Mitutoyo050103, Edge/Center Finder, 3/8" Diameter Shank, 0.200" Diameter Tip

Great quality. It works as expected and would recommend it to anyone.

Good quality. I read other reviews that complained of breakage but I can see that because the edge finder has two working ends, when removing it from a collet care must be taken to avoid having the collet hold one end when you are pulling on the body, causing the body to pull away from the end still inside the collet. Best to remove the collet from the collet holder and push the whole edge finder through the collet instead of trying to pull it out. Or buy single ended edge finders.

You may pay more for this than the Chinese version but it's guranteed to work flawlessly for a lifetime. So why not pay a little more, buy it once, use it with no issues, and just enjoy a quality tool that makes it fun to use.

Works great, my second one because I dropped my other one.

9 months of use and it has developed a burr or something that inhibits smooth motion. The obvious 'break' that is suppose to occur has subsided to a very slight shift which makes me have to rely on maths on the DRO (part dimension + .200) to verify accuracy...It was a nice edge finder but I'll be trying other brands as I've found Starret edge finders to be a finer ground mating surfaces. Brown and Sharpe has an edge finder for sale for a similar price so I'll give that a try as well.

This is one of those "how did I ever do without it" gadgets. It is nicely ground and seems to be accurate and durable. I use it in the drill press to locate holes that should be precisely positioned. Mount it in chuck with the pointed end down, spin it at about 1000 RPM, and gently push against the side of the point with a small stick until it runs without any wobble. Turn off the motor. The point is now exactly aligned with the center of your chuck. If you have accurately scribed cross lines on your workpiece, you can center the point above them visually. (Magnification helps.) Clamp the workpiece in place, swap out the center finder for a center drill, and you're ready to go. It's pretty easy to get a hole aligned within about 0.005 of true position this way. You can also locate the center of an existing hole by centering it visually or by dropping the point into the hole and moving the workpiece until the point is concentric with the body.The other cylindrical end locates the edges of work exactly. It's useful in a milling machine or a drill press with an X-Y table or vise. Again, spin it at about 1000 RPM, nudge gently until the cylinder spins true (no wobble). Now slowly move your workpiece up to the spinning cylinder. When it just touches, the tip of the edge finder will "step" to one side visibly. At this point, the center of your chuck is offset from the work by exactly half the diameter of the tip (0.100 inch). The point at which the side-stepping action occurs seems to be consistent within 0.001 inch. With an X-Y table, you can now crank in the exact dimension you need.

Its quality i can trust....

There are some that are as good as mitutoyo in my opinion, but very few, if any, better. Mitutoyo is one of the best machine tool tech brands out there. This works great to locate small hole centers, center punch marks as well as normal edge finding in the knee mill.

This works just as it should
