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

Good product so far

I’ve been using thisede finds r for a few weeks now, I have no complaints. It works just as intended and is very accurate.

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

I dont know who makes this as it has no markings on it. But it does work very well for edge finding on my bridgeport.

Good edge finder, reads spot on with my Lagune DRO. It does leave a slight mark on softer materials (aluminum/plastics) unlike my Starrett though, not sure why this is and am docking it a star for the issue.

Accurate and repeatable

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.

Works as advertised. It will find the edge of a work-piece within .001-.002 consistently. I recently used it to relocate a hole that needed a deeper counterbore so I used the edger finder to get me in the ball park. After dial indicating the hole the DRO showed the difference to be .001 on the Y axis and .002 on the X. Great tool!

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.

Worth the money over the cheap stuff
