TCI位系列：

1）.Soft形成TCI triconebits：

软formationTCI牙轮钻头用于钻探低抗压强度，非常softformations。 该位最大化使用的大直径和高值预测两个圆锥形和凿子碳化钨刀片。 这种切割structuredesign，结合最大锥偏移，导致高比特penetrationrates。 的刀行深压弯防止想逃位在stickyformations。

2）.Medium形成TCI牙轮钻头：

中等formationTCI牙轮钻头的功能在theheel行和内部行积极的凿钨硬质合金刀片。 这种设计提供了媒体的快速钻速和addedcutting结构耐久性至中硬的mations。 该HSNrubber O形圈提供足够的密封轴承的耐用性。

3）.Hard形成TCI牙轮钻头：

硬formationTCI牙轮钻头可用于钻硬和磨料地层。 Wearresistance碳化钨刀片被用于所述外围行，以防止lossof位计。 半球型刀片最大的数字被用在allrows提供刀具的耐用性和寿命长。

4）.Medium硬地层TCI牙轮钻头：

中等hardformation TCI牙轮钻头具有强大的凿钨硬质合金刀片onthe后排和锥形的内部行。 这种设计提供了一个fastdrilling率并增加切割介质结构耐久性中等hardformations。 在HSN橡胶O形圈提供足够的密封的bearingdurability。

TCI bits series:

1) .Soft formation TCI triconebits:

The soft formationTCI tricone bits are used to drill low compressive strength, very softformations. This bit maximized to use of both conical and chisel tungstencarbide inserts of large diameters and high projection. This cutting structuredesign, combined with maximum cone offset, results in high bit penetrationrates. The deep intermesh of cutter rows prevents bit bailing in stickyformations.

2) .Medium formation TCI tricone bits:

The medium formationTCI tricone bits features aggressive chisel tungsten carbide inserts on theheel rows and inner rows. This design provides a fast drilling rate and addedcutting structure durability in medium to medium hard for mations. The HSNrubber O-ring provides adequate sealing for bearing durability.

3) .Hard formation TCI tricone bits:

The hard formationTCI tricone bits can be used to drill hard and abrasive formations. Wearresistance tungsten carbide inserts are used in the outer rows to prevent lossof bit gauge. Maximum numbers of hemispherical shaped inserts are used in allrows to provide cutter durability and long life.

4) .Medium hard formation TCI tricone bits:

The medium hardformation TCI tricone bits features robust chisel tungsten carbide inserts onthe heel row and conical on the inner rows. This design provides a fastdrilling rate and added cutting structure durability in medium to medium hardformations. The HSN rubber O-ring provides adequate sealing for bearingdurability.
