Last Sunday Night, I finally broke down and bought a new motorized drill bit sharpener a MR-26A, that sharpens all bits between 13 - 26 mm (1/2” to 1-1/16”) drill bits.
It arrived at the home shop on Thursday, the wife bitched loudly, as it weighed 65#. The unit uses ER 40 collets (supplied withe the unit) to hold the drill bit accurately, while being sharpened. You set the diameter, set the drill in the collet chuck, then sharpen the drill bit, then you can split the point, if you want to.
Today I sharpened about 50 drill bits, ranging from 1/2” to 15/16”, I very impressed, with the ease of the procedure and the speed of the procedure. I did one 3/4” bit that looked like an enraged badger had gnawed on it and in less than a minute, it was better than new.
Welp!! I was so impressed, that after my phone conversation with MiloMilo, I bought the MR-13A version that does 3 - 13 mm (1/8” - 1/2”) drill bits. It should be here by next Friday.

Thats quite a bit nicer than my POS drill doctor.
If you need some more practice on it I can send you a couple hundred bits in various states of dullness.

That looks very nice and doesn't take up a lot of room.

I don't think I want to know what it costs.

Sounds good, looks like a heckuva unit, have you tried the drills after sharpening?

Welp!! After being told it would be delivered between 11/17 - 11/24, the smaller MR-13B arrived by DHL currier at 1:30 pm, today. I’m in the process of getting ready for the trip to Kansas in the morning, but I had to try it out before I left. It work jut like the bigger MR-26A unit, the results were spectacular. The unit is about 1/3 the size and weight of the bigger unit. So dull drill bits in the 5/64” to 1-1/16” (2 mm - 26 mm) range, should no longer be an issue.

I like the little one. It is reasonably priced if you have regular work for it.
-
Those would pay for themselves pretty quickly. ~1 hour to sharpen 50 bits, nice.
Looks pretty straightforward to sharpen bits..

I've seen many of these models sold on AliExpress Walrus.
Prices are good, but shipping is usually the stickler.

I bough mine from Amazon, the mr-26a for roughly $310 and the mr-13b from eBay for roughly $425
