R32 45mm Threaded Button Bit for Rock Drilling

The R32 45mm threaded button bit is a top hammer rock drilling tool engineered for high-efficiency drifting, tunneling and underground bench drilling. Manufactured from high-grade alloy steel with ultra-wear-resistant tungsten carbide inserts, this 45mm drill bit delivers efficient impact energy transfer, fast penetration rates and an extended service life in medium to hard rock formations.

Product Overview

Designed with a flat face (FF) profile and an optimized flushing hole configuration, the R32-45mm button bit ensures excellent hole straightness, efficient cuttings evacuation and reduced drill string wear. It is an ideal choice for modern hydraulic rock drills and R32 drifter rods.

Main Applications

Underground Tunneling & Drifting: Precision hole drilling for tunneling projects and mine development.
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 operations.

Key Features & Advantages

High-Grade Carbide Quality: Premium tungsten carbide buttons provide high impact resistance and excellent resistance to abrasive wear.
Advanced Thermal Insertion Technology: Carbide inserts are thermally pressed into CNC-machined body sockets to prevent button dropout during high-impact operations.
Optimized Flushing System: Strategically placed front and gauge flushing holes enable rapid removal of rock debris, preventing bit re-drilling and overheating.
High Energy Transfer: Seamless compatibility with R32 drifter rods and top hammer hydraulic rock drills.
Cost-Effective Performance: Lower cost per meter of drilling through extended service intervals and excellent wear resistance.
