Differences In Precision Measuring Tools



The shops use a variety of different tools for projects. And we've gone over the basic tools from wrenches to hammers however, we haven't taken a look at one group: precision measuring tools. They're used for building engines or setting up rear ends.

There are the basics: micrometers, digital calipers, dial calipers, and dial indicators. First up is the dial indicator. It measures in thousandths of an inch and has several adjustments which make it great for measuring backlash on a rear end or end play for a crankshaft on engine builds.

Dial calipers are similar to the dial indicator. By using the jaws you can measure either outside or inside diameter. Digital calipers measure the same thing but give a digital reading.

Micrometers also measure outside diameter but give a bit more precise reading.
