Tungsten carbide milling teeth must be changed frequently because they sometimes last only 1 or 2 days. Diamond-enhanced milling teeth have been developed as a more durable alternative. The durability of tungsten carbide milling teeth was compared with that of diamond-enhanced milling teeth, and the effect of tooth type on fuel efficiency and machine vibrations was measured. In the tests conducted, on average, the diamond-enhanced milling teeth lasted 40 times longer, improved fuel consumption by 14.3% and 29.9%, and reduced the maximum vibration in a milling machine 79% over tungsten carbide milling teeth.
