Product Overview
The 30606L-19 Wear-Resistant Rotary Drilling Bullet Tooth is a high-performance foundation drilling wear part designed for abrasive geological conditions, hard soil, cobble layers, and rock formations where superior wear resistance is required.
As part of the Wear-Resistant Rotary Drilling Teeth series, the 30606L-19 features a reinforced Ø60mm wide head design combined with circumferential hardfacing protection to minimize steel body erosion and extend operating life.
Built with a standard Ø30mm shank system and Ø38mm step collar, this rotary drilling tooth features a 75mm gauge length and 135mm overall length, providing excellent cutting clearance and stable drilling performance.
The tooth integrates a sharp-point Ø19mm tungsten carbide insert with multiple circumferential hardfacing wear-resistant rings around the conical head. This design effectively protects the carbide seat and steel body against abrasive cutting wear while maintaining efficient rock penetration.
Manufactured from precision drop-forged 42CrMo alloy steel, the 30606L-19 delivers excellent toughness, wear resistance, and reliable performance for foundation drilling contractors working in demanding ground conditions.

Key Features & Performance Advantages
1. Ø60mm Wear-Resistant Reinforced Head Design
The enlarged Ø60mm head structure provides additional steel protection around the carbide insert area.
This reinforced design helps:
- Improve wear resistance
- Protect the carbide mounting area
- Reduce steel body erosion
- Maintain stable drilling performance
The wide head design is especially suitable for continuous drilling operations in abrasive formations.
2. Ø19mm High-Performance Tungsten Carbide Tip
The sharp-point Ø19mm tungsten carbide insert provides concentrated cutting force for efficient penetration.
The optimized carbide design delivers:
- Excellent wear resistance
- Stable cutting performance
- Strong impact durability
- Reduced carbide chipping
It is suitable for:
- Weathered rock
- Cobble layers
- Dense soil
- Abrasive geological formations
3. Circumferential Hardfacing Wear Protection
The key feature of the 30606L-19 is the circumferential hardfacing ring protection applied around the conical head.
The wear-resistant overlay creates a protective barrier against:
- Steel wash caused by abrasive cuttings
- Surface erosion
- Premature body wear
- Carbide seat damage
This significantly extends tooth service life and reduces replacement frequency.
4. Optimized 75mm Gauge Length
The 75mm gauge length with 135mm overall length provides an ideal balance between cutting clearance and structural stability.
Advantages include:
- Improved chip evacuation
- Reduced cutting resistance
- Better drilling efficiency
- Stable operation in continuous drilling cycles
5. Forged 42CrMo Steel Body with Self-Rotation
The tooth body is manufactured from drop-forged 42CrMo alloy steel and heat-treated to HRC 48-52.
The high-strength steel structure provides:
- Excellent toughness
- Strong bending resistance
- High fatigue strength
- Long operating life
Combined with standard Ø30mm holders, the 360° self-rotation design ensures:
- Uniform wear distribution
- Self-sharpening performance
- Consistent drilling efficiency
