Why is one listed for $11 and two pack $75? Am I missing something or was that a typo?

Just buy 2 at the $11 each price.

Is it adjustable? Does it have something on the upper end to tighten it?

its .200 on the small end,.400 on the large. you use it by chucking up the larger end into either a collet or drill chuck,turn on the spindle and touch it to the edge of the workpiece until the wobble or runout runs true,then zero out your readouts or set dial to zero,then move negitive .100 which is half of .200 and that puts the spindle dead on the edge of the workpiece,then you can calculate any machining off of that

What is the safe max RPM rating for this edge finder?

They are designed to run roughly 1400 rpms, this has to do with the spring tension etc. I wouldn't go faster than 2000. After that the spring expands and can become inaccurate. Much faster than that and they can explode.... don't ask how I know.

Can you tell me this item 050101 had Mitutoyo stamp on it or not? And how do you know where it made from? I saw on pic show nothing on there.

no I.D. on the edge finder. case has mitutoyo america sticker on it. works fine no problem with it.

Better then Starrett at this point

Works just as well as the Starrett ones which have gotten to an insane price point anymore so why bother with those when these Mitutoyo ones work just as well? They are built well, work well and my pick ups have been well within 2-4 thou
