The 8 1/2" Mean Green Extreme Tri-Cone includes both the Power Jet™ and Chunk Carbide Shank for optimized drilling capabilities. The Power Jet™ virtually eliminates frac-out and budgets drilling fluid, while the Chunky Carbide Shank protects the seals and prevents premature breaking of the bit. The Mean Green Extreme offers top of the line performance.
