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.
Please don’t hesitate to contact our tech team with any questions at 800-645-5609 or tech@harveytool.com.

By Alan H. Abilene, TX, United States, January 22, 2014

I have been running the variable Helix end mills with a .010" corner radius in 316L, and I cannot believe the tool life. It is remarkable how amazing this tool is running. Keep up the good work guys, you just can't beat good ol' American ingenuity and hard work!
