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. Iā€™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 5/64ā€ to 1-1/16ā€ (2 mm - 26 mm) range, should no longer be an issue.

Got the larger one last night.....damn it is heavy.

Pried off the entrails of a wood box, and it looks like it's all there, and the motor
sounds quiet.

will try it later on.

Thank you again for the heads up, I have looked at them for years, but they were always much more expensive.

I got one of the drill doctors. It's mostly plastic, and works better than I can do it freehand. Of course, I cannot sharpen drills freehand at all. Once I've sharpened a dull drill, it definitely cuts better, and I really can't tell that the two edges are different lengths and it's wobbling and cutting oversize. I'm not doing precision work, so it doesn't matter if it's a bit off.

Finally tested it out.

Works very well.
I would like to suggest the fan on the grinding wheel, would be nice
if it had a duct out back to suction all the grit out of the way.

My concern is those nice, accurate bores & mechanisms will get
damaged by all of it just "flying around".

I've looked at the smaller one, however the price is still double
of the larger one.

I wonder if I could just buy a set of collets for the smaller drills, and run them on the big one ?

I paid $239 including shipping.

Much better all around than the DD.

I have used it, works well.
don't recall the vendor, only that the sale price is now gone.
Have not any end mills, sold milling machine years ago.

EDIT: now that the 2-13mm grinder price has come down, I just looked at them.
I only see (2) holes for grinding, it appears these machine don't doo the split point.

The larger ones (13-26mm) have 3 holes, doo a very nice split point.

Better than the drill doctor is really a pretty low bar. If I had known about this option, I would have gone with it. The DD is good enough for my very low precision needs, so I probably won't upgrade.

I thought a DD was very good at what it does. Yes, I went to the better units, more for consistently good results. If I had not bought the better units, I could have survived with the DD.

I have one of the first ones ever made and it still works just fine.
THE STORY:
Back in the dim dark ages before I retired (which has been 23 years now) there
was a thing called "Usenet" . I followed "Rec Woodworking" and "Rec Crafts Metalworking". There appeared a post from some sort of a "sales man" or advertising person regarding this thing called a Drill Doctor with a lot of talk etc. and the offer of several free ones for a message detailing why one would like to have it and any other pertinent things. So ginned up a nice note and fired it off to him. Lo and Behold about a week or maybe two later the package arrived with it I've been using it ever since. :-)
