ALDH Aluminum Double Helix Roughing End Mill

Product Overview:

The ALDH (Aluminum Double Helix) is the rougher of choice for aluminum when optimum material removal rates are the objective. The combination of progressive double helix geometries result in a cutting tool intended for full engagement cuts at increased feed rates. Slotting cuts of 1x the diameter or more are normally recommended. 50% greater IPM versus competitors 2 flute design is a conservative starting point. 

Product Characteristics:

  • Flute Count (NOF): 3
  • Equal Index
  • Double Helix
  • Center Cutting
  • RH-C / RH-H
  • Continuous Cutting Edge

Product Tolerances:

  • Shank Diameter (DCON): h5
  • Cutting Diameter (DC): -0.0001"/-0.0004"
  • Corner Radius (RE): +0.001"/-0.001"
