Rock Reamer
Premium offers standard rock reamers which are available in a wide variety of cutting structures including Milled tooth bit (IADC117~347) and TCI bit (IADC 417~847)and sizes from 8″~78″ covering the entire range of HDD rock drilling applications. We stocks certain standard sizes but can also custom make tools to meet specific customer requirements.
Rock reamer
Rock reamer is a specialized drilling tool used to enlarge boreholes in hard rock formations. Its design features cutting elements attached to cutters that rotate around a central shaft. Rock reamers are crucial for various drilling applications, helping ensure the successful installation of pipes in challenging geological conditions.
Bearings and Seals
High-quality bearings and seals are used to support the rotation of the rock reamer. These components are essential for maintaining the tool’s integrity and preventing premature wear.
Stabilization
Some rock reamers incorporate stabilizer pads or arms that help centralize the tool within the borehole. Stabilization is important to ensure that the reamer cuts evenly and prevents the tool from becoming stuck or deviating off course.
Sizes
Rock reamers come in various sizes, allowing for the enlargement of boreholes to different diameters. The size of the reamer needed depends on the initial borehole diameter and the target size required for accommodating pipes or casings.
Application
Rock reamers are commonly used in horizontal directional drilling (HDD), where precise drilling are required. They are also used in vertical drilling operations, such as oil and gas well construction, to enlarge boreholes before inserting casing.
Rock reamer can prove to be a great cost effective solution due to the cost and limited availability of large diameter bits. They also enable larger holes to be drilled with smaller rigs by drilling in stages.
Block-leg Cutter Rock reamer
Premium upgraded rock reamer utilizes an Block-leg- cutter along with a durable and reamer body. This platform enables customers to use heavy-duty block-leg cutters across multiple bores to reduce overall tooling costs and increase profitability. We provides three high performance cutter options (MT/TCI/ Premium TCI) allowing customers to address the full spectrum of ground conditions. Rock reamer is available in sizes ranging from 28” up to 72” and cutters are available from IADC117 ~IADC847.
This upgraded rock reamer offers the ability to effectively increase reaming pass sizes in soft-medium-hard rock over longer bore holes, thereby increasing drilling performance and providing lowest cost per foot drilling.
