Split point is the reason this one earns the top spot. A plain point skates across steel until it finds a bite; grind a small facet across the tip and the bit starts cutting where you put it. The 500X both restores an existing split point and cuts a new one, and the Push to Stop port ends the grind before the facet runs long, which is the mistake that turns a useful bit into a scraper.
Two point angles cover most of what sits in a home index: 118 degrees is the grind your bits came with, and 135 holds up better in hard material and stays on line in a handheld drill. The chuck takes 3/32 to 1/2 inch, where nearly every bit people actually wear out lives, and a 3/4-inch chuck is sold separately for the ones that don't. Carbide, cobalt, black oxide, TiN and masonry bits all go through it on the same diamond wheel.
Setup is where we paid closest attention, because alignment is where a sharpener either works or quietly ruins an afternoon's worth of bits. Of the electric models here this is the one that asks least: the chuck indexes the bit, and by the third or fourth one you stop thinking about the sequence. One thing to know before the first bit: the white dots on the chuck aren't the alignment marks, whatever they look like, so follow the manual's line instead.
In the box you get the 1/2-inch chuck, a 180-grit diamond wheel already fitted, a hub wrench and a six-foot cord, backed by a three-year warranty. No bench grinder to mount, no second jig to buy. It lives within arm's reach of the drill press here, which is the highest compliment a shop tool gets.
Bottom line: The one we recommend first: split-point sharpening, a choice of 118 or 135 degrees, and the least demanding setup of the electric sharpeners here.
