3060D12-22 Wear-Resistant Carbide Button Rotary Drilling Bullet Tooth

Product Overview

The 3060D12-22 Wear-Resistant Carbide Button Rotary Drilling Bullet Tooth is an advanced drilling wear part designed for abrasive geological conditions, foundation piling, gravel formations, and long-duration rotary drilling applications.

As part of the Wear-Resistant Rotary Drilling Teeth series, the 3060D12-22 features a unique D12 carbide button protection design, integrating 12 tungsten carbide buttons embedded around the cutter head to improve wear resistance and protect the steel body from abrasive erosion.

Built with a standard Ø30mm shank system and Ø38mm step collar, this rotary drilling tooth features a reinforced Ø60mm head diameter, 70mm gauge length, and 130mm overall length.

The cutting structure combines a main Ø22mm coarse-grain tungsten carbide tip with 12 embedded carbide wear buttons around the conical shoulder. This dual protection system reduces steel body wash, minimizes abrasive wear, and extends service life in challenging drilling environments.

Manufactured from high-strength 42CrMo alloy steel, the 3060D12-22 provides excellent durability, stable rotation performance, and reliable operation for foundation drilling contractors worldwide.

Technical Specifications

Key Features & Performance Advantages

1. D12 Carbide Button Anti-Wear Protection System

The unique D12 carbide button structure integrates 12 tungsten carbide buttons around the conical head surface.

These embedded carbide buttons act as protective wear shields, helping to:

• Reduce steel body erosion
• Prevent abrasive slurry wash
• Protect the main carbide seat
• Extend drilling tooth service life

This design provides excellent wear resistance in continuous rotary drilling operations.

2. Ø22mm Tungsten Carbide Main Cutting Tip

The enlarged Ø22mm coarse-grain tungsten carbide insert delivers reliable cutting performance and long-term durability.

The premium carbide grade provides:

• High wear resistance
• Improved impact tolerance
• Strong fracture resistance
• Stable penetration performance

Suitable for:

• Abrasive rock
• Gravel layers
• Weathered formations
• Hard soil conditions

3. Ø60mm Reinforced Wear-Resistant Head

The wide Ø60mm head structure provides sufficient steel support for both the main carbide tip and embedded carbide buttons.

Benefits include:

• Improved structural stability
• Better wear protection
• Reduced body wash
• Longer operating intervals

The reinforced shoulder design helps maintain consistent drilling performance.

4. Anti-Eccentric Wear & 360° Self-Rotation

The distributed carbide button layout helps reduce uneven surface wear during operation.

Combined with the self-rotating design, the tooth provides:

• Smooth 360° rotation
• Uniform wear distribution
• Self-sharpening cutting action
• Reduced drilling resistance

This helps maintain stable penetration efficiency throughout the service life.

5. Optimized 70mm Gauge Length Design

The 70mm gauge length with 130mm overall length provides an effective balance between cutting clearance and structural durability.

Advantages include:

• Improved chip evacuation
• Reduced material accumulation
• Better drilling efficiency
• Stable operation in deep foundation projects
