What is the softest lead for mechanical pencils?

What is the softest lead for mechanical pencils?

2B, 3B and 4B are increasingly soft. Further up the range, 9B is the very softest lead available, but so soft and crumbly that it's rarely used. Anything over 4B is probably too soft for most people's day-to-day use. Harder leads than HB get H ratings.

Does a mechanical pencil have lead?

A mechanical pencil, also clutch pencil, is a pencil with a replaceable and mechanically extendable solid pigment core called a "lead" /ˈlɛd/. The lead, often made of graphite, is not bonded to the outer casing, and can be mechanically extended as its point is worn away as it is being used.

Is 0.7 lead the same as a #2 pencil?

They are right, that has to do with relative hardness/softness of the pencil. An HB lead is right in between and is considered equivalent to a #2 pencil. About the only time this concerns me is when I take a fill-in-the-bubble test that requires a #2 pencil. An HB works just fine.

How much lead is in a mechanical pencil?

0.7mm is the most common lead size used for mechanical pencils. The writing style matches closely to the size of a fine ballpoint or rollerball, and is available in the widest array of hardnesses.
