Excellent surface quality and higher metal removal rates

The unique design allows to apply the tool in multiple passes, called “step down”.

Most tools leave tool marks with every pass they take, resulting in unsatisfactory or low-quality wall finishes. This usually requires another finishing pass at the very end of the process.

Mill 4-15 eliminates that finishing pass with an additional tool, saving time and money.

Features & Benefits

  • Double sided insert with 4 strong cutting edges per insert.
  • Low cutting forces due to highly positive geometry.
  • Applicable in steel, cast iron, stainless steel, non-ferrous materials, and high-temperature alloys. For roughing and finishing.
  • 90º shoulder milling with excellent wall and surface finish capabilities.
  • SGE-H geometry for helical milling. Cutter bodies available upon request.
  • Step down capability providing excellent wall and surface finishes.
