Product Overview
HAT series bit adopts rubber seal with journal
bearing, which can sustain 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.
Main structure features
1.Journal bearing. Hardfaced head bearing surface. Inner hole of cone is silver-plated. The load capacity and seizure resistance of the bearing is greatly improved.
O ring seal is made of the more wear resistance high saturated buna-N with the increased seal section and precisely designed sealing flange in the cone sealing area increased the reliability of the seal.
2.All rubber compensator is used which can limit pressure differential and prevent drilling fluid from entering the lubrication system and this provides the bearing system with good assurance of lubrication.
3.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 and rows, he exposure height and special shaped compacts. For steel tooth bit the tooth surface is hardface with new type of wear resistant material and thus extended working life of the cutting structure while still maintaining high ROP.
4.A row of inserts is added between gauge row and heel row of HA bit to trim borehole wall and protect cone shell and
consequently, the special HAT series bit is formed.

Application
Application to oil well ,gas well, Construction, Water Drilling, Mining, Horizontal Directional Drilling, Geothermal and Environ-mental.
Tricone bits are used in general to drill a wide variety of rocks, from soft to extremely hard, while PDC bits can drill various
sorts of formations, especially at harsh environments.
This is just part of the content. Do you want to know more about it? Please contact our customer service, tell your needs, you will hear the most professional reply!Please select the applicable formation and parameters according to the instructions.
Carefully check the bits appearance and to check the bits threaded end face,whether the serial number on the box and certificate.
Selection of WOB and RPM should be within the limits of the recommended parameters, higher WOB and RPM cannot be used simultaneously. Bottom hole must be clean and bit must not be used for long section reaming. Drilling process must operate smoothly, find that there is Bie jump on abnormal phenomenon, should be timely analysis and take effective measures The bit should be kept indoor with dry and well ventilated conditions at 10-33℃ and kept from sunshine and rain. Stored under such conditions, quality of bit is guaranteed for 3 years.
