End Sharpening is the term, but not precise; it's the corners. The dove tail or concave section cuts only when plunging, but the small periphery area inside and corners normally get beat 100% of the time. The sides, aka flutes, have the most reinforcement behind edge by margin and relief. Proper feeds and speeds are calculated to save flutes, not ends. Any home shops have 2-4-6 flute endmills in their choice of diameters? Not many.
Sharpening at home shop level is not an easy sell. 1260 does buy a lot of end mills. Just once though.
One favorite advertising pitch were early Darex, the drill grinder. A simple photoshop, drill bit tip and part of length, morphed into a lead pencil and eraser.
It said "Pencils are .11¢. You sharpen those, don't you?
Who makes setups to run the upper edges of flutes? Those who buy our own, that's who. I seek out those trays of used end mills, having full array of grinding equipment to rescue them. But no Darex.
