Advanced Hydraulic Rock Drilling Tool for Quarrying, Mining, Tunneling, and Construction Operations
The T45 76mm Retrac Thread Button Bit is designed for hydraulic rock drilling operations requiring stable drilling performance and effective hole cleaning. It features a T45 threaded connection, a 76mm bit diameter, and a retrac-style skirt suitable for demanding drilling conditions in medium-hard to hard rock formations.
The bit body is manufactured from selected alloy steel and fitted with wear-resistant carbide buttons. Its front flushing holes help remove rock cuttings from the borehole, reduce repeated grinding of cuttings, and support efficient drilling. The retrac skirt provides additional guidance and assists with bit withdrawal in fractured or unstable rock formations.
Bench drilling, stone quarry drilling, and production hole drilling operations.
Surface mining, underground mining, and blast-hole preparation.
Tunnel excavation, development drilling, and face drilling projects.
Foundation drilling, slope stabilization, road cutting, and dam construction.
Pipeline trenching, utility installation, and rock trench drilling.
Dam construction, water tunnel drilling, and rock excavation.
Compatible with T45 drill rods, coupling sleeves, and shank adapters for standard hydraulic drilling systems.
Helps improve guidance and supports bit withdrawal from fractured or unstable rock formations.
Designed to resist impact and abrasive wear during rock drilling, with spherical and ballistic profiles available.
Front flushing holes support effective removal of dust and rock cuttings, reducing repeated grinding and improving penetration rate.
Provides structural strength and durability for repeated impact drilling operations in demanding rock conditions.
Face design, button layout, flushing holes, carbide grades, and surface color can be adjusted according to project requirements.
We offer tailored button layouts, carbide grades, face designs, and flushing configurations to match your specific rock conditions and drilling equipment. Contact us today for a customized solution.
