This is the one.What kind of accuracy and repeat-ability are you looking for? I just usually take a fly cutter and grind a 45 degree tool bit and have at it. Couple of other ways, angle your vise or make a vee block for the stock to reside in.
Don't know if Shars' "blackfriday" code will work on eBay purchases. But you can get the same set for $47.70 (70¢ more), plus the discount (and probably comparable shipping) by going to:Searching ‘single angle inverted dovetail cutter’ and ‘single angle chamfer’ did the trick and filtered out all wood router bits. I ended up going with an indexable set as I could use them for some other stuff I need coming up. Thanks!
