HSV-RN-4 | Carbide End Mills

Designed for smooth machining in deep pockets, the HSV-RN-4 features variable pitch geometry for decreased chatter and harmonics, as well as a reduced neck for maximum strength in long reach applications. Featuring an eccentric relief for maximum edge strength and an Aplus coating for improved performance in tough materials, this tool is a strong choice for a variety of applications.

  • Eccentric relief for maximum edge strength
  • Special geometry allows for both roughing and finishing applications
  • Variable pitch geometry results in higher quality parts by decreasing chatter and harmonics
  • Center cutting
  • Reduced neck provides maximum strength in long reach and deep pocketing applications
  • 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.
