Cutting Structures Bit performance depends heavily on cutting structure design. Our system allows us to optimize cutting structure designs by using the proper selection and combination of insert shape, projection, diameter, and grade. By selective placement of insert and insert row location, we can modify clearances to make our cutting structures as aggressive or tough as possible
The “Heart” of every rotary product is its bearing. Respecting this concept, Far Eastern Drilling continues to improve bearing designs through exact heat treatment and precise manufacturing processes.
Shirttail designs with specific thickness allow closer placement of carbide inserts to shirttail contours.
