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

Item is to small for other than very small piece work

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.

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

seems silly however I can eyeball the edge only close. this thing will save me some time!

Its a mitotoyo, it works as it should is made of the highest quality. Gets me on point every single time. Very happy.

It could use a little hand finishing to remove a burr here and there. After about 5 minutes of finishing it works great.

Great edge finder for the manual mill. This is a replacement for a Starrett edge finder that broke and it is every bit as well made and high quality. I also ordered a few cheap Chinese edge finders and wish I had not. In terms of quality this is a far superior tool

Works good and excellent price.

This thing works very well, is very accurate, and find that I can get an edge location to about 0.001 just fine. I have made the error of driving it hard into my stock along the Z-axis a couple of times and it still keeps going! It is also very forgiving when over driven horizontally. When using it I typically turn the spindle at about 100-300 rpm so that the miss-alignment wobble is very visible. I have used it against mild steel, Al, and plastic and there is no visible wear on the tool. I should purchase a spare or two.

Insane value. Quality edge finders, cheap. I use them in the shop and havent had an issue.
