6-inch Outside Digital Caliper - Outer Diameter Caliper

This Digital outside caliper measures spans up to 6". It has a curved slide clamp so you can fix it to the dimension you need. Whether you prefer to think in Imperial inches or metrics, one touch of a button allows you to switch between the two systems. The on/off button has a zero set button for calibration. This instrument is ideal for lathe turning to help maintain wall spans of hollow projects or determine internal tapers. When chiseling mortises or other joints it helps you keep track of external accuracy.
