Detailed Product Content

1. Core Product Characteristics

1.1 Premium Materials & Precision Craftsmanship

Crafted with a high-grade H13 alloy steel body (heat-treated at 1100℃ for superior toughness) and YG11C/YG13C tungsten carbide tips (density ≥14.9g/cm³), our thread drill bits withstand extreme drilling conditions without deformation or tip breakage. Key craftsmanship highlights:

Precision CNC machining ensures consistent thread pitch and tip angle (118°/135° optional), reducing drilling resistance.
Carbide tips are brazed with high-temperature solder (≥850℃) for firm bonding—no tip detachment during high-speed drilling.
Standard outer diameters: 8mm-50mm; customizable range: 5mm-80mm to match diverse hole size requirements.
Available in three core types: Cross-cut (soft rock), Ball-tooth (hard rock), and Clay-specific (sticky soil/soft sedimentary rock).

1.2 Global Standard Compliance & Durability

The product is ISO9001 certified and complies with international standards including ISO 6411, ASTM E250, EU CE, Russian GOST, and Australian AS 2341. To adapt to harsh environments:

Surface treatment options: Hot-dip galvanizing (430-600g/㎡) for humid mines; epoxy coating for coastal/salt spray regions (corrosion resistance meets ISO 12944 C5-M).
Working temperature range: -40℃ to 120℃, suitable for permafrost, high-temperature mines, and tropical exploration projects.
Service life: ≥500 drilling meters for hard rock; ≥800 drilling meters for soft rock—40% longer than industry average.

2. Global Geological Adaptation Scenarios

Our thread drill bits are customized to match unique geological conditions worldwide, eliminating "one-size-fits-all" inefficiency:

2.1 Hard Rock (South Africa, Australia, Canada)

Drill bit type: Ball-tooth with YG13C carbide tips (HRC ≥65)
Key advantages: Reinforced tip structure resists impact; 135° tip angle reduces penetration resistance in granite/quartzite.
Application cases: South African gold mines, Australian iron ore exploration—penetration speed 30% faster than standard bits.

2.2 Soft Rock/Sedimentary Rock (Southeast Asia, Middle East)

Drill bit type: Cross-cut with sharp YG11C carbide edges
Key advantages: Wide cutting surface reduces energy loss; spiral thread design enhances chip removal in sandstone/siltstone.
Application cases: Vietnam highway geological surveys, Indonesian coal mine drilling—completes 10km drilling 25% faster.

2.3 Permafrost Rock (Siberia, Northern Canada)

Drill bit type: Low-temperature resistant alloy body + YG11C tips
Key advantages: Alloy body withstands -40℃ cold without brittleness; anti-freezing coolant compatibility.
Application cases: Russian frozen rock exploration—stable operation in extreme cold with no performance loss.

2.4 Corrosive/Coastal Environments (Australia, Indonesia)

Drill bit type: Epoxy-coated body + corrosion-resistant carbide tips
Key advantages: Epoxy coating prevents salt spray/acidic water erosion; sealed brazed joints avoid moisture damage.
Application cases: Australian coastal sandstone projects, Indonesian port infrastructure drilling—service life extended by 50%.

3. Technical Advantages

3.1 High Penetration Efficiency

Spiral thread design + optimized tip angle reduces drilling resistance by 25%, cutting project time significantly.
High rotational speed compatibility (800-2000 rpm) adapts to handheld/automated rock drills (Atlas Copco, Sandvik, and local brands).

3.2 Superior Wear Resistance

Tungsten carbide tips with 30% higher density than industry standards—resist wear in abrasive rock.
Heat-treated H13 alloy body enhances toughness, preventing breakage in high-vibration drilling.

3.3 Universal Compatibility

Fits global standard rock drill interfaces, eliminating equipment mismatch for cross-border projects.
No special adapters required—reduces on-site training and tool replacement costs.

3.4 Cost-Effective Performance

Long service life reduces drill bit replacement frequency by 40%.
Customized design avoids over-engineering, matching performance to project needs without unnecessary costs.

4. Step-by-Step Installation & Maintenance Guide (with Regional Adaptation)

4.1 Pre-Installation Preparation

Tools Required: Global standard rock drill (handheld/automated), compatible adapter, coolant (mineral oil for hard rock; water-based for soft rock), caliper, cleaning brush, anti-rust lubricant.
Geology Check: Confirm rock type/hardness and select matching drill bit (e.g., ball-tooth for hard rock, cross-cut for soft rock).
Drill Bit Inspection: Check for carbide tip damage, thread wear, and coating integrity—replace defective bits before use.

4.2 Standard Installation Steps

Attach the drill bit to the rock drill using a compatible adapter—tighten firmly to avoid vibration-induced loosening.
Apply appropriate coolant: Mineral oil for hard rock (reduces tip overheating); water-based coolant for soft rock (controls dust).
Adjust drilling parameters: 800-1200 rpm for hard rock; 1500-2000 rpm for soft rock—avoid excessive force to prevent tip damage.
Drill vertically (or at designed angle) with steady pressure—stop periodically to clear chips and cool the bit.
Post-drilling: Clean the bit with a brush to remove residual chips; inspect tip wear (replace if wear exceeds 3mm).

4.3 Regional Maintenance Precautions

Hard Rock Regions (South Africa/Australia): Use high-pressure mineral oil coolant; check tip wear every 50 drilling meters. Store bits in dry, shockproof containers.
Soft Rock Regions (Southeast Asia/Middle East): Clean chip grooves regularly to prevent clogging; use water-based coolant to avoid dust pollution.
Permafrost Regions (Siberia): Pre-heat the drill bit to 5-10℃ before use; use anti-freezing coolant. Avoid long idle time to prevent re-freezing.
Coastal Regions (Australia/Indonesia): Rinse bits with fresh water after use to remove salt residue; apply anti-rust lubricant before storage.
