Hard graphite leads

Choose leads by matching the pencil diameter, the hardness you prefer, and the length that fits your pen. In this range you’ll find 0.5 mm and 0.9 mm leads, with hardness grades like HB, 2B, and B. For example, 12 leads per pack at 6 cm length are available in HB 0.9 mixes, while others show 0.5 mm HB or 0.9 mm 2B options. Consider your typical writing—lighter notes benefit from HB, while darker lines come from 2B or B grades.

Lead hardness indicates how dark the writing appears and how much it wears down with use. HB sits in the middle, offering balanced darkness and durability, ideal for everyday notes. Softer leads like 2B produce darker lines but smear more easily, while stiffer leads (H-range) give lighter marks and longer wear cleanly. The catalog includes mixed packs labeled HB 0.9, 0.5 HB, or 2B variants, so you can tailor your choice to your usual cadence and the type of paper you work with.

Students typically prefer 0.5 mm leads for neat, precise lines in classrooms, while professionals doing drafting or detailed annotation may lean toward 0.9 mm for stronger lines and fewer interruptions from lead breakage. Packs commonly contain 12 leads, with several products specifying 6 cm length to fit standard mechanical pencils. Examples include 0.5 mm HB leads and 0.9 mm HB or 2B options, ensuring you can pick a size and hardness that matches your writing tasks.

Store leads in a dry, cool place and avoid exposing them to humidity, which can dull the edges. Use the correct diameter for your pencil to prevent bending or jamming; 6 cm long leads are standard here and fit most mechanical pencils designed for that length. Handling with care helps maintain compatibility across brands like Pilot, Pentel, and Stabilo, and reduces breakage when inserting or advancing the lead during writing.

You’ll find popular brands such as Pilot, Pentel, and Stabilo offering a range of mechanical-pencil leads. Available varieties include ENO G 0.9 HB packs, HI-POLYMER 0.5 HB options, and 0.9 B or 2B strengths. Lead lengths are consistently 6 cm, and most packs include 12 leads, though some sets specify 20. This diversity lets you mix and match hardness and thickness to suit writing, drawing, or precise drafting needs.

Yes, these leads are designed to fit most standard mechanical pencils that accept 0.5 mm or 0.9 mm leads and use 6 cm long refills. Always verify your pencil’s accepted diameter before purchasing, as compatibility depends on the lead size. The range includes several 6 cm, 12-lead packs across different hardness grades, so you can easily replace spent leads without altering your usual writing experience.
