Re: Drill bits
I agree with Barry.
Only a coating, so once you sharpen a drill, any magic has to be gone, and the performance of a new 'titanium' drill seems indistinguishable from a normal HSS drill, so I suspect the magic is entirely in the marketing.
Looks pretty on sets of bits on display in DIY sheds.
