Product Overview
The 3050CF-19 Wear-Resistant Fluted Rotary Drilling Bullet Tooth is an advanced foundation drilling wear part engineered for highly abrasive soil, heavy sand conditions, sticky clay formations, and challenging ground applications.
Also known as a fluted piling tooth or fast-clearing rotary drilling tooth, the 3050CF-19 features a unique longitudinal flute design on the conical head, improving cutting discharge efficiency and reducing material buildup during continuous drilling operations.
Built with a standard Ø30mm shank, a maximum head diameter of Ø50mm, and an extended 80mm gauge length, this rotary drilling tooth provides excellent clearance, faster penetration, and improved wear resistance.
The combination of a high-toughness Ø19mm tungsten carbide insert, forged 42CrMo alloy steel body, and anti-wear fluted design delivers reliable performance in abrasive formations while helping reduce downtime and replacement costs.
Designed for professional foundation drilling contractors worldwide, the 3050CF-19 is an ideal solution for rotary drilling rigs, rock augers, drilling buckets, and deep foundation construction projects.

Key Features & Performance Advantages
1. Longitudinal Fluted Anti-Wear Design
The 3050CF-19 features specially engineered longitudinal flutes (grooves) along the conical head.
During rotation, these channels help:
- Improve rock cutting and soil discharge
- Reduce debris accumulation
- Minimize slurry buildup
- Decrease steel body abrasion
The fluted body design improves drilling efficiency, especially in:
- Sandy formations
- Sticky clay
- Gravel layers
- Abrasive soil conditions
2. Extended 80mm Gauge Length for Improved Clearance
The extended 80mm gauge length provides greater tooth exposure compared with standard rotary drilling teeth.
Advantages include:
- Improved cutting clearance
- Deeper penetration per rotation
- Reduced drilling resistance
- Higher drilling efficiency
The 140mm overall length design helps optimize performance in deep foundation applications.
3. High-Toughness Ø19mm Tungsten Carbide Insert
Equipped with a premium Ø19mm tungsten carbide tip, the 3050CF-19 provides excellent impact resistance and wear durability.
The optimized carbide grade delivers:
- High fracture toughness
- Strong impact absorption
- Reduced carbide chipping
- Long operating life
It ensures stable cutting performance under continuous rotary drilling conditions.
4. Forged 42CrMo Alloy Steel Body
The tooth body is manufactured from forged 42CrMo alloy steel and precision heat-treated to HRC 48-52.
The high-strength steel structure provides:
- Excellent bending resistance
- Superior shear strength
- Strong fatigue durability
- Reliable performance under high torque
5. 360° Self-Rotating & Self-Sharpening Performance
Designed for standard Ø30mm rotary drilling tooth holders, the 3050CF-19 allows smooth 360° rotation during operation.
The self-rotating design provides:
- Uniform wear distribution
- Continuous self-sharpening effect
- Stable penetration performance
- Extended tooth service life
