SHANDIKE Rock Drill Bits – Drill Steel & Rod Solutions
Product Overview
As a professional rock drilling tools manufacturer, SHANDIKE offers a comprehensive range of drilling components including drill bits, couplings, shank rods, and tunnel rods. Our products feature hexagon bodies (H25-H35) and round (39mm) configurations, available in standard lengths from 2440mm to 6435mm (8′-21′). Thread options include R25, R28, R35 bit-end threads with standard shank-end thread types. Male/female tunneling rods are available in both 35mm hexagon and 39mm round configurations.
Key Product Lines
1. Drifting Drill Rods (Hex 35)
– Structural Advantages:
– Hexagonal cross-section measured across flats (35mm)
– Enhanced rigidity and energy transfer efficiency
– Reduced annular space improves flushing effectiveness
– Turbulence generation via steel corners maintains cuttings movement (particularly effective in horizontal drilling)
– Enables larger thread configurations
2. Drifter Drill Steel (R32-T38)
– Rope Thread (R32):
– Low-pitch design (12.7mm) with shallow profile angle
– Sizes: 22-38mm
– High wear resistance with limited uncoupling capability
– Ideal for:
• Single-pass drilling
• Short-hole applications (e.g., underground tunneling)
• Operations requiring minimal uncoupling
– Note: Not recommended for extension drilling with high-torque drills
– T-Thread (T38):
– HM/T-thread configuration with increased pitch and profile angle
– Sizes: 38/45/51mm
– Combines superior wear resistance with reliable coupling
– Optimal for:
• Multi-rod extension drilling
• High-torque applications (surface & underground)
Technical Features
– Enhanced Strength Design: Drive-end reinforcement accommodates larger diameter shank adapters
– Compatibility: Standard lengths match feed systems on most drifting jumbos
– Hole Accuracy: Close bit-to-steel diameter ratio improves flushing and precision
