 ● 镜面黑冰齿减少剪切力。
● 梳状金刚石层延缓切削齿磨损，提高自锐能力。
● 抛物线外形大复合片布齿，适用于软至中软地层。
● 螺纹喷嘴可优化水力参数配置。
● 螺旋翼深水槽有利于排除岩屑
● 聚晶金刚石加强保径，可有效降斜。
● Highly polished cutter surfaces reduce shearforces,cutting removal，ROP and drilling efficiency.
● The different layout of PDC cutters makes bit more attack,and extend bit life.
● Deep blade configuration makes possible high rates of penetration in soft formations and effective cooling in harder,more abrasive formations.
● Suitable for soft to medium soft formations.
