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.

Harvey Tool's Miniature Variable Helix End Mills (Optimized for Aluminum & Aluminum Alloys) are stocked Uncoated, TiB2 Coated and Amorphous Diamond Coated. 

TiB2 is best used in Non-Abrasive Aluminum Alloys, Magnesium Alloys.  Primary benefit over other non-ferrous coatings is extremely low affinity to aluminum.  Prevents build-up on cutting edge, chip packing and extends tool life.  

Amorphous Diamond has outstanding performance in Copper, Brass, Bronze and High Silicon Aluminum.  Hard diamond layer improves wear resistance and lubricity. Thin film coating maintains sharp edge which improves performance and finish.
