Using Drafting Pencils, Leadholders, and Mechanical Pencils: For precision in the drawing of lines, the drafting pencils are made in a number of grades. The grades for the graphite (pencil lead) range from hard to soft. In general, hard pencils draw light lines; soft pencils draw darker and wider lines.
The hardest standard grade for drafting/drawing pencils is 9H. The softest pencil is grade 6B. In general, a 4H pencil is used for light layout lines and guide lines that are easy to erase. A sharp H pencil is used for thin dark lines (dimension and extension lines, template work, and lettering). A blunted F pencil is used for thick/dark object lines for walls and borders. Leadholders and mechanical pencils perform the same function as the wooden drafting pencils, but the lead is purchased separately based on the line type needed above. Choose the pencil lead and pencil needed for your application.
