Precision straight edge, burnished steel 750mm in imitation leather case
Precise measurement and control of flatness
The precision-manufactured straight edge made of hardened steel is ideal for checking the evenness of a wide variety of surfaces. With a length of 750 mm and tested accuracy in accordance with din 874 sheet 2, it enables precise checking of straightness using the light gap method. Perfect for use in workshops, laboratories or quality control, this straight edge offers maximum precision and reliability.
Excellent workmanship for maximum accuracy
The test edge of the straight edge has been carefully lapped to provide a particularly slim edge that makes the light gap optimally visible. Straightness in the swivel range of ±20° is guaranteed, which means that this ruler ensures precise control even in demanding applications. The burnished surface of the alloyed case-hardened steel ensures a particularly glare-free and durable design.
Ergonomic design for comfortable handling
In addition to technical precision, the straight edge also offers well thought-out ergonomic features. The hand heat protection on the back has been designed so that it can be used as a storage surface. This increases comfort during use and prevents unintentional heating through hand contact.
High-quality materials for a long service life
Made from alloyed and stainless tool steel, which has been hardened to a hardness of hrc 60, this straight edge not only offers precision, but also a long service life. The robust steel has also been stress-relieved to prevent deformation and the surface has a non-glare matt finish, making it easier to use in a wide range of lighting conditions.
Optimale storage and protection
To protect the precise tool, the straightedge is supplied in a high-quality imitation leather case. This keeps it safe from damage even when not in use and allows it to be stored clean and dust-free. The practical case also enables safe transportation.
