once sharpened the coating is removed.

with regular drill bits the coating still helps minimize heat and friction caused by the side of the drill as it goes into deep holes, but with lathe tools I’m not sure how much of a benefit you’ll get from it given that the first time you’ll resharpen the edges the TiN coating will be lost. I wonder how Sorby is marketing this
