Rotring Polymer Leads 0.5 HB are high-polymer 0.5 mm leads designed for consistent, smooth writing and precise technical drawing. The HB hardness balances darkness and strength, while the durable polymer composition reduces breakage and ensures even lines. These refill leads are compatible with most 0.5 mm mechanical pencils and come from the Rotring brand, known for tools for technical and everyday use.

Advantages

The fine 0.5 mm diameter provides accurate line control for detailed work. The HB grade offers a middle ground between hard and soft leads, suitable for clear, readable lines and moderate erasing. The polymer formula increases resistance to snapping, delivering longer-lasting performance and consistent line quality throughout use.

Suitable for

  • Technical drawing and drafting
  • Everyday writing and note-taking
  • Sketching and preliminary artwork
  • Students and office use

How to use

Insert the 0.5 mm Rotring polymer lead into any compatible 0.5 mm mechanical pencil according to the pencil manufacturer's refill instructions.

Recommendations

For best results in technical drawing, use in a stable mechanical pencil with a fixed sleeve or a retractable sleeve to protect the lead tip. Store the leads in a dry place and avoid dropping the refill container to minimize accidental breakage.
