Tungsten Carbide vs. Cobalt Drill Bits

At 82 HRC, give or take, tungsten carbide is much harder than cobalt or HSS. This is carbide's only Achilles' heel—where cobalt will flex a fair amount in the face of radial cutting forces, carbide will in many cases shatter. This means that proper alignment is critical for tool life and hole accuracy (which is true of any drilling ...

Is Tungsten Magnetic? (No. It's Not)

Yes, tungsten carbide is magnetic. This is because it generally uses cobalt or nickel as a binder, both of which are ferromagnetic metals, and they impart their magnetic properties to the alloy. Tungsten carbide is a carbide (a kind of chemical compound) containing equal parts of tungsten and carbon atoms. In its basic form, tungsten carbide is ...
