The 6 3/4" Mean Green Extreme Tricone Bit is the newly improved version of the trusted Mean Green Standard Tricone Bit, designed to push the boundaries of Horizontal Directional Drilling in hard rock to an entirely new level. Built with cutting-edge technology and enhanced materials, the Mean Green Extreme is engineered for maximum power, efficiency, and durability in the most demanding drilling environments.
One of the most significant advancements in the Mean Green Extreme is its revolutionary Power Jet™️. The Power Jet™️ replaces the three traditional jets, with one jet located in the center of the cones. This innovative feature increases fluid pressure precisely where it’s needed most during drilling, virtually eliminating frac-out while requiring significantly less drilling fluid overall. The Power Jet™️ not only optimizes the cleaning of the bit and borehole but also reduces hydraulic costs and environmental impact, making it an eco-friendlier and more cost-effective choice for your projects.
Durability takes a giant leap forward in this version with the incorporation of chunky carbide shanks. This robust improvement to the shanks is designed to withstand extreme wear and tear far better than traditional bits. The chunky shanks extend the bit’s lifespan by absorbing and resisting the intense forces encountered during drilling in hard rock, leading to less frequent replacements and lower operational downtime. This upgrade ensures that the Mean Green Extreme remains sharp and effective throughout long and challenging drilling tasks.
Similarly to the standard version, the Mean Green Extreme boasts high-quality carbide materials and deep set seals, which continue to protect internal components from contamination and maintain smooth rotation under pressure. This combination guarantees superior endurance and dependable performance during long shots where precision and reliability are critical.
Optimized specifically for Horizontal Directional Drilling applications in hard rock, the Mean Green Extreme is the top-tier choice for professionals who demand cutting-edge technology and unparalleled resilience. With enhanced fluid efficiency from the Power Jet™️and tougher, chunkier carbide shanks, this bit delivers superior drilling power, longer life, and reduced operational costs.
For those ready to take on the toughest drilling challenges, the Mean Green Extreme is your ultimate partner underground—powerful, precise, and built to outperform its competitors.
