We found Terra Teeth to be extraordinary in terms of penetration and their ability to self feed composite material into the bucket. The unique design allows for quick and deep penetration even in the most abrasive of environments. We use Terra teeth in some of our most abrasive settings including Copper and Silver mines. Even in these abrasive environments Terra Teeth last approximately 3X-4X longer than aftermarket teeth and 2X longer than major OEM teeth we have in use. Effectively, we are doubling and in some cases quadrupling utilization for a given set of teeth. To date we have not found a tooth system to match this type of performance . -- Kevin Stanton, BHP Bilton
