non-Ferrous Alloys Roughing/Finishing

High Speed Machining (HSM) High Helix 2-flute Roughing/Finishing End Mill

Product Overview:

The HSM (High Speed Machining) is a high helix 2 flute rougher/finisher that uses the geometries of the ARF series and couples them with an extended reach design. The stub flute length, in conjunction with a wide range of reach lengths, makes the HSM series a great choice for roughing in aluminum and other non-ferrous materials in hard to reach depths of cuts.

Product Characteristics:

  • Flute Count (NOF): 2
  • Equal Index
  • Constant Helix
  • Center Cutting
  • RH-C / RH-H
  • Continuous Cutting Edge

Product Tolerances:

  • Shank Diameter (DCON): h6
  • Cutting Diameter (DC): -0.0001"/-0.0004"
  • Corner Radius (RE): +0.001"/-0.001"
