its a game plan that works quite well i agree altho if your trying to remove a stud thats buried with a lot of surrounding land then its less effective altho anything is a help.+1, if they're seized then weld a nut on to the stud and pour cold water over it. I've yet to find a stud that wouldn't come out with this method.

ive been trying the acetone and ATf mix to see if what they are saying is credible in my world, ive refilled it a few times to my surprise, the acetone wicks in quicker (for what it can) than the likes of wd, it draws in some oil for lube with it, only downside is it separates but a quick shake gets it back in order.
i was waiting for that question to come up.
i have a few of them here and altho a good drill i keep em mostly for the mill and lathe.
the pattern is a grand idea but sharpening them is the one downside to them imo, id imagine when it comes to the first or second sharp for most its lookin more like a std drill than what it once was.
to sharpen it as it originally was id be a challenge for anyone not used to sharpening drills.
it is possible to do it tho but you need a well dressed, well cornered wheel.
my man tom here is a smart cookie, this video would help you practice and learn if you were interested.
or you could just buy a drill sharpener, and im not talking about a drill doctor there either, i personally dont rate them but i understand why a lot do.
start with the bigger bits they are much easier to see the right angles on,I have a 60 degree angle marked on the tool rest on my grinder, takes out the guess work@tinman Well D, after watching this video I picked up a bench grinder this morning. Nothing special, a 6” Jefferson for under €100. Should be fine for drill bits and the like I’d say. 2850 rpm. I have some old but good quality bits which I’m sure could be rejuvenated with a new edge. Some must be 60+ years old and belonged to an ancestor who was into lathes and the like.

rough em out with the coarse wheel if you really have to and finish with the fine one.
its a trial and error game, had a lecturer at a college who could put a damn fine edge on a bit by the eye and when gauged up was pretty damn close in fairness, i asked him how long he was sharpening drills for and he said over 30 years and he was still learning how to do it right....
you could get yourself a drill gauge, quality ones on the bay are sharp but less would do.
or the two nuts together trick is fiddly but acurate enough.
maybe get jiggy with the grinder table and fashion up cork version, what with a guide that ill slide on the edge of it to keep you on the angle, there be videos of such contraptions.
or there's the controversial drill bit sharpener add-on if you want to cheat a bit.
either way in no time at all you'll be dishing out the likes of this beauty...
What exactly will a cobalt drill make a hole through then, and will it do it repeatedly? Never bought any.
