Henglong T51 115mm Retrac Threaded Button Bit For High Precision Rock Drilling
Brand: Henglong | Origin: China
The Henglong T51 115mm Retrac Threaded Button Bit is a high performance rock drilling tool tailored for mining, infrastructure engineering, and geothermal drilling projects. Featuring standard T51 thread connection and 115mm drilling diameter, this retrac button bit delivers stable penetration speed, precise hole positioning, and outstanding rock adaptability, serving as a core durable component for all kinds of hard rock drilling operations.
Diversified Bit Face Design for All Rock Conditions
Henglong T-series threaded button bits adopt multiple face structures to match different rock hardness and working pressure scenarios, solving common drilling problems like hole deviation, slow cutting evacuation, and rapid bit wear:
Concave (Drop Center) Face: Ideal for medium hard and uniform rock formations. Effectively controls hole deviation and accelerates rock cuttings discharge, ensuring neat and standard drill holes for blasting and exploration drilling.
Convex Face: Optimized for low-air-pressure drilling of soft to medium hard rock. It reduces side button friction and minimizes component wear while maintaining efficient drilling speed, suitable for conventional civil engineering drilling tasks.
Double Gauge (Double-side Button) Face: Built for high pressure drilling on extremely hard rock. The dual side button structure strengthens wear resistance, maintains fast penetration rate, and extends continuous working time.
Flat Face: Professional for high abrasive and ultra hard rock drilling under high air pressure. It features stable drilling performance and low body loss, perfectly adapting to harsh mining working conditions.
Retrac Structure Design & Working Principle
This T51 115mm retrac threaded bit adopts an integrated structure with cutting end and thread mounting end. Multiple spiral chip evacuation grooves are evenly distributed on the bit outer wall. During operation, the drilling rig rotates and advances synchronously, while high pressure air blows rock debris out through the grooves. This circulating airflow design realizes smooth and clean cuttings evacuation, avoids hole blockage, and greatly improves overall drilling efficiency.
Wide Industrial Application Scenarios
Engineered for versatility and reliability, the T51 115mm retrac button bit covers mainstream drilling fields worldwide:
Mining Drilling : Precisely drills standard blast holes and exploration holes, optimizes explosive utilization, achieves uniform rock fragmentation, and supports safe and efficient mineral resource exploration and mining.
Civil & Infrastructure Drilling : Applicable to water well drilling, geothermal drilling, foundation construction and environmental survey drilling. It adapts to complex underground rock layers and guarantees construction precision.
Core Product Advantages
High Drilling Efficiency : Optimized carbide button profile greatly improves penetration speed and deep drilling capability, effectively shortens project construction cycles.
Full Rock Adaptability : Works stably from soft rock to ultra hard abrasive rock, meeting diverse drilling demands of different geological environments.
Ultra High Drilling Precision : Precision machining technology controls hole deviation strictly, ensuring accurate hole positioning for high standard engineering projects.
Superior Durability & Cost Performance : Wear resistant bit body and high strength carbide buttons resist extreme drilling friction and impact, reduce frequent replacement and maintenance costs, and lower project downtime.
