Product Overview

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.

Main Applications

Quarrying

Bench drilling, stone quarry drilling, and production hole drilling operations.

Mining

Surface mining, underground mining, and blast-hole preparation.

Tunneling

Tunnel excavation, development drilling, and face drilling projects.

Construction & Infrastructure

Foundation drilling, slope stabilization, road cutting, and dam construction.

Trenching

Pipeline trenching, utility installation, and rock trench drilling.

Hydropower Projects

Dam construction, water tunnel drilling, and rock excavation.

Key Features & Advantages

T45 Thread Connection

Compatible with T45 drill rods, coupling sleeves, and shank adapters for standard hydraulic drilling systems.

Retrac Skirt Design

Helps improve guidance and supports bit withdrawal from fractured or unstable rock formations.

Wear-Resistant Carbide Buttons

Designed to resist impact and abrasive wear during rock drilling, with spherical and ballistic profiles available.

Efficient Flushing System

Front flushing holes support effective removal of dust and rock cuttings, reducing repeated grinding and improving penetration rate.

Heat-Treated Alloy Steel Body

Provides structural strength and durability for repeated impact drilling operations in demanding rock conditions.

Customizable Configuration

Face design, button layout, flushing holes, carbide grades, and surface color can be adjusted according to project requirements.
