What Are DTH Hammer Bits and Carbide Mining Buttons?
DTH hammer bits are down-the-hole drill bits featuring carbide mining buttons (tungsten carbide inserts) for percussive drilling in mining and quarrying. Hemispherical buttons excel in hard rock by absorbing impact and resisting wear. Rettek produces tungsten carbide buttons through its full in-house chain, from raw alloy preparation to pressing and vacuum sintering, ensuring consistent quality for mining drill buttons.
Why Are Impact-Resistant Carbide Buttons Essential for Hard Rock?
Impact-resistant carbide buttons are vital for hard rock due to high shock loads causing fractures and downtime in DTH drill bit carbide buttons. Rettek's proprietary vacuum sintering delivers uniform grain size for superior toughness, solving frequent replacement issues and extending service life through wear, impact, and corrosion resistance.
Rettek Expert Views: "Our carbide buttons feature multiple grades selected by stone material, equipment model, and crushing time, optimizing wear resistance, impact resistance, and high corrosion resistance. Full in-house production from batching to vacuum sintering ensures unprecedentedly stable performance, preventing breakage in high-impact environments like hard rock drilling." – Rettek Engineering Specialist
How Does Rettek's Full In-House Production Chain Ensure Quality?
Rettek's chain covers alloy preparation, batching, pressing, vacuum sintering, tool design, production, and automated welding, providing full control over button bits for mining hammers. This surpasses outsourced competitors by guaranteeing uniform microstructure from ball milling, higher strength via unique welding, and cost optimization for reliable carbide buttons.

What Makes Rettek's Vacuum Sintering Superior for Impact Resistance?
Rettek's vacuum sintering uses proprietary temperature control for uniform grain size with no heat differences, achieving dense cemented carbide for hard rock drilling carbide inserts. This yields tungsten carbide drill buttons with exceptional impact toughness, wear resistance, and corrosion resistance, stable in abrasive conditions to cut costs for drill operators.
How Can Custom Grades Maximize Your DTH Hammer Performance?
Custom grades tailor WC/Co ratios based on rock type and DTH model, like higher impact grades for basalt or granite. Rettek's expertise matches DTH hammer bits specs with advanced welding for secure fit, maximizing uptime. Proven in 10+ countries, this reduces downtime via optimal wear and impact resistance.
What Carbide Button Grades Comparison Shows for Hard Rock Applications?
Rettek offers multiple grades for carbide buttons, selected by stone material, equipment, and conditions, balancing wear, impact, and corrosion resistance. Use this as a selector for procurement in crushing and drilling.
| Grade Focus | Key Properties | Rock Suitability | Life Extension | Applications |
|---|---|---|---|---|
| High Impact | Impact resistance prioritized | Hard rock like granite | 2-5x longer | DTH hammers, mining |
| Wear-Focused | Wear + corrosion resistance | Abrasive hard rock | Extended service | Drilling, crushing |
| Balanced | Wear, impact, corrosion | Varied hard rock | Stable performance | Mining, quarrying |
| High Corrosion | Corrosion + impact | Corrosive hard rock | Reduced downtime | Wet mining ops |
| Custom | Tailored to conditions | Specific rock/DTH | Optimized life | HPGR, VSI synergy |
Which Welding and Brazing Techniques Extend Button Life?
Rettek's automated welding and proprietary brazing create crack-free bonds with higher strength than bonded methods, preventing delamination in high-impact mining drill buttons. Processes ensure wear-resistant carbide securely attaches, extending life in harsh conditions like VSI crusher carbide tips.
