FAQ Lead for Lyra Dry Profi Giant 331 10H graphite stonemason (pack of 12) LYRL4479120
- What is the primary application for this 10H lead?
- The 10H hardness is specifically designed for marking on rough construction materials such as brick or concrete. This lead offers excellent wear resistance, ensuring optimal durability of the mark on abrasive surfaces.
- Is this lead compatible with other mechanical pencils?
- This reference is exclusively sized for the LYRA Dry Profi Giant 331 mechanical pencil. It must not be used in standard mechanical pencils with a smaller diameter, as it will not fit the specific clamping mechanism of this professional tool.
- How can I ensure the longevity of the lead during marking?
- To prevent breakage when marking on very hard materials, it is recommended to maintain moderate and constant pressure. Ensure that the length of the lead extended is minimal to reduce the overhang and optimise rigidity during use.
