Product Description

The ROSCHEN Customized DTH Button Bits for Reverse Circulation (RC) drilling are precision-engineered drilling consumables designed to deliver maximum penetration rates and extended service life in the most demanding geological formations. Manufactured from premium alloy steel forgings and fitted with high-grade tungsten carbide inserts, these DTH button bits provide exceptional wear resistance and impact durability across a comprehensive range of drilling diameters. Each button bit is CAD-designed using advanced geometric modeling software and CNC-machined to exacting tolerances, ensuring perfect bit body geometry and consistent performance. The bits undergo multiple heat treatment cycles to achieve optimal hardness distribution, followed by surface compression treatment for enhanced fatigue resistance under repeated high-impact loading conditions. Fully compatible with all major DTH hammer brands including Epiroc, Atlas Copco, and the complete ROSCHEN hammer series, these customized bits represent the ideal balance of quality, performance, and cost-effectiveness for professional drilling operations worldwide.

Key Features
  • Premium Tungsten Carbide Inserts: Each button bit features high-grade tungsten carbide buttons with optimized cobalt binder content, available in hemi-spherical, parabolic, and ballistic profiles to match specific rock formation characteristics.
  • Advanced Face Design Options: Select from flat face configuration for maximum penetration in hard competent rock, convex face for improved gauge protection in abrasive formations, or concave face for enhanced flushing in soft fractured ground.
  • Multi-Brand Shank Compatibility: Precision-ground shanks are engineered to fit DHD, COP, QL, SD, Mission, and BR series hammers, allowing customers to use a single source for bits across mixed hammer inventories.
  • Superior Flushing Design: Optimized flushing groove geometry and strategically positioned flushing holes ensure efficient cuttings removal from the hole bottom, preventing bit balling and maintaining consistent penetration rates.
  • Surface Compression Treatment: Post heat-treatment surface compression process introduces beneficial residual compressive stresses in critical wear areas, significantly increasing fatigue life and resistance to impact-related cracking.
  • Custom Manufacturing Capability: Full customization service available for non-standard diameters, special shank configurations, unique face designs, and application-specific carbide grade selection to meet specialized drilling requirements.

Applications

ROSCHEN customized DTH button bits for reverse circulation drilling are purpose-built for mineral exploration programs where accurate ore grade assessment depends on uncontaminated sample recovery through various geological formations. In open-pit mining operations, these bits deliver consistent performance in blast hole drilling applications across diverse rock types from soft limestone to extremely hard banded iron formations. The bits are extensively used in water well drilling projects where formation stability and precise lithological logging are critical for well design and screen placement decisions. Geotechnical investigation contractors rely on these RC bits for site characterization drilling where core sample integrity directly influences foundation design parameters and construction safety assessments. For quarry operations requiring efficient production drilling, the optimized button configurations and face designs provide the ideal balance of penetration rate and bit life tailored to specific rock properties. Environmental drilling programs also benefit from the clean sample recovery characteristics of reverse circulation bits when monitoring well installation requires accurate subsurface profiling.

Packaging and Quality Assurance

Every ROSCHEN DTH button bit undergoes comprehensive quality inspection at multiple production stages, including incoming raw material certification, in-process dimensional verification during CNC machining, post heat-treatment hardness testing, and final visual and dimensional inspection before packaging. Each bit is individually wrapped in corrosion-inhibiting VCI paper and secured in custom-fitted foam compartments within export-grade polywooden shipping boxes, providing maximum protection against handling damage and environmental exposure during international transit. Complete shipment documentation includes material test certificates, dimensional inspection reports, and a detailed packing list for customs clearance. ROSCHEN maintains comprehensive technical support services including application engineering consultation to help customers select optimal bit configurations for specific drilling conditions, on-site performance monitoring recommendations, and timely spare parts availability through regional distribution centers. Our ISO certified quality management system ensures consistent product performance across all production batches, giving drilling contractors confidence in every bit delivered to the drill site.

As a leading manufacturer of rock drilling consumables with extensive experience serving the global mining and construction industries, ROSCHEN is committed to providing drilling solutions that combine technical excellence with competitive factory-direct pricing. Whether you require standard catalog items or fully customized bit configurations for unique drilling challenges, our engineering team is ready to collaborate on developing the optimal solution for your specific application.
