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

Definitely works better than other cheaper brands.

Accurate and repeatable

I ALMOST went with a laser edge finder, but this tool was chosen instead (a lot less expensive) and I have to say it is one of the best quality tools for this price I have ever purchased.

Good

This product doesnt seem to be an actual Mitutoyo edge finder, rather it is likely a generic copy. It seems to work but is not as accurate as I had hoped. Its fairly difficult to determine when to stop, and I had been under the misconception that there would be an audible indication as well. If there is an audible indication I cannot hear it over the sound of my milling machine motor (which isnt very loud, to be honest). I will admit that it could be operator error and that I may get better at using it with time.

Worked like it should worth the buy.

Found the edge. Want to share a tip that has helped me a lot with CNC milling. Example: find the left side, set x to 0. Find the right side. Lets say it was 11.2763. Move edge Finder above top of part. Enter this gcode - G1 X[11.2763/2] f5. It does the math for you, no need to pull out the calculator, it takes you to the center; set x to 0. You are welcome.

I needed to get this for working on the mills at school I am learning to become a machinist so tight budget & this works just as good as a higher priced one.

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

Dont know if it was because of cheap materials or what but it got rusted fast so after every use need the clean it and oil it not something that I had to do before
