Introduction: What Are Rock Bullet Drill Bits?
Rock bullet drill bits are heavy-duty cutting tools used for drilling into hard rock surfaces such as granite, basalt, and limestone. Fitted with tungsten carbide tips, these bits are engineered for high impact, abrasion resistance, and long service life in trenching, piling, HDD (Horizontal Directional Drilling) and tunneling applications.
In this guide, we’ll cover the types, applications, prices, and tips on selecting the right rock bullet drill bits for your next project.
Applications of Rock Bullet Drill Bits
These bits are commonly used in:
- Piling and foundation drilling
- Trenching and tunneling operations
- Micro-tunneling and HDD rigs
- Mining and rock excavation
Engineered for extreme conditions, rock bullet drill bits ensure high penetration rates and low tool wear, even in abrasive and fractured rock formations.
Types of Rock Bullet Drill Bits
1. Conical Bullet Bits
- Ideal for high-penetration drilling
