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.

ZrN and TiB2 Coating Recommendations:

Benefits of High Helix Geometry:

  • High helix end mills are typically defined as possessing a helix greater than 30° (standard).

  • The helix angle determines the axial (along centerline) and radial (perpendicular to centerline) forces acted upon the mill as it removes material from the workpiece.

  • As the helix increases, the cutting edge length of engagement is lessened, resulting in an increased axial force component and a decreased radial force component.

  • Increased axial forces allow more effective chip evacuation and an improved finish on the workpiece.

  • Decreased radial forces reduce tool deflection and avoid tool breakage.

  • These features make high helix end mills suited for thin walled parts and other similarly demanding applications.

Rating StarRating StarRating StarRating StarRating Star   The best micro aluminum cutting end mill I have found

By Randy R. Endicott, NY, United States, March 02, 2014

My tool distributor JD Tool in NY gave me some of these to try about two years ago and now when ever I need an very small aluminum end mill I buy these. I run them to Harvey Tool's recommendations when able and they give me very good results. Our fastest spindle is only 15000 RPM and most of our machines are 12000 RPM but yet we do very well with these tools. I would like to see more sizes and most of all more lengths and corner Radius. Stock is good on these when ever I need them.
