Productintroduction：H系列钻头为O形橡胶密封滑动bearingdrill，钻床可以在常规的速度承受更高。 该mainstructure特点：

1.采用高强度和高韧性硬质合金齿，从而提高theability抵抗冲击的牙齿，减少齿破碎率;

2.牙排数，齿数，齿高和独特的alloytooth造型Optimizationdesign充分发挥了钻头切削和切割速度;

3.使用circliplocking锥，可承受高压力;

4. Antifrictionalloy内孔焊接增加轴承的抗惊厥能力;

5.使用highsaturation丁腈橡胶O形 - 环andTricone bitseal压缩优化提高了可靠性ofbearing密封;

6.使用limitpressure和防止橡胶管钻井液进入lubricationsystem，其提供良好的润滑的轴承系统，并确保thatthe O形圈的正常工作和提高钻头的工作寿命;

7.使用新greasewhich能承受250℃，低磨损，从而提高theability位密封润滑耐高温系统的高温。

工地

这种钻头可以申请专利定向插入andchisel放倒齿，并在方向垂直于切割meansmounted齿，从而使更大量的岩石切割，同时提高机械钻速。 此外，定向齿轮，以提供均匀的压力，因为teethprevent齿的角部承受高负载，从而降低了thecr​​ushing牙齿和牙齿破碎。

Productintroduction: H series drill head is O shaped rubber sealing sliding bearingdrill, drill press can bear higher in the conventional speed. The mainstructure characteristics:

1. Uses the highstrength and high toughness of cemented carbide tooth, which improves theability to resist impact teeth and reduce tooth broken rate;

2. Optimizationdesign of the tooth row number, number of teeth, teeth height and unique alloytooth shape gives full play to the bit cutting and cutting speed;

3. Use circliplocking cone, which can bear high pressure;

4. Antifrictionalloy inner hole weld increases bearing anti-seizure ability;

5. Use highsaturation Ding nitrile rubber O – ring andTricone bitseal compression optimization improves the reliability ofbearing seal;

6. Use the limitpressure and prevent the rubber tube drilling fluid into the lubricationsystem, which supply good lubrication for the bearing system and ensure thatthe O ring the normal work and improve the work life of drill bit;

7. Use new greasewhich can bear high temperature of 250 ℃ and low wear, which improve theability of bit sealed lubrication system of high temperature resistance.

Construction Site

This drill can be patented directional inserts andchisel tipped teeth, and in the direction perpendicular to the cutting meansmounted teeth, so that a greater amount of rock cutting, while increasing ROP. Moreover, the directional gear to provide uniform pressure, because the teethprevent the corners of the tooth to withstand high loads, thus reduces thecrushing teeth and teeth broken.
