Precision in Rock Drilling for Mining Excellence

Key Features:

• Hexagonal Chuck Section: Provides leverage for the rotation chuck bushing.
• Forged Collar: Maintains the proper shank striking face position in the rock drill.
• Wide Taper Angles (11o and 12o): Ideal for high impact hydraulic rock drills in medium to hard and abrasive rock formations.
• Narrow Taper Angle (7o): Suitable for low impact rock drills and softer rock formations.
• Special Taper Angle (4.8o): Prevents bit spinning or detachment in soft rock using pneumatic or hydraulic drill rigs.
• Single Rod and Series Rods: Choose based on drilling depth to avoid bending stress excess.

Taper Rods Grades Recommended:

1. Superior Grade: Rock drills impact energy ≥76J, drilling depth ≥2.5m, suitable for very hard, hard, medium hard, and soft rock formations.
2. Normal Grade: Rock drills impact energy <76J, drilling depth ≤2.5m, suitable for medium-hard and soft rock formations.
3. Economy Grade: Rock drills impact energy <76J, drilling depth ≤2.5m, suitable for medium-hard and soft rock formations with lower hardness.
