R32-45mm Threaded Button Bit
Premium Rock Drilling Tool Engineered for High-Efficiency Tunneling, Mining, and Quarrying Operations
Product Overview
The R32-45mm Threaded Button Bit is a premium rock drilling tool engineered for high-efficiency drifting, tunneling, and underground bench drilling. Manufactured from high-grade alloy steel and ultra-wear-resistant tungsten carbide inserts (spherical or ballistic buttons), this 45mm drill bit delivers maximum impact energy transfer, fast penetration rates, and extended operational lifespan in medium to hard rock formations.
Designed with a Flat Face (FF) and optimized flushing hole configuration, it ensures superior hole straightness, efficient cuttings evacuation, and reduced wear on the drill string, making it an ideal choice for modern hydraulic rock drills.
Main Applications
Underground Tunneling & Drifting
Precision hole drilling for tunneling projects and mine development operations.
Rock Bolting & Anchoring
Fast drilling for roof support installation in mining and civil engineering.
Dimensional Stone Quarrying
Clean and straight hole drilling in granite, limestone, and marble quarries.
Bench Drilling
Small-hole benching and production drilling in open-pit or underground mining.
Key Features & Advantages
Superior Carbide Quality
Premium tungsten carbide buttons offer high impact resistance and exceptional resistance to abrasive wear, ensuring longer service life in demanding conditions.
Advanced Thermal Insertion Technology
Carbide inserts are hot-pressed into CNC-machined body sockets to prevent button dropouts during high-impact drilling operations.
Optimized Flushing System
Strategically placed front and gauge flushing holes facilitate rapid removal of rock debris, preventing bit re-drilling and overheating.
High Energy Transfer
Designed for seamless compatibility with R32 drifter rods and standard hydraulic rock drills from major manufacturers.
Cost-Effective Performance
Delivers lower cost-per-meter drilling through extended service intervals and excellent wear resistance in medium to hard rock formations.
