INROCK’S patented XTR-W® reaming platform provides a high-quality alternative to traditional “split bit” reamers to an affordable price. The streamlined design utilizes INROCK’s proven segment technology to deliver a performance drilling tool at an attractive price point.  It can be reused with the change of cutters and can be used with a variety of rig sizes. It is a fully flexible solution where the cutter is replaceable to fit different geologies leading to an optimal penetration rate and maximum service life.
The XTR-W® HF Cutter for hard rock is especially well suited for medium rig customers and complements already existing cutters for soft and medium rock formations.

Features and benefits

More TCI Coverage than other cutters in the market
Maintain insert coverage in abrasive & hard rock. Less risk of gauge failure

Updates performed to cutting structure
Optimal flushing for harder rock cuttings

Less aggressive TCI outline
A spherical shape to reduce the risk of fracture vs. a more aggressive shape. More wear resistant in harder rock that a ballistic insert

New chemical composition of TCI
More resistance in hard, abrasive and fissured rock. Sandvik premium tungsten carbide, made in Sweden


All XTR-W tools undergo a rigorous design process including finite element analysis (FEA). INROCK utilizes dynamic computer-based simulations to ensure tools can withstand the rigors of HDD operations before they go downhole. This includes utilizing our proprietary methodology to analyze the impact of a tight radius or dogleg formations. All XTR-W tools are manufactured in-house providing full traceability of each component. In addition, all tools undergo demanding quality control measures including the inspection of all welds by a 3rd party. All of this contributes to delivering a high-quality tool every time.
