Description

Scribers are made from a rod of Hardened and Tempered Tool Steel which has been ground to a fine point at one or both ends. They are used to mark accurate lines - usually when working in metal.


Features and Applications

Scribers are sharpened to a 30 degree point by holding them Tangentially to a Tool Grinder and rotating them. This tends to create grinding marks which run along the point and strengthen it rather than weakening it by going across.


Note: When scribing lines for bending or folding sheet metal (or plastics) always mark on the surface that will become the inside of the bend. In this way, Compressive Forces will close up the scribed line during bending, whereas if on the outside, Tensile Forces would open it up and may cause the material to tear or fracture.


Note: To make scribed lines stand out more, bright steel can be coated with Marking Blue (or a felt tipped pen) whilst black steel or rusty metal can first be rubbed with chalk.
