The Caran d'Ache Technograph 2mm 4H replacement leads are designed for professionals, architects, and students who require exceptional precision and clean, low-smudge line work in their technical drawings and drafting projects. These Swiss-made leads offer a superior, extra-hard graphite consistency that maintains a sharp point for extended periods, though users should be aware that the 4H hardness level produces very light lines that may be difficult to erase completely if pressed too hard.

4H stands for the hardness grade of the graphite. It is on the harder end of the scale, meaning it produces a lighter, finer line that stays sharp longer than B or HB grades.
Yes, these are standard 2mm leads compatible with almost all universal 2mm clutch and lead holder pencils.
Due to their hardness, 4H leads are designed for light lines. While they can be erased, applying excessive pressure can leave indentations in the paper that cannot be removed.
Each pack contains 3 individual 2mm graphite leads.
No, the 4H grade is specifically formulated for light, fine lines and is not suitable for shading or dark artistic work.
Clean the clutch jaws with a dry cloth to remove any graphite dust that may be preventing a firm grip.
Check your lead pointer to ensure it is not dull, and reduce pressure on the paper as 4H lead is intended for light, precise strokes.
To install these leads, ensure your 2mm clutch pencil mechanism is clear of any broken graphite shards. Gently depress the cap or button to open the clutch jaws and insert the lead from the front.
