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.

Bohler Top             

Body: 45 HRC
Edge: 45 HRC
Thicknesses: 1.5 / 2 / 3 / 4
Heights (Based on Thickness): .865 – 3.937

Description

Top cutting rule offers good bendability, and the body-edge hardness is well balanced for cutting abrasive materials, e.g. solid boxboard, corrugated board, labels, postcards, …

• Through Hardened – Medium Hard
• Low – Medium volume runs
• Cost effective all-purpose rule
• Ideal for paperboard, boxboard, and corrugated
• Similar rules include; Viking MM44 and Helmold H65
