Key working elements for demanding drilling environments
Our Rock Drilling Inserts are manufactured for demanding drilling environments where penetration efficiency, insert retention, and service life directly affect operating cost. Produced in WC-Co and selected WC-Co-Ni grades, these inserts are designed to handle hard rock, fractured formations, abrasive strata, and heavy impact loads.
Rock Drilling Inserts are key cemented carbide working elements used in rock drilling bits, DTH hammers, down-the-hole drilling tools, and geological drilling equipment. They work under high impact, high contact stress, and severe abrasive wear conditions.
Manufacturing & Quality Control
Our rock drilling inserts are produced through controlled powder preparation, pressing, vacuum sintering, optional HIP densification, and precision grinding.
- Matching grain size and cobalt content with high-impact conditions
- Sintering shrinkage rate and dimensional consistency
- Structure uniformity, porosity, and abnormal grain control
- Working end chamfer and surface integrity control
- Assembly matching control with steel body
Selection Recommendations
Choose the right insert for your ground conditions:
- **High-abrasion, low-impact rock**: prioritize higher hardness grades
- **High-impact, fractured rock**: prioritize grades with higher toughness and cobalt content
- **Hot fitting or brazing assembly**: confirm matching dimensions, tolerance zones, and heat-affected requirements
- **Penetration efficiency sensitive**: optimize bit shape, layout method, and insert protrusion simultaneously
