Definition & Meaning of "drafting pencil"

What is a "drafting pencil"?

A drafting pencil is a tool designed for precise and fine-line drawing in technical work such as drafting, sketching, and illustration. It typically has a thin, hard lead that produces sharp, clean lines without smudging, making it ideal for detailed drawings. Drafting pencils are often mechanical, allowing for easy lead replacement and consistent line thickness. The lead is usually marked with hardness levels, ranging from H, which is hard, to 9H, which is very hard, with harder leads being used for finer lines. These pencils are essential for professionals like architects, engineers, and designers who require accuracy and detail in their work.
