风冷滚子轴承位
切削结构	优质钨硬质合金刀片的耐久性与新配方和新工艺，新技术的改进。
计结构	压力表保护与锥，钨硬质合金刀片和堆焊在下摆增加的规表面计插入衡量保持能力。
轴承结构	风冷滚子轴承包。球锁定锥，这减少了锥滴最小的概率。
主要类型可用	大小：8 1/2“，9 1/2'，9 5/8”，9 7/8'，10 5/8“，12 1/4'等 IADC代码：5系列，6系列，7系列

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。

Air Cooling Roller Bearing Bit
Cutting Structure	The durability of premium tungsten carbide insert is improved with new formulas and new techniques and new techniques.
Gauge Structure	Gauge protection with gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability.
Bearing Structure	Air cooling roller bearing package. Balls lock the cone, which reduces the probability of cone-dropping to minimum.
Main Type Available	Size: 8 1/2', 9 1/2', 9 5/8', 9 7/8', 10 5/8', 12 1/4', etc. IADC Code: 5- Series, 6- Series, 7- Series

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.
