简介：
牙轮钻头在当今的工业领域广泛应用，如采矿、水井、油井和地热钻探等等。除了AM和AX系列的钻头外，傲石捷长期以来也经营其他系列的牙轮钻头。特别是小直径的(直径8 1/2寸一下)，我们已能提供性价比非常高的产品，包括钢齿和镶齿钻头。
镶齿钻头比钢齿钻头耐用，但生产成本也更高。这两种钻头我们都能提供如下设计：
开放式轴承或密封轴承；
滚动轴承或滑动轴承；
有无保径设计等等；
钻头IADC号： 涵盖1 到 8系列，例如111, 131, 124, 532, 642, 722, 832, 114, 125, 515, 545, 645, 735, 845, 126 117, 137, 437, 517, 537, 637等等；
钻头直径：尺寸从 3 3/8寸(85.7毫米)到26寸(660.4毫米)；
用途： 水井，油井，地热井钻探等等。
