Block-leg Cutter
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.
Bit Specification
This type of Roller cone cutter is designed for no-dig rock drilling tools.
Different tooth shapes are selected for different engineering conditions of customers, and can be customized.
Features
Bearing: This series of Roller cone adopts a floating bearing metal sealed structure suitable for high rotational speed, while applying a new type of synthetic grease to improve the working environment of the bearing, which has a longer service life and higher reliability under the working condition of using screw drilling.
Option Features
Design features and structure:
1. The palm back alloy is strengthened to prevent excessive wear of the rock mass on the palm back during horizontal drilling.
2. Aiming at the characteristics of easy wear of the palm tip during horizontal or directional construction, high wear-resistant alloy materials are deposited on the palm tip and the entire palm back edge of the product to provide better protection and wear resistance, reducing the exposure and damage of bearings caused by premature wear of the palm tip. Improve the service life of drilling tools.
