Carbide mining tools
have the potential to enhance efficiency, exhibit high wear resistance, and reduce tool wear.
Advanced material technology allows for the selection of various grades suitable for different mining and engineering tools, ranging from down-the-hole drill bits and roller cone bits to coal picks, rotary cutters, milling cutters, buttons, shields, and crusher tips (throw-aways).

Tungsten Carbide Mining Tools Built for Hard Rock
Mining tools work under extreme impact and abrasion. Yatech carbide mining inserts use high-toughness grades with controlled porosity and hot isostatic pressing (HIP) treatment, giving excellent resistance to chipping and fracturing in the hardest rock formations.
- Button bits: dome, spherical and ballistic button inserts for DTH and top hammer drilling
- Coal cutting picks: pick tips with high impact toughness for long service life
- Tricone bit substrates: precision-shaped substrates with optimized tooth geometry
- Construction tools: inserts for road milling, trenching and tunneling machines
All inserts are sintered and ground to customer specifications. Consistent grade quality batch after batch helps drilling contractors reduce downtime and replacement frequency.
Application - Grade - Benefit Matrix
Not sure which grade fits your case? Send us the working conditions and we will recommend one within 24 hours.
| Application | Recommended grade | Key benefit for you |
|---|---|---|
| Road milling / cold planing | Coarse grain, 10-12% Co | Extreme impact life on abrasive asphalt |
| Foundation drilling (rock) | Coarse grain, 12% Co | Low breakage rate in hard rock |
| Coal cutting picks | Medium-coarse, 10% Co | Longer pick life, fewer stoppages |
| Trenching / tunneling | Tough grade + brazed seat design | Fewer tooth replacements per shift |
| Conical / flat-press buttons | Sinter-HIP, porosity-controlled | Consistent brazing, fewer premature failures |
Frequently Asked Questions
Which mining tools do you supply?
Button bit inserts, picks, tricone bit substrates and rock drilling carbide in impact-resistant grades.
Which grades suit hard rock drilling?
Can you match OEM button geometry?
Yes — buttons and substrates are produced to drawing including dome, ballistic and wedge shapes.
Do you support custom sizes for mining carbide?
Yes. We produce to your drawings (PDF, DWG or STEP). Send specifications and our engineers will confirm feasibility and provide a quote within 24 hours.
What is the MOQ and can I order samples first?
There is no fixed MOQ for standard items. Sample orders are welcome so you can verify quality before volume production; shipping is freight collect.
