A 90-degree bevelled edge engineers square (100mm x 150mm) is a high-precision layout and inspection tool designed for metalworking, machining, and strict workshop applications.
Key Technical Features

Bevelled Knife Edges: Features two ground, micro-lapped knife-edge profiles on the inside and outside of the blade. This reduces the contact line with your workpiece to a bare minimum, enabling highly accurate visual inspection via the "light gap" method.

High Precision Standard: Typically manufactured to DIN 875 Grade 0 or Grade 00 standards. This guarantees exceptional perpendicularity, parallelism, and flat straightness tolerances across the entire 150mm length.

Inside Corner Notch: Built with an anti-dust relief notch milled directly into the interior vertex. This prevents small burrs, metal particles, or dust accumulation from interfering with your reference angle readings.

Industrial Construction: Machined from hardened stainless steel or heavy-duty tool steel. It provides maximum wear resistance and dimensional stability against temperature fluctuations in demanding environments

The term DIN 8758/0 refers to a high-precision engineers' square (often called a flat angle) that meets the DIN 875 manufacturing standard with a Grade 0 tolerance.

It is used by machinists, toolmakers, and engineers for highly accurate layout, calibration, and inspection of 90-degree angles.

Breaking Down the CodeDIN 875:
The German Institute for Standardization (Deutsches Institut für Normung) specification for steel squares./0 (Grade 0): The highest standard of accuracy commonly available for workshop and metrology use. It guarantees ultra-tight tolerances for flatness, parallelism, and right-angle accuracy
