Because 0.5 lead is so common, you will have plenty of selection in styles of mechanical pencils.Īs with other pencils, mechanical pencil leads may have a lead grade, represented by letters “H” and “B.” H is harder and lighter while B is softer and darker HB2 is right in the middle of this scale. Some people prefer an 0.7 lead for shading and non-detailed work, though. These produce fine, narrow lines, so artists like using them to create details. The standard size is 0.5mm, which is used almost universally in technical drawings. 0.5 and 0.7 millimeter leads are the most common ones they’re still precise but more durable than thinner leads. Smaller diameters work well for fine details and tiny writing but break easily. The smaller the number, the thinner the lead. Lead sizes refer to the diameter measured in millimeters (mm). The pencils are also sold in various styles and materials and look and feel more professional look for ones with built-in erasers, which may often also be refilled.Īs for the graphite refills, you’ll want to understand the different sizes that they are sold in. People prefer mechanical pencils over regular ones because they never have to be sharpened, offer consistent balance and line width, and come in different densities. ![]() This graphite has clay mixed into it to form the pencil lead with which we’re all familiar. It is actually made from a form of carbon called graphite. This has caused the lead inside the pencil to shatter into pieces, it does not need to have been dropped from a great height or with exceptional force. The name is deceptive, because pencil “lead” is not made of the real thing. The first possible cause for a pencil lead breaking easily is that at some point in its life the pencil has been dropped. ![]() If you’re worried about lead in pencils, there is absolutely no reason for concern. If you’re replacing an old refill, first turn the pencil upside down after you open it up and tap gently to get the debris out. The best 0.7 mm pencil lead is made by Faber-Castell, Pilot, Pentel, Uni, and Staedtler. Screw the top back on, and apply pressure to the pencil’s button or other mechanisms (some of them twist) to advance the lead down to the tip. Pentel AIN STEIN is the best premium 2/HB mechanical pencil lead, and the best for 2 lead refills for everyday writing is Pentel Super High Polymer Lead. pencil lead - mixture of graphite with clay in different degrees of hardness the marking substance in a pencil lead lead pencil - pencil that has. To put one in, you usually unscrew the top part of the pencil and insert a fresh piece in the cartridge if it has one otherwise, you’ll drop the in the lead in another way. Mechanical pencils use slim, long pieces of graphite lead that you can replace once you use them up.
