Hello,
I wanted to introduce you to our newest technical assistance idea called the Milling Advisor. This milling calculator is available on the Apple, Droid or PC platforms and does not cost you a dime! It's a way for us to bring you good accurate speeds-n-feeds for our high performance tooling. Check us out at www.1helical.com.
For the app, just check your app stores and search for Milling Advisor or for the PC head to (VoluMill) and download it there.
I can answer any questions you may have about it or any of our tooling!
