Grinder might be nice too, not sure about that learning curve.
If you had someone to show you how, you'd pick it up in a couple minutes.
Seems as this is becoming a lost art just like putting a logger's splice in wire rope.

there's a few different versions. the lower model - the 350 only does one tip angle - 118 degrees and doesn't do split points. the 500 will do angles from 118 to 135 degrees and split points. there's also a couple other models too, but those two are the most common. looking at the site, the 350 doesn't list cobalt drill capability. maybe they use a different sharpening wheel? i've been considering getting one, but if and when i do i'll likely go for the 500. sadly, it's around $100 here.
Just checked and it's the model 350 that's on-sale. I guess I'll look for the 500 or better the 750. I've tried the grinder but have not had much luck with it.
I just checked lowes.com site and they sell the DD350x for $49.99 and the XP for $79.98. Lowes.ca does not even list any Drill Doctor.
Homedepot.com has the 750X for $159 and the XP2 for $79.
i thought i had read that you could buy the 3/4 adapter and use it in the 500 sharpener, but maybe i'm wrong - the drill doctor site shows the 750 being able to do a slightly different range of angles, so maybe the base unit is different. for bits over 1/2" i'm generally comfortable hand sharpening them, but for smaller ones i'm not. it's not just a matter of being able to grind a sharp point that will cut, it's making it so that both cutting edges are identical.
in the last couple years i've done more "precision" work, and i want my smaller bits to be as true as possible so the holes go as straight as possible. i've made a lot of smaller parts where i need to have multiple holes line up precisely. there's no oversize drilling allowed for stuff like this, and i don't want a bit where one side leads the other and the hole wanders or ends up slightly off. this is mostly for small stuff. if i needed precise holes that are larger i'd probably bore them instead of drill them.
