Tercel air circulation bits are manufactured with jet circulation that directs a stream of air for optimum bottom hole cleaning.
The cutting structure is engineered to meet the most extreme drilling conditions. The bearing design provides balanced load distribution, while the shirt tail protection with tungsten carbide hard-facing provides superior abrasion resistance.
