🔧 What it does & how to use

A divider caliper is a bench essential for jewellers, watchmakers and metal workers, used for marking out, transferring measurements and scribing circles or arcs directly onto a workpiece. The hardened tips hold a sharp point for clean, accurate lines, while the thread adjustment nut lets you lock in an exact span and keep it steady through repeated use.

• Set the span: Open the legs to the required measurement using a rule or gauge, then tighten the thread nut to lock the setting.
• Mark a point or line: Rest one tip on your reference point and drag the other tip lightly across the material to scribe a straight line.
• Scribe a circle or arc: Plant one leg as the centre point and swing the other leg round to score a clean, consistent circle.
• Transfer measurements: Use the fixed span to step off or copy distances between components without needing to re-measure each time.
• Re-check the setting: Periodically confirm the span hasn't drifted, especially before repeating a measurement across multiple pieces.
