Chamfer Mills - Helical Flute, 3 & 5 Flute - High Performance

HPCM | Carbide End Mills

Introduced in 2016, the HPCM is a completely unique chamfer cutter design. The helical flute geometry and flat tip geometry provide significant boosts in performance over straight-fluted chamfer cutters, and the high flute count and Aplus coating make these tools capable of handling tough applications.

  • 3 and 5 flute options helically ground with positive axial rake and clearance
  • Helical flute geometry results in superior part finish
  • Flat tip diameter for programming accuracy and increased strength
  • h6 shank tolerance for high precision tool holders
  • Aplus coated for added lubricity, higher speeds and feeds, and increased wear resistance

Below are downloadable Simulation Files in DXF format (half-round line drawings) to accompany Harvey Tool products. Each file is specifically scaled to the geometry of the tool to help simulate running parameters and create tool paths. Like our speeds & feeds charts, these files will be continuously updated with the introduction of new products and new catalogs to assist operating the majority of our tools. Simulation files can also be accessed by searching for a specific tool number on the left-hand side of the website and then clicking on the Simulation table in the product table.
