An auger head uses...

Explanation:
Teeth on an auger head must balance hardness and toughness to resist wear and shocks. The best design uses a tough, ductile base with a very hard, wear-resistant surface. Tungsten facing provides that hard, wear-resistant tip, while the forged steel body supplies strength and the ability to absorb impacts without cracking. This combination extends tooth life in abrasive soils and through occasional hard inclusions. Carbide teeth can crack under impact, high-speed steel wears faster in abrasive conditions, and plastic teeth wouldn’t withstand the stresses.
