Product Description
[What This Product Does]
This 115mm DTH hammer bit penetrates hard rock formations 40% faster than standard bits by optimizing impact energy transfer. It solves the industry challenge of slow drilling progress in granite, basalt, and quartzite where conventional bits struggle with penetration rates below 0.3m/min.
[Key Features & Technical Specifications]
• Impact Mechanism: Balanced piston design delivering uniform force distribution
• Button Configuration: Tungsten carbide inserts arranged for maximum coverage (85-92% face coverage)
• Body Material: Forged 42CrMo alloy steel with 58-62 HRC surface hardness
• Connection Type: Standard API thread compatible with most DTH hammers
• Operating Pressure: 15-25 bar standard range (high-pressure versions available)
[Performance Advantages]
1. Penetration Rate: Achieves 0.8-1.2 m/min in medium-hard formations (80-120 MPa)
2. Service Life: 800-1200 meters in granite under normal operating conditions
3. Wear Resistance: Button loss rate below 3% per 100 meters in abrasive formations
4. Air Consumption: 15-22% reduction compared to conventional designs
[Application Scenarios]
• Water Well Drilling: Ideal for municipalities and agricultural operations requiring deep water sources
• Mining Exploration: Used in mineral prospecting where core recovery isn't required
• Geothermal Projects: Suitable for 150-300 meter depth geothermal exchange boreholes
• Construction Piling: Foundation drilling in rocky terrain for bridges and buildings
[Problem-Solving Capabilities]
This DTH bit specifically addresses:
• Slow penetration in quartz-rich formations where conventional bits stall
• Premature wear in highly abrasive sandstone layers
• Inconsistent performance at varying depths and pressure conditions
• Frequent downtime for bit changes in deep drilling operations
[Recommended Usage Parameters]
• Optimal RPM: 40-60 rotations per minute
• Recommended Air Pressure: 18-22 bar for standard operation
• Maximum Depth: 350 meters with proper flushing
• Suitable Formations: Granite, basalt, hard limestone, quartzite
