HB 0.7 mm KOH-I-NOOR Leads – Versatility and Reliability

Product: Graphite leads for mechanical pencils
Hardness: HB (Medium)
Thickness: 0.7 mm

When choosing leads for a mechanical pencil, it's not just the thickness that matters, but the quality of the graphite composition. The KOH-I-NOOR 4162 series leads are a gold standard both in schools and offices. We tested these 0.7 mm HB leads and provide a professional insight.

1. Writing Quality and HB Hardness

The HB (Hard-Black) hardness class is the most versatile. These leads ensure a perfect balance between line clarity and graphite consumption. During testing, we noted:

• Gliding: The graphite glides easily across the paper surface without leaving scratches, which is common with cheaper alternatives.
• Durability: The 0.7 mm thickness is slightly sturdier than the standard 0.5 mm version, so these leads break much less often, even with stronger pressure.
• Erasability: These leads erase easily using a standard eraser, leaving no smudges or shadows on the paper.

2. Precision and Application

While 0.5 mm leads are often used for ultra-fine details, the 0.7 mm line thickness is ideal for those who appreciate a bolder and clearer line. It is an excellent choice for daily writing, note-taking, or initial sketching. Since the lead length is 60 mm, a single lead lasts a long time even during intensive work.

3. Packaging and Convenience

The leads are packed in a compact plastic case containing 12 pieces. This ensures that the leads do not break while stored in a pencil case or drawer, and the convenient dispensing opening allows for safe and quick refilling of the mechanical pencil.

Frequently Asked Questions (FAQ)

Do these leads fit a 0.5 mm pencil?

No, these leads are 0.7 mm thick, so they only fit mechanical pencils specifically designed for 0.7 mm leads.

What is the difference between HB and 2B?

HB is medium hardness. 2B is softer, writes darker and bolder, but wears down faster and smudges more easily.
