I found this brochure to be very helpful: https://marketing.da...ool Catalog.pdf

My own easy maybe over simplistic observation is use one type of end mill per material type optimized for each material and dont mix them. Keep cutting length short. Follow guidance and dont use guesswork or your ear. There is 100 years of experience out there, use it. Use smaller tools for harder materials and dont get greedy unless you like to see broken bits fly through the air. Dont watch your work up close unless you want to lose an eye. I will rig up my GoPro (I knew I got it for some reason) and you can watch me!

Reminds me I need a new prescription for my cool safety glasses.

A lot of very useful information but I was left a bit confused - the tool descriptions cite coatings but not tool material but when I scrolled down to "tool technology" it referenced "solid micro grain carbide"  I wonder if this applies to all of their tools.

$293.94 for German Carbide Cutting Tools.

This is just an example of small, approximately 1/8 inch cutting tools can cost. American or even Chinese tools would/could be a lot less of course. Bigger sizes are a lot more expensive but with my mill and cutting metal, this would not be a good idea or realistic. Now I need to find a place that sharpens cutting tools.

Yep, but you also might want to add face mask as well.
