Product Description

The Tricone Bit is the most versatile drill bit on the market. It is the drill bit in most styles of drilling. Whether you are drilling a water well or an oil well, Lockheed has the tricone drill bit for you.



TCI(Tungsten Carbide Insert) tungsten carbide roller bits

TCI(Tungsten Carbide Insert). These tricones are designed for soft to very hard formations depending on the style and quantity of the carbides on the drill bit. Because of its versatility and performance, it's still one of the main Rock Bits in use today. It is widely used for oil&gas, water well, geotechnical, environmental, geothermal, construction, exploration and mining drilling.



Precision bearings made with the tightest tolerances in the industry! The bearing materials used have extremely low friction and high load capacity. Chemically heat resistant, heat tolerant HNBR materials for bearing seal and pressure compensator. This material is very compatible with oil based muds air cooled and open bearings are also available.


Put more active cutting elements on gauge than anyone in the industry. Perfect for directional applications. Its gauge holding ability is superior for maintaining gage on lateral or extreme build angles. We can offer diamond in this feature for the most abrasive applications. Bearing and seal life are extended by keeping the cone from rubbing the hole-wall and generating additional heat.


Design flexability offers customers the ability to effectively clean the cutting structure, while minimizing cone erosion. Premium nozzles are used for consistentcy and reliability.


Used in

Common IADC


Clays, coal, salts, shales, soft limestone,

discontinuous sands etc...



Sedimentary rocks, limestone, sandstone,

slate etc...



Varieties of silica, basalt, dolomite, compact

sands, limestone etc...


Ultra Hard

Marble, quarzite, granite, gneiss, pyrite, etc...


Sealed Bearing tci tungsten carbide roller bits with or without gauge protection

These are the best preforming and longest lasting style of tricone on the market. Sealed bearings will out perform open bearings. Gauge protection greatly increases the life of the drill bit.


Open Bearing tci tungsten carbide roller bits with or without gauge protection

Open bearing tricones can be gauge protected or not. These tricone bits have exceptional value, good performance and low cost. Gauge protection greatly increase the life of the drill bit.
