Went a bit farther afield for tag sales, and found a few goodies that I can use, including this..... smallest size, for 1/4-20, is missing, but I should be able to get one someplace..... 20 bucks the lot, in the die-cast metal box...(snazzy, probably collectible, as if I care).

I understand these are the best available for the purpose, so the problem may be handled.... at least for these sizes.

I would have thought the drills should be left-handed, or is it only the flutes that are RH?

Looks like a splined shaft that is pressed into the hole to get a grip for extraction?

Seems like a nice set, well worth the $20.

The drill is kind of beside the point. It just makes a hole for the splined rod to be pounded into, and then the nut-like devices on the left turn the splined shaft. So the handedness is no issue. I suppose LH they might extract the screw all by themselves. I could get LH drills for it if I wanted, the drills are standard sizes.

The things at bottom are drill guides to make sure you go down central and not out into the threads.

next time I have a busted screw, I'll give it a shot, and report back....

Yuup! You need to drill a left handed hole for the screw extractor to work.

I have had that same exact set for at least 50 years and it has removed a lot of screws. If you can drill completely thru the stuck screw it rarely fails. Of course, the usual aids like penetrating oil, heat, and vibration still help. I don't know who actually makes them but I have seen the same set with the Ridgid name on them. The two smaller ones tend to get damaged so keeping spares is a good idea.

The splined removers say Ridgid, so that would be Ridge Tools, div Emerson (or maybe Emerson sold them)
