Product Overview

The 3050H-19 Standard Hardfaced Rotary Drilling Bullet Tooth is a heavy-duty foundation drilling wear part designed for rotary drilling rigs, rock augers, core barrels, and piling applications in hard rock and highly abrasive ground conditions.

Featuring a Ø19mm tungsten carbide cutting tip and a reinforced steel body with hardfacing wear protection, this rotary drilling tooth delivers outstanding impact resistance, cutting performance, and extended service life in demanding drilling environments.

Manufactured from high-strength 42CrMo alloy steel and precision heat-treated, the 3050H-19 combines excellent toughness with superior wear resistance. The reinforced hardfaced body effectively reduces steel erosion caused by abrasive soil and rock fragments, helping protect the tooth structure and minimize replacement frequency.

Designed for professional foundation drilling contractors, this bullet Tooth provides reliable penetration performance, reduced downtime, and improved drilling efficiency in challenging geological formations.

Key Features & Performance Advantages
关键特性与性能优势

1. Heavy-Duty Hardfacing Wear Protection

The 3050H-19 features a specially reinforced hardfacing wear layer around the steel body, providing excellent resistance against abrasive soil, rock cutting, and continuous drilling wear.

This protective layer reduces premature steel wash and extends the service life of the drilling tooth, especially in highly abrasive geological conditions.

2. Premium Ø19mm Tungsten Carbide Cutting Tip

Equipped with a high-quality Ø19mm tungsten carbide insert, this bullet tooth delivers excellent hardness, impact resistance, and cutting efficiency.

The optimized carbide grade provides a balanced combination of toughness and wear resistance, allowing reliable penetration in:

• Hard rock
• Fractured rock
• Gravel layers
• Dense soil formations

3. Forged 42CrMo Alloy Steel Body

The tooth body is manufactured from forged 42CrMo alloy steel and heat-treated to achieve high mechanical strength.

With excellent bending resistance and fatigue durability, the 3050H-19 withstands:

• High rotary torque
• Heavy impact loads
• Continuous drilling vibration

ensuring stable performance during long working cycles.

4. Advanced Carbide Brazing Technology

High-frequency induction brazing creates a strong connection between the tungsten carbide tip and steel body.

This advanced bonding process improves shear strength and minimizes carbide loosening, cracking, or breakage during heavy-duty drilling operations.

5. Smooth 360° Self-Rotation Performance

Designed for standard Ø30mm rotary drilling holders, the 3050H-19 allows smooth 360° rotation during operation.

The self-rotating design helps achieve:

• Uniform wear distribution
• Longer tooth lifespan
• Consistent cutting performance
• Lower drilling resistance
