Take a bite out of tough conditions. Ruggedly constructed with work-hardened, high-alloy steel, this reamer incorporates a unique, steep, rear-tapered design for ease of push back when needed. Optional built-in swivel or thru-shaft designs are also available. High-wear areas are made to last with a resilient carbide mesh grit hard facing. Equipped with oversized Shark Teeth tooling for aggressive, yet smooth, cutting action, the T-Rex is ready for cobble, chunk rock and soft rock.
