Mitutoyo 050101, Edge Finder, 3/8 Dia. Shank, .200 Dia. Tip

Just what I needed.

I gave it a 4 star for accuracy because I have not used it yet, but I looks as it should.

Nice little edge finder.

Works as should

Buen edge finder y excelente precio

Not cheap quality. Accurate within .002 sturdy get value

I recently installed a tang peep sight on a Winchester 9422 rifle. The work required drilling two holes in my beautiful, discontinued firearm. Margin of error was zero. Using this edge finder, I easily located the right spot, drilled, tapped, and mounted the sight. Perfection. Works as advertised. Get one if you want to locate your work to .001 or even better.

At $10, its hard to believe this is really a Mitutoyo branded tool, but it is. Quality is fantastic, very precise and repeatable, down to about a hundredth of a millimeter (as far as I can take it). I much prefer the cylinder style edge finders to the conical style edge/center finders. Its good to have one of the conical type in your toolbox for occasional use on small holes, but 99.9% of the time, this is the one Im reaching for.

With a name like this has, what can you say negative?? Works great! I’m nervous of the battery powered ones, this has no drawbacks.

Perfect grind, absolute mechanical perfection. Instantly, repeatably, and very visibly gets you within a couple tenths (0,005mm) every time.
