Yes, not too hard puting on a corner chamfer yourself. But how about putting on the Tialn coating yourself?
I'd do that just like they do to the "Titanium" drill bits at lowes and Horrible Freight.. But instead
of gold spray paint, I'd use a purple magic marker.
I have a question for you, since I know you know your "stuff"... Where on the endmill do you actually need the
slippery stuff? Where is it most important? Isn't the greatest heat and pressure just behind the cutting edge on
the inside of the flute?? "in theory" the outside of the endmill should NEVER even contact the metal being cut, though
in reality if there is any deformation of metal at the cut, the outside of the endmill would rub a bit just behind
the cutting edge, climbing of course, the outside of the endmill would take a beating in a conventional cut.
This person needs to make 1,000pcs. So your going to need to grind 2 or 3 endmills yourself by hand and make sure all of them are very close in size. I don't know how much your time is worth but these endmills are $11.81 each. Tialn coated and all features ground in one operation so all 4 flutes cut right.
I did say my preferred method is off the shelf.. And I probably couldn't even
buy a good package of dark purple (plum?) magic markers for $12. Back in the old
times I didn't even know you could buy endmills with radius's and chamfers, I always
made my own. Now I keep stock of .015,.030,.060,.090 and .120 rads in house.
