I don't quite understand what you mean by HB-2 pencil but if you mean HB pencil / #2 Pencil it is not the softest pencil. Pencils scale from 9H to 9B, (HB in the middle) and 9B would the softest and darkest pencil there.
If your asking if the pencil has Lead, then the answer is that most pencils do NOT have lead in them anymore.
A 7mm pencil lead is thicker than a 5mm pencil lead. The diameter of the lead determines its thickness, so the lead with a larger diameter will be thicker.
Graphite is the mineral that is used to make the lead in a pencil. Despite its name, pencil "lead" is actually composed of graphite mixed with clay.
The streak color of pencil lead is typically a shade of grey.
Pencil "lead" is actually made of graphite, which is a form of carbon. The graphite is mixed with clay to give it form and strength. These mixture of graphite and clay are then encased in wood to create a pencil.
There are about 20 grades of pencils from 9H the hardest, to F being the softest

The darkness of pencil lead is determined by its graphite-to-clay ratio. The higher the graphite content, the darker the lead. Therefore, a pencil lead labeled as "HB" or "B" will be darker than a lead labeled as "H" or "F." The darkest pencil lead commonly available is typically labeled as "6B" or "8B," indicating a high graphite concentration.
A typical lead pencil does not actually contain lead. The "lead" in a pencil is made of graphite, which is a crystalline form of carbon. Therefore, there is 0% lead in a lead pencil.
There is no lead in pencil - Pencil is made from graphite
Pencil lead is a compound
It's softer. #1 softest, #2 slightly harder, #3 harder than #2, etc.Softer.a #1 pencil is softer than a#2 pencil
If your asking if the pencil has Lead, then the answer is that most pencils do NOT have lead in them anymore.
Pencil lead isn't really lead, it is graphite, a form of carbon. Pencil lead doesn't have any lead in it whatsoever.
Pencil lead is a conductor.
we get lead of pencil from the mixture of clay and graphite
A 9mm pencil lead is thicker than a 7mm pencil lead.
