Choosing the Right End Mill

The easiest way to select the correct end mill for your application is to look at our application tools for various materials!  

Once you know which end mill style you need just click on the slide with that to go directly to the tool details
At Destiny Tool we make a very niche selection of material specific cutting tools for the Aerospace, Defense, Medical, Automotive, Computer and Wafer Manufacturing industries.  

The tools are made with very specific geometries, substrates and coatings to provide the maximum chip removal rates and high attainable cutting speeds and feeds to help you make more parts faster and cheaper. 
Good Shop Practice


Select the shortest flute length possible for the application. Shorter flute length end mills offer better stability and increased feed rates.

Select the largest diameter possible for the application. Increasing diameter by 10% provides 25% more strength.
