产品优势：

最广​​泛的一种石油钻井和地质钻探牙轮钻头。 牙轮钻头的冲击，挤压和剪切破碎旋转岩石的作用，所以牙轮钻头能适应各种阶层软，中，硬的。 尤其是喷射式牙轮钻头和牙轮钻头牙轮钻头喷嘴的外观后，钻井速度大大提高，这是在牙轮钻头发展史上的伟大革命。 牙轮钻头按牙型可分为铣（钢牙）齿牙轮钻头。 （岩镶嵌在硬质合金齿牙轮钻头;根据所述锥体号码）可以被分为单，双锥体滚筒，辊和三辊位。 目前，在国内和国外，最常见和最广泛的一种为三牙轮钻头。

在石油钻井业及各类牙轮钻头，它是牙轮钻头的不可缺少的重要组成部分，但对于一些钻井行业，价格过高，从而导致了一些钻探行业不得不在二级锥的极大兴趣 位。 它的价格低，质量可靠（在使用仅1/3的生活石油钻井），减少了大量成本的钻井行业​​。 所以牙轮钻头的秒针已成为一些钻探行业的重要组成部分。

Product advantages:

The most widely used one in oil drilling and geological drilling is cone bit. Cone bit is of impact, crushing and shearing crushing rock role in rotation, so cone bit can adapt to various strata of soft, medium and hard. Especially after the appearance of jet type roller bit and rock bit cone bit nozzle, the drilling speed is greatly improved, which is a great revolution in the history of the development of cone bit. Cone bit by tooth type can be divided into milling (steel teeth) teeth roller bit. (rock inlaid on the hard alloy tooth roller cone bit; according to the cone number) can be divided into single, double cone roller, roller and a three roller bit. At present, at home and abroad, the most common and most used one is three cone bit.

In the oil drilling industry and all kinds of cone bits, it is an important and indispensable part of roller bit, but for some of drilling industry, the price is too high, which has led some drilling industry had a great interest in the secondary cone bit. Its price is low and quality is reliable (in petroleum drilling using only the life of 1/3) , reduces a lot of cost for drilling industry. So the second hand of cone bit has become an important part for some drilling industry.
