Spacer Rule – Bohler, Viking, Helmold

Through-hardened rules have the same hardness in body and edge. A specific tempering and decarburization process achieves a specific rule structure with a soft deep decarburization zone, which results in excellent bending properties. In general, Bohler, Viking, and Helmold cutting edges and bevels have a shaved finish for highest accuracy.
