Exactly how thick is this plywood? How wide is the groove cut by that router bit? Is my router bit exactly 1/2" in diameter? Your tape measure doesn't have the answers to these simple questions!
Calipers that read in thousandths of an inch are a smart addition to every workshop for helping you better understand the materials you use and the results of your machine work. When paired with the 0.001" resolution and accuracy of an INCRA LS fence system, a set of calipers is an incredible time saver - measure, cut, done!
At the same time, most woodworkers are more comfortable with fractions. While there are other fractional calipers available, Wixey raises the bar with their exclusive Precise Fraction Technology. These calipers simultaneously display fractions and decimal inch in 1/1000" resolution, and they have metric capability, too. Fractions are only displayed within 0.003" of the fraction's true equivalent, which is far more precise than previous fractional calipers.
Wixey calipers incorporate precision measuring features found in top-of-the-line measuring tools used in metal working, with precision ground measuring faces that allow accurate outside, inside, depth, and step measurements.
