Lead core

To choose the right lead, check the diameter and hardness that are compatible with your tool. Common diameters include 0.5 mm, 0.7 mm, and 0.9 mm, with hardness levels like HB and 2B. In this selection, you’ll find sets like 20 HB leads at 0.5 mm, as well as bundles that include different hardness levels. Also make sure the lead type matches your intended use—whether you want smooth writing or precise technical drawing.

For everyday writing, HB or B hardness with a 0.7 mm diameter provides smooth, durable lines without much effort. For technical drawing or fine lines, choose 0.5 mm or 0.7 mm with a harder hardness like HB to get crisp, repeatable strokes. Various packs in this range cover HB and B across 0.5 to 0.9 mm, letting you match the lead to your writing or drawing preferences.

To prevent breakage, gently remove the used lead without forcing it, then insert the new lead correctly into the lead holder. Use leads with the same diameter and make sure the lead holder opening isn’t damaged. Gentle handling and proper storage reduce the risk of breakage during insertion and while using the pencil. Keep leads in their original packaging until you’re ready to test them to avoid damage during storage.

Several brands offer leads for lead holders, including MG, Ingco, MG Chenguang, and Pentel, with diameters ranging from 0.5 mm to 0.9 mm. You’ll find HB and B leads, along with options like 0.5 mm and 0.7 mm in packs such as 12 or 20 leads per package. This variety lets you choose leads suited for everyday use, technical drawing, or artistic sketching depending on your preferences.

Packs vary by brand and diameter. For example, one package may include 20 HB sticks at 0.5 mm, while other sets offer 12 or 20 leads at 0.7 mm or 0.9 mm, sometimes with labels like HB or 2B. This variety helps you build a personal kit for your desk or workshop without having to buy repeatedly. Check the exact format on the product label to choose what best fits your tool.

Store leads in their original packaging and keep them at room temperature to avoid fragility. Use a clean lead holder and make sure the lead sticks don’t bend during insertion. Avoid applying too much pressure while writing or drawing, as that can cause breakage. If a lead breaks, remove it and replace it with a lead of the same diameter and hardness to maintain a consistent writing experience.
