| are applied when a higher hardness of cutting edge is required, i.e. when cutting abrasive materials and with large series productions. This type of rule combines a softer rule body resulting in better bending properties, with a harder cutting edge thus prolonging the service life. |
indicate excellent bending abilities. The cutting edge has a smoother surface compared to rules with a ground finish, thus reducing the formation of dust during operation. Exacting height tolerances shorten the set-up time and prolonge the service life of the rules. |
