HF435LB
5刀翼中抛物线轮廓,非对称刀翼布齿,水力平衡设计,使钻头受力平衡,具有更好的稳定性。主切削齿采用高性能复合片,在确保钻头寿命的同时,提高机械钻速。使钻头在软到中硬地层中具有较高的机械钻速。
钻头适用于软至中硬地层和夹层灰岩。
Five blades parabola Outline, Asymmerical blade tooth arrangement, hydraulic balance degign, Causes the bits stress to be balanced, has a better stability, the main cutting tooth Uses the high performance compostive. While guarantees the drill bit life, it can enhance the drilling fast. Optimizes the compound dew tooth depth, make the bits to have the high the high drilling fast in soft-hard formation. The bits adapt in the soft to the hard formation and the band calcareous rock.
