Product Overview

The 3050H-22 Standard Rotary Drilling Bullet Tooth is a reliable and high-performance drilling wear part designed for rotary drilling rigs, foundation piling, rock augers, and general hard ground excavation applications.

Featuring a Ø22mm tungsten carbide cutting tip and a durable steel body with hardfacing wear protection, this standard rotary drilling tooth provides excellent cutting performance, impact resistance, and wear durability in various geological conditions.

Manufactured from forged 42CrMo alloy steel and precision heat-treated, the 3050H-22 offers a balanced combination of strength, toughness, and abrasion resistance. The reinforced hardfaced surface helps protect the steel body from abrasive soil and rock erosion, extending service life and reducing replacement frequency.

With its standard Ø30mm shank design, the 3050H-22 is widely compatible with rotary drilling equipment and is an ideal choice for contractors requiring stable drilling performance, reliable wear resistance, and cost-effective operation.

Technical Specifications

Key Features & Performance Advantages

1. Ø22mm Tungsten Carbide Cutting Tip

The 3050H-22 is equipped with a Ø22mm tungsten carbide tip, providing excellent cutting efficiency and penetration performance.

Compared with smaller carbide tips, the enlarged carbide insert offers:

• Higher rock crushing capability
• Improved wear resistance
• Longer working life
• Better performance in abrasive formations

It is suitable for medium-hard rock, weathered rock, gravel layers, and compact soil conditions.

2. Hardfacing Wear Protection

The tooth body features a circumferential hardfacing wear-resistant layer that protects against abrasive soil and rock wear.

This surface reinforcement helps:

• Reduce steel body erosion
• Maintain tooth strength
• Extend service intervals
• Lower replacement costs

The hardfaced design improves reliability during continuous rotary drilling operations.

3. Forged 42CrMo Steel Body

Manufactured from high-quality 42CrMo alloy steel, the 3050H-22 body provides excellent mechanical strength and durability.

After precision heat treatment, the steel structure delivers:

• High bending resistance
• Strong impact tolerance
• Reliable fatigue performance

ensuring stable operation under normal rotary drilling conditions.

4. Secure Carbide Brazing Technology

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

This advanced brazing process ensures:

• High bonding strength
• Reduced carbide loosening
• Improved impact reliability
• Consistent drilling performance

5. 360° Self-Rotating Performance

Designed for standard Ø30mm rotary drilling holders, the 3050H-22 allows smooth rotation during operation.

The self-rotating structure provides:

• Uniform wear distribution
• Self-sharpening cutting action
• Lower drilling resistance
• Stable penetration efficiency
