How it's used
Refers specifically to the thin graphite refills used in mechanical pencils, which are called 鉛芯筆 in Cantonese. While the word contains the character for lead, these refills are made of graphite and clay, not actual lead. It is common to specify the thickness, such as 0.5 or 0.7, when buying them at a stationery shop.

Do not confuse this with 鉛筆, which is the entire pencil itself. Also, ensure you use the correct measure word 支 when talking about individual pieces of lead.
