Mitutoyo is an obvious choice when selecting metric dial indicators. They are reliable and affordable. Spare parts are also available should you ever need to make a minor repair (new contact points, new bezel and crystal, new locking screw, for example.)
The bezel diameter is about 2-1/4" (57 mm). The mounting stem is a regulation 8 mm in diameter on white dial models. A yellow dial will indicate that it has a 3/8" diameter stem. It comes complete with lug back for secure fastening to magnetic stands, granite stands and fixtures.
It features a new Mitutoyo innovation: two dovetails are integral with the outside of the metal case to which you can easily clamp any dovetail accessory, including the bezel clamp (included). If you want, the indicator can now be mounted to a stand or fixture directly from the case rather than the back or the stem. Tolerance markers are included with this model.
Made in Japan. When buying from an authorized Mitutoyo distributor, you are guaranteed to get a genuine Mitutoyo indicator, not one of the Chinese rip-offs which have recently flooded the markets at not-surprisingly cheap prices. If buying from Amazon look for the wording "ships from and sold by Amazon.com"
Idea: add a magnetic base stand to hold your dial indicator. An ideal combination for the shop and automotive work.
Do you need to go deeper than 1"? Use contact point extensions with your dial indicator. These will not increase the amount of travel, but they will extend the reach. See page 133.
