Commonly called scribing compasses, dividers have two legs with sharpened points for marking arcs or circles on the surface of a workpiece. One leg of the divider sits in a dimple created in the workpiece surface, while the other leg turns around that leg and presses against the material to create a mark. These tools are most frequently used in metalworking and drafting applications.
Take quick measurements of hard-to-measure dimensions or of long distances. Similar to a compass, spring calipers use two spring-loaded adjustable legs for measuring. Simply adjust the legs to the size of the dimension being measured, then check the caliper on a ruler or other measuring tool.
Instead of a spring, these tools have a screw and nut for more precise positioning.
Consisting of one caliper leg and one divider leg, these tools allow one leg to reach around the edge of the workpiece.
