Henglong 37mm Diameter R25 Interface Connector Sleeve for Rock Drilling & Blast Furnace Opening
This professional drill bit connection component features a 37mm diameter with R25 standard thread interface, specifically engineered for rock drilling equipment, blast furnace opening machines, and metallurgical drill bits. It ensures stable connection between drill rod and drill bit for efficient torque transmission.
Connector Sleeve Types
Rock drilling connecting sleeves are categorized into four main types: full-bridge connecting sleeves, half-bridge connecting sleeves, equal-diameter connecting sleeves, and variable-diameter connecting sleeves.
Premium Construction
Manufactured from high-strength alloy steel with deep heat treatment (quenching + tempering), featuring exceptional tensile strength, impact resistance, vibration resistance, anti-slip properties, compact structure, direct force transmission, low energy loss, and easy assembly/disassembly.
Key Advantages
High Strength & Impact Resistance: Made from premium alloy steel with professional heat treatment for impact resistance, fatigue resistance, and durability
Stable Connection & Non-Slippage: High thread precision and tight fit ensure stable transmission of torque and impact force without loosening
High Force Transmission Efficiency: Optimized structural design minimizes energy loss for faster, more efficient drilling
Easy Assembly & Strong Versatility: Quick connection of drill rods and shanks; compatible with both same-diameter and variable-diameter drills across various drilling rigs
Wear-Resistant & Durable: Wear-resistant surface and threads extend service life while reducing operating costs
Harsh Condition Performance: Suitable for high-load, long-term operation in mining, tunneling, and engineering projects with exceptional stability
Application Areas
Ideal for rock drilling operations, blast furnace opening applications, metallurgical drilling, mining operations, tunnel construction, and heavy engineering projects requiring reliable, high-performance drill connections.
