JAM Precision Sine Bar – 100 mm Length – Hardened Steel - Made in Japan
JAM Precision Sine Bar – 100 mm
This JAM Precision Sine Bar is designed for accurate angular setup using gauge blocks. The hardened steel body and precision‑ground faces provide stable, repeatable geometry for grinding, inspection, jig building, and toolmaking.
The compact 100 mm length makes it ideal for tight setups, small fixtures, and surface‑grinder work where a full‑size sine bar is too large. JAM is known for producing reliable Japanese metrology tools with consistent accuracy and workshop durability.
