60kg Specification Full Size Tricone Bit for Oil Well Drilling Production

Short Description:

This full-size tricone bit with a weight of 60kg is a professional drilling tool tailor-made for oil production operations. Adopting high-strength alloy steel as the base material and embedded wear-resistant hard alloy teeth, the bit features a robust three-cone structure that delivers powerful rock-breaking capacity to cope with soft, medium and hard composite formations encountered in oil well exploitation.

Equipped with optimized pressure compensation and sealed lubrication system, it effectively prevents mud intrusion and reduces friction loss during long-duration downhole drilling, greatly extending the service cycle and lowering frequent replacement costs. The precisely machined gauge protection structure maintains stable wellbore diameter, improving drilling straightness and overall construction efficiency.
With a complete standard specification of 60kg, this tricone bit boasts stable overall rigidity and excellent shock resistance, perfectly matching conventional drilling rigs for onshore oil production wells. It is widely adopted by oilfield service companies as a reliable and cost-effective drilling accessory for daily oil extraction and well completion projects.
