Product Overview

The Impact-Resistant 14-Tooth T51 Threaded Button Bit is a high-efficiency rock drilling tool engineered for complex tunneling conditions. Designed with superior impact resistance and adaptability, this bit excels in medium-hard to extremely hard rock formations, significantly enhancing drilling stability and operational efficiency in demanding tunneling applications.

Key Features & Benefits

Enhanced Impact Resistance: 14 carbide ball teeth with 40% increased single-tooth impact strength withstand tunnel rock drilling loads, minimizing tooth breakage and loss
Precision Drilling: Central positioning tooth design ensures drilling accuracy within ±1mm for uniform tunnel blasting results
Optimized Tunnel Performance: Multi-water hole dust removal system coarsens rock cuttings and reduces dust concentration by 60%
Extended Durability: Maintenance-free ball teeth design provides 5-6 times longer service life than traditional flat drill bits, reducing replacement frequency and improving construction continuity
Versatile Rock Formation Compatibility: Universal face head handles uneven hardness and fractured rock formations, preventing drill bit jamming and borehole collapse
