Collection: Mechanical Drawing Pencils
Diameter is the number that matters and it decides everything afterwards, because a lead sized for one barrel will not feed in another and a mixed drawer becomes useless. Finer leads suit technical work and snap under pressure; thicker leads take shading and survive a schoolbag. Grade still applies on top of that. Check the barrel before ordering a tube of refills. See pencil leads, drawing pencils and erasers.
