1.金属面密封轴承TCI位
切削结构	优质钨硬质合金刀片的耐久性与新配方和插入位的新技术改进。
计结构	与计剪的脚跟和压力表插入多计保护，锥，钨硬质合金刀片和堆焊在下摆增加的规表面衡量保持能力和轴承寿命。
密封轴承结构	轴承1.耐磨性和抗咬合性得到改善，并适用于高转速。 2.先进的金属密封包将提高轴承密封件的可靠性和耐久性。
大类可得到	尺寸：6'，6 1/2'，7 1/2'，8 1/2“，9 1/2'，9 5/8”，9 7/8'，12 1/4“，17 1 / 2'，等等。 IADC码：4-系列，5-系列，6-系列等。

三牙轮钻头Cuttingstructure：很长的间隔较宽，凿形刀片和相当coneaxis对位的中心线偏移保证很高的普及率。 Tosecure从直径损失该位，保径镶已经得到了上面的shorterlength和更大的角度。阵型：长的时间间隔非常softpoorly压实的页岩，砂岩，粘土，盐和软mestones的。尺寸andIADC可供选择：2 7/8至26 IADC 114 117 216 217 317 321 417437 517 537 617 637等。

1. Metal-face sealed bearing TCI Bit
Cutting Structure	The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.
Gauge Structure	Multiple gauge protection with gauge trimmers on heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.
Sealed Bearing Structure	1. Abrasion resistance and seizure resistance of the bearing are improved and suitable for high rotary speed. 2. The advanced metal seal package will improve the reliability and durability of bearing seal.
Main Type Available	Size: 6', 6 1/2', 7 1/2', 8 1/2', 9 1/2', 9 5/8', 9 7/8', 12 1/4', 17 1/2', etc. IADC Code: 4- Series, 5- Series, 6- Series, etc.

Tricone bit Cuttingstructure: very long widely spaced , chisel-shaped inserts and considerable coneaxis offset against center line of bit ensure very high penetration rate . Tosecure the bit from diameter loss, the gage protection inserts have got shorterlength and greater angle of the top. Formations: long intervals of very softpoorly compacted shale, sandstone, clays, salts and soft mestones. Size andIADC available: 2 7/8 to 26 IADC 114 117 216 217 317 321 417437 517 537 617 637 and so on.
