   I have a drill doctor, and it's very good. It's a little problematic for really small bits, but it's great for everything else. I forget which model this is, but I chose this one because it will take 1/2" bits. The 750x, maybe?

   Another drill doctor user here. After a short learning period, no complaints.

   I had one and found it to be more effort than it was worth. I gave it way through this forum and I'm happy to have the drawer space back.
   I buy bits in bulk packs, sharpening them is not how I want to spend my shop time and the screetch of that thing was horrific.

   I toss out the small ones. Anything under maybe 1/4" or so. I was doing a lot of wiring using 12" long 1/2" twist bits, and they were pricey. Hitting nails was unavoidable. The Drill Doctor saved me a ton of dough.

   These days I use 1/16 and 5/64 bits, a lot. I wouldn't even consider trying to resharpen them.

   Drill Dr 750x is not BAD (and probably all you need), but BEST? Black Diamond probably, until you get into "Production drill bit sharpening" - I mean a Darex V390 makes a 750x look like a toy, and then there are specialty cutter grinders, and CNC units - Want to know how to sharpen spur buts? You aren't doing on any of the consumer stuff.
   And yeah, pretty much under 1/8 (and even there) the best drill sharpener is a good machine tool catalog, and ordering the bits by the dozen

   I hesitate to post this because I don't want to troll. There are techniques that allow you to sharpen bits on a simple bench grinder. It's all hand feel but once the muscle memory is attached it's super fast. Like anything smaller bits are a challenge. Anything smaller than 1/8" is hopeless with my 50 yo eyes. You are on the 70th floor of a high rises and have 4 more hole to drill to finish an install. All your bits are dull. You have an angle grinder though. That's what started it.

   Yep, Hand sharpening isn't HARD, but unless you get good at it, you tend to make one edge longer than the other, or a slightly different angle, and the drill makes an oversize hole. Above 3/4", it is the only way I have. I got a Dr Doctor (the original toaster style) the first Christmas they existed. I gave that one to a robotics team, and got the new style a few years back. Way faster than doing it by hand, particularly if splitting points.
