When I talk to my supplier, they tell me the coating adds about 20% to the tool life. Well, thats all well and good for say a 1" endmill that costs $120 uncoated and $150 for coated. Its almost worth it...
But if I look at smaller endmills, say a 1/4", its about $10 uncoated and $15 coated. Go even smaller, like 1/8" and the coating doubles the endmill price!
Supplier says I can run a little faster with the coated, but not much, maybe 5-10%. Thats not enough to make it worthwhile for me.
So what do you guys think? This is just a general question for all materials and conditions, but in particular, I'm thinking about a job where I'll be working in 316SS with some small cutters.

These two companies will explain coatings better than I can. Uncoated for like Titanium materials, and Coated for just about everything else. Coatings help to keep an End Mills cutting edges sharp, from breaking down, or heating up too much. Coatings also help chip evacuation by providing a smoother cutting surface.
