 特性及應用 Features and Application                        

1、淺拋物線、弧形五刀翼冠形和高密度布齒設計適合中硬到極硬地層；

Five arc blades, lower parabolic profile and very heavy cutter density are designed for medium hard to extremely hard formation;

2、使用不同專利技術的復合片提高了鉆頭鉆進硬夾層的能力。

The layout of different patented PDC cutters enhances the capability of drilling hard stringers.
