Mantle 2016 Series

Description
The interface between the diamond layer and the cemented carbide substrate of a Mantle series PDC comes with an arch face with a drip streamlined convex structure. With a unique design, the series minimizes the residual stress at the interface, for which the company was granted a utility model patent (patent No.: ZL201310635074.8) in 2015. The series is a total improvement in terms of manufacturing processes; with the impact resistance (local or global) at the diamond layer greatly enhanced, it is the product series with the best impact resistance among the HMR products. Another outstanding feature of this series is its continuous wear resistance – it remains highly wear-resistant at the later stage of its lifecycle, making it extremely suitable for drilling tough strata in the land or ocean.
