The Mitutoyo 129-127 depth micrometer has a measurement range of 0 to 4" and a resolution (or smallest graduation interval) of 0.001". The vernier scale provides precise measurements, and it includes four interchangeable 0.157"diameter measuring rods for flexibility in measuring range. The gauge has a ratchet stop for uniform pressure and a measuring rod clamp for stability. It has a satin chrome finish on the body for readability and the base is made of hardened steel for durability and accuracy. It comes in a fitted plastic case. This depth micrometer is suitable for precise measurement in a variety of manufacturing, machining, and mechanical engineering applications.
Depth gauges are precision measuring instruments used to determine the depth of any shape that has a step, groove, or slot. These gauges often take the form of sliders that travel on a measuring beam or rods, are moved to position by hand, and then adjusted with a calibrated screw. The base of the gauge rests at the top of the shape whose recession is to be measured, while the beam or rods extend to the bottom of the recession to determine the measurement. Gauge position is read from a graduated scale, dial, counters, or an electronic display.
Mitutoyo manufactures precision measuring tools, metrology equipment, and related systems. The company, founded in Tokyo in 1934, formed Mitutoyo America Corporation in 1963 with headquarters in Aurora, IL.

I work in a machine shop and was in need of a depth micrometer. I know Mitutoyo is known for their quality so this was my first choice naturally. I received it within a couple days and it works perfect for me. You really can't go wrong with it. Measuring things is simple an much easier with this tool. I'd definitely recommend this to anyone in need of a quality depth mic.

Works great. Wish it could read 0.0001" but that's all

Eventually you will have this tool go out of tolerance by a thousandth or 2. Trying to understand the instructions is an impossible feat. They should call IKEA up and get them to write picto-graph instructions to set the multiple bars over or under to get it back to zero.If you own this, you should really also own a set of gauge blocks or have access to a standard to make sure it is measuring correct. I still think Mitutoyo is a great brand despite this one issue.

As always mitutoyo makes in my honest opinion, the greatest micrometers for the money. If you’re looking for high quality at a reasonable price, you can’t go wrong with these.
