Rotring Polymer Leads 0.7 B (S0312680) are high-polymer fine leads designed for smooth writing and precise lines. With a B softness grade and 0.7 mm diameter, these leads provide consistent, dark strokes and good break resistance, suitable for technical drawing, sketching and everyday writing tasks.

Advantages

The polymer composition delivers clear, uniform marks on paper while reducing crumbling. The B hardness produces darker lines than HB, making these leads well suited for shading and visible technical lines. Their extra-strong formula improves break resistance, extending the usable life of each refill and reducing interruptions during work.

Suitable for

  • Technical drawings and drafting
  • Sketching and illustration
  • Everyday writing and note-taking
  • Architectural and engineering sketches

How to use

Load the 0.7 mm polymer lead into a compatible mechanical pencil according to the pencil manufacturer's instructions. Use standard advance mechanism to extend the lead as needed. Replace the lead when writing becomes faint or the tip wears down; store spare leads in their container to protect them from breakage.

Recommendations

For best results use with mechanical pencils specified for 0.7 mm leads and avoid excessive side pressure to minimize the risk of lead breakage. Keep spare leads in a stable container to prevent chipping.
