18'' trenchless HDD rock hole opener reamer bit

Specification

The cutting teeth of the cone use TCI cutters or Steel tooth cutters. And the teeth have good wear resistance and the speed of the drill is fast. Intensive palm tip welding and full palm back protection, the cones are divided into back dimension and the diameter is protected by a protective design to effectively enhance the resistance of the drill bit.

Apply wear-resistant alloy or carbide tooth on the front stiffener or block surface. In order to reduce the weight of the rock reamer hole opener without affecting the support strength, the front centralization plate adopts a hollow design.

Features

The staged TCI cone hole opener incorporates precision-engineered cone structures to ensure fast, smoothly drilled in trenchless application, high-quality, concentric hole opening under a wide range of oil drilling application. TCR HDD tools are run successfully on rotary and rotary steerable assemblies in both straight and deviated holes.

A range of milled tooth and tungsten carbide insert (TCI) cutting structures are available for a variety of formation conditions. The fixed-diameter hole opener is available in sizes165mm to 2000mm, with hand-tool demountable cutters that are easily replaced . The robust design and construction enable drilling of longer intervals.
