Our API-certified steel tooth tricone bits feature milled teeth designed for optimal drilling performance in soft to medium formations. These bits are particularly effective in geological formations such as clay, shale, sandstone, and limestone. They are widely used in oil and gas drilling, geothermal exploration, and mining operations, offering high efficiency and cost savings compared to international alternatives.
SMKST’s milled tooth tricone bits are known for their durable build, enhanced by advanced designs that improve drilling speed and prolong the lifespan of the bits. Available in various sizes and IADC codes, these bits are suitable for a wide range of drilling needs. We offer competitive pricing on multiple versions of the same bit models, ensuring that clients receive both performance and value.
