Core barrel teeth are vital items on drilling tools as they help in improving the cutting efficiency and longevity of rock coring operations. These teeth are typically constructed using high-grade tungsten carbide or alloy steel and provide excellent wear resistance and impact strength, resulting in a long service life even when drilling abrasive formations. 

Core barrel teeth are able to provide accurate core recovery without causing any sample disturbance even when handling very sensitive or delicate cores as compared to the standard bits which makes them ideal for geological surveys, mining industry and oil/gas drilling.
