三牙轮钻头型号有：HJ系列，HA系列，GJ系列，GA系列，SH系列，SJ系列，LHA系列，LHJ系列，YC系列，YA系列。
(1) HJ系列是适合直井、定向井的高可靠性钻头。该系列钻头在继承常规HJ系列钻头优越的轴承品质的同时，调整切削结构、合金齿齿材和钢齿敷焊材料，提高了钻头适应各种复杂地层的能力，充分体现常规产品恒久魅力。HJ系列钻头适应240～40rpm转速钻进，是直井、定向井和探井钻进理想选择。
(2) GJ系列钻头为金属密封滚动轴承，能够稳定在中低钻压、中高转速下钻进，是上部井段的理想选择。镶齿钻头可选偏顶勺形齿、勺形齿、楔形齿和锥球齿等多种高效合金齿。钢齿钻头增加敷焊层厚度和齿的露高。该系列钻头配置了多种可选特征，提高了适应不同钻井工艺和各种复杂地层的能力。
(3) HA系列钻头为橡胶密封滑动轴承，在常规转速下使用可承受较高的钻压，配合不同的切削结构，可以适应极软到极硬地层。镶齿钻头采用高强度高韧性合金齿，充分发挥了镶齿钻头高耐磨性和优异切削能力。钢齿钻头齿面敷焊新型耐磨材料，延长了钻头使用寿命。
(4) GA系列为橡胶密封滚动轴承钻头，对于中低钻压的较高转速钻井，它是理想而又经济的工具。
(5) YC单牙轮钻头牙轮顶部采用金刚石复合齿，增强牙齿的耐磨性，提高钻头使用寿命。新型水力结构提高了水力系统对牙轮和井底的清洗能力，优化井底流场。钻头体保径齿选用大直径的主动切削保径球头齿，使钻头具有良好的保径作用和倒划眼功能。该系列钻头适合老井开窗侧钻和老井加深等小井眼钻井作业。
(6) SKH系列钻头采用橡胶密封浮动轴承和具有超强攻击性的切削结构，具有进尺高和机械钻速快等特点，是上部均质地层的理想选择。PDC钻头型号有:SX1941X,SX1943,SX1954,SX1956,SX1963S,SX1966等
