🔧 What it does & how to use

A divider caliper is a bench essential for jewellers, watchmakers, clockmakers and metal workers who need to scribe accurate circles, arcs or straight reference lines, or to step off and transfer measurements between parts. The threaded adjustment nut lets you lock the legs at a precise, repeatable span, and the hardened tips hold their point through repeated use.

• Set the span: Open the legs to the required measurement using a rule or gauge as a reference.
• Lock the setting: Turn the thread adjustment nut to fix the legs firmly at that span.
• Mark the workpiece: Rest one point on the metal or dial surface as a pivot and swing the other point to scribe the circle or arc.
• Transfer measurements: Use the fixed span to step off equal distances or copy a measurement from one part to another.
• Fine-tune as needed: Loosen the nut slightly to make small adjustments, then re-lock before continuing work.
