Two brass calipers for jewellery and craft

This set supplies a 3.15" and a 3.94" vernier caliper ruler, both machined from solid brass. The non‑magnetic material resists rust and deformation, so the tools stay accurate in workshops, classrooms or field kits. Jewellers, hobbyists and engineers can measure inside and outside diameters of rings, beads and small components without needing separate instruments.

Dual millimetre and inch scales remove conversion

Each caliper carries clear metric and imperial graduations on a single beam, letting the user read either unit directly. The sliding jaw moves smoothly across the 80 mm and 100 mm ranges, giving repeatable results for repetitive layout or inspection tasks. No batteries or electronics are involved, so the tool is always ready when a quick dimension check is needed.

Brass construction stays cool and quiet in hand

The metal body feels neutral to the touch during prolonged use and adds no audible noise beyond the faint slide of the jaw. There are no powered parts, so power draw is zero and no heat builds up in the tool itself. The compact 3.15" and 3.93" lengths slip into a pocket or tool pouch without adding noticeable weight.

Questions about this item

Does the brass construction of the 3.15-inch and 3.94-inch calipers generate heat during extended use?

No, these are passive brass measuring tools with no power source or moving parts that produce heat; they remain at ambient temperature during all-day use.

What additional equipment is required to operate the 80 mm and 100 mm vernier calipers?

None; the calipers are self-contained manual instruments that require only the user's hand to slide the jaw and read the dual-scale markings.

Can the 3.15-inch and 3.93-inch brass calipers measure parts on older machinery with worn surfaces?

Yes, the smooth sliding jaws and clear millimetre and inch graduations allow accurate inside and outside readings on worn or irregular workpieces without electronic interference.
