Product Overview
The 6-tooth, 11-degree, 43mm×69mm button bit is a high-efficiency rock drilling tool engineered for 11° tapered connections. Featuring a 43mm drilling diameter and 69mm length, this bit's 6 carbide button teeth are strategically arranged to optimize both penetration efficiency and impact resistance. Compatible with H22 11° tapered drill rods, it is primarily designed for medium-hard to hard rock drilling in deep hole applications, including mining tunnels, quarry blasting operations, and tunnel pre-support drilling.
Key Performance Features
Low Downtime Operation
The optimized 6-tooth design concentrates and evenly distributes cutting forces, effectively reducing drill bit jamming and hole blockage. Suitable for continuous operation in medium-hard rock formations, a single drill bit can reliably complete 80-100 standard anchor bolt holes, significantly reducing bit change frequency and supporting efficient project progress.
High Impact Resistance
Precision-forged from 42CrMo alloy steel with double heat treatment, achieving HRC 40-45 hardness and excellent fatigue resistance. Carbide ball teeth manufactured from YK05 material are securely fixed using hot-setting technology, enabling them to withstand frequent impact loads and delivering service life far exceeding ordinary drill bits of similar specifications.
