1.HA series bit adopts rubber seal with journal bearing, which can suitable higher WOB under normal rotary speed and is suitable for drilling in formations from very soft to middle hard by properly selecting different cutting structure. Hardfaced head bearing surface. Inner hole of cone is silver-plated. And seal structure and lubrication system .O ring seal is made of the more wear resistant and high saturated buna-N with the increased seal section and precisely designed sealing flange in the cone sealing area ha increased the reliability of seal.
High wear resistance and excellent cutting ability of the insert bit are given full play by using carbide compacts of high strength and high toughness in combination with optimized compact numbers an rows, the exposure height and special shaped compacts.
2.Applicable strata: Soft formations with low compressive strength and high drillability such as mudstone, gypsum, salt, soft shale, soft limestone.
