What is Tungsten Carbide?

Tungsten carbide refers to the equal measurement of tungsten with carbon that forms a high-density cutting tool.

It has a natural light gray appearance with bits of a bluish tinge. Tungsten carbide melts without decomposing at 2,000 degrees Celcius.

That means you can comfortably derive shapes from it through a process called sintering by forming or sintering.

Is Tungsten Harder Than Diamond?

Not really.

So far, the diamond appears harder than any other metal we know of. It has extreme hardness and superior strength to perform strongly on all types of materials.

Pencil grinder bits made from diamond have quality cut but with a rough effect on the material surface. Industries that don’t necessarily need smooth material surface can deeply rely on tools made from diamond.

Tungsten carbide is next to diamond in hardness and strength. Thus, you have powerful and durable sharp grinding confidence when handling materials of different nature.

They have strong cutting action, similar to diamond. However, tungsten carbide pencil grinder bits have a better finish in terms of smoothness than diamond.

Diamond pencil grinder bits give a stunning impact strength when applied to the material. Tungsten provides remarkable tensile strength and has a higher melting point.

The nature of your job can determine the type of pencil grinder bits to use.
