Speeds & Feeds for Harvey Tool's Miniature Variable Helix End Mills (Optimized for Aluminum & Aluminum Alloys):


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.
