The Mitutoyo 103 series outside micrometer has a vernier scale in metric units for taking precise outside diameter (OD) measurements, and a ratchet-stop mechanism for uniform pressure during adjustment. The micrometer’s frame has a baked enamel finish for protection and durability. The vernier scale on the thimble and sleeve is graduated to 0.01mm, with a satin chrome rust- and glare-resistant finish. The spindle and anvil have flat measuring faces and are carbide-tipped for wear resistance. A spindle lock helps provide secure locking of the measurement position.
Micrometers are precision measuring instruments that use a calibrated screw to measure small distances. These measurements are translated into large rotations of the screw that are then able to be read from a scale or a dial. Micrometers are typically used in manufacturing, machining, and mechanical engineering. There are three types of micrometer: outside, inside, and depth. Outside micrometers may also be called micrometer calipers, and are used to measure the length, width, or outside diameter of an object. Inside micrometers are typically used to measure interior diameter, as in a hole. Depth micrometers measure the height, or depth, of any shape that has a step, groove, or slot.
Mitutoyo manufactures precision measuring tools, metrology equipment, and systems. The company was founded in Tokyo in 1934 and formed Mitutoyo America Corporation in 1963, which is headquartered in Aurora, IL.

Purchased this for measuring valve shims. I confirmed accuracy by measuring new out-of-the-box shims and found it both accurate and easy to use.

With only one picture and multiple descriptions, I was skeptical about getting what I needed and a Mitutoyo micrometer for $43? The delivered product was exactly what I needed and appears to be of great quality. I am not building a spacecraft, just some engine work and this definitely fits my needs. Read the description for size and accuracy when you order and that is what shows up. I was so happy I ordered a second micrometer.

I'm not a professional machinist but I believe this micrometer was an excellent value for the money. No complaints.

I looked at cheap alternatives, but all appeared to be "Hit and Miss: with some negative reviews.After visibly inspecting this Mitutoyo 25-50mm Micrometer, I am more than happy that I did not order any of them.Appearance seems to live up to the Mitutoyo name. I won't be using this for a while but from a brief inspection it has a very smooth action and ratchet, and Zeros out almost perfectly with the set piece. I also compared the accuracy against a Mitutoyo Absolute Digital Vernier caliper - while these can be accurate, they can be so accurate as to not always exactly repeat, depending at what angle it is held. However, the difference between the two was only the thickness of a line on the Micrometer barrel.

This seems like a nice Micrometer, especially for the price, but I have very high expectations for Mitutoyo based on the past, and minor finish issues with the one I received make we wonder whether it is truly a legitimate Mitutoyo or whether their quality standards have dropped.

Received today, I inspected the instrument and all is perfect!Maybe tomorrow I will start working with it to adjust my motorcycle valve shims clearance and I will post later the results.

You cant find anything like this its precise and great quality, i wish it had a better box. Digitals can get problems and dont believe they are durable enough.this is good enough and 0.001mm resolution

I’ve always been a calipers guy but a good pair of mic’s changed that. These Mitutoyo mic’s are them, not only are they well know for their quality and precise tools they also had metric versions

I have oedered this as my new lathe is metric and my other micrometer is imperialand making parts to repair a few long case clocks all good so far.

Equipo muy util para taller, y para trabajos de aficionados con pequeñas maquinas herramienta; Mejora mucho la repetitividad de medidas, y precisión, frente al uso de un calibre tradicional; se garantizan trabajos con una precision de la centesima de milímetro.El micrometro de Mitutoyo es perfecto, y da lo que anuncia: preción al nivel definido en todo el rango de medida.Vale la pena la diferencia de precio sobre otros micrometros que aparentan precisión que luego no cumplen ni por repetitividad de medida, ni por homogeneidad de la precisión en el rango de medida.¡Cuidado con las falsificaciones!, estos equipos solo se venden a su precio normal; Vendidos desde China a valores de su mitad de precio son falsificaciones. Los precios de referencia en la pagina web de Mitutoyo en Europa.

I have always bought Mitutoyo micrometers for the sheer quality of them. I’m yet to be disappointed by them

This micrometer does exactly what it's meant to do i have other micrometers which I have had for many years and this one fills a measurement gap I do not use micrometers very often I use calipers the mitutoyo is a quality item
