Product Overview
The BF72 Flat Cutting Tooth is a high-performance rotary drilling bucket tooth engineered for foundation piling, deep trenching, excavation, and challenging ground drilling applications.
Designed as a durable replacement component for heavy-duty drilling equipment, the BF72 is widely installed on:
- Rotary drilling buckets
- Rock core barrels
- Cleaning buckets
- Diaphragm wall trenching grabs
- Foundation drilling attachments
Manufactured from premium forged alloy steel, the BF72 features strategically positioned tungsten carbide (TC) inserts along the cutting edge to provide outstanding wear resistance, impact toughness, and extended service life in abrasive geological conditions.
With its optimized 72mm flat blade cutting profile, the BF72 delivers efficient material removal, stable cutting performance, and reduced drilling resistance, making it an ideal solution for contractors working in gravel, weathered rock, sandstone, and mixed ground formations.
Key Advantages and Operational Benefits
1. Multi-Point Tungsten Carbide Protection
The BF72 features a high-density tungsten carbide reinforcement system embedded along the cutting edge.
The carbide protection design helps:
- Prevent premature steel body wear
- Improve abrasion resistance
- Maintain sharp cutting performance
- Extend tooth replacement intervals
- Reduce operating costs
This reinforced cutting edge provides reliable performance in abrasive soils, gravel layers, and weathered rock formations.
2. Optimized 72mm Flat Blade Geometry
The 72mm wide flat cutting profile is engineered to achieve an ideal balance between cutting efficiency and drilling torque requirements.
Advantages include:
- Improved soil and rock scraping performance
- Higher rate of penetration (ROP)
- Reduced drilling resistance
- Lower energy consumption
- Improved bucket filling efficiency
The optimized geometry helps maintain stable drilling performance while reducing equipment load during continuous operations.
3. Secure Locking System and Easy Replacement
The BF72 is manufactured with precision shank dimensions and an optimized retaining groove system to ensure reliable installation.
Benefits include:
- Secure tooth positioning
- Reduced risk of tooth loss during drilling
- Faster field replacement
- Reduced equipment downtime
- Improved jobsite efficiency
The reliable locking design ensures stable operation during deep foundation drilling and trenching applications.
4. High Impact Resistance Alloy Steel Body
The BF72 tooth body is manufactured from heat-treated forged alloy steel to provide superior mechanical strength.
The durable construction delivers:
- Excellent impact resistance
- High fatigue strength
- Improved crack resistance
- Superior toughness under heavy loads
- Longer service life
This makes the BF72 suitable for applications involving boulders, hard gravel, and weathered rock layers.
