Made in France for Lee Valley, these steel calipers and dividers all have ground tips. The divider tips are hardened for scribing on metal. All fittings are solid brass.
Particularly useful is the quick-adjust mechanism that incorporates a sliding speed nut. The nut engages only when it comes up against the centering collar next to the leg post. The strong spring holds any setting accurately. Black oxide finish.
Sizes indicated are maximum opening. The 4" is ideal for finer turning; the 8" size for general-purpose use; and the 12" for large work. Calipers and dividers are also available individually.
