Description

This is a T45-D46-T45 3050mm Extension Rod we often make.

Rod Type: Extension Rod

Thread Type: T45 – T45

Rod Diameter: 46 mm

Length: 3050 mm

Material: High-grade alloy steel, heat-treated & carburized

This is a T45-D46-T45 3050mm extension rod we often make.

The T45-D46-T45 drill rod has 1830-4270mm options, such as (T45-D46-T45-1830mm; T45-D46-T45-3050mm; T45-D46-T45-3660mm; T45-D46-T45-4270mm; Round body from 32mm to 51mm(1 1/4inch to 2inch)

Features & Benefits:

Superior Strength: Heat-treated alloy steel for resistance to bending and breakage.

Optimized Threads: T45 threads provide secure connections and efficient energy transfer.

Extended Lifespan: Carburized surface for wear resistance in demanding drilling conditions.

Cost-Effective: Designed for fewer replacements and lower operating costs.

Applications:

Bench drilling in quarries

Underground mining & tunneling

Construction and rock excavation

Long-hole and production drilling

In addition, we can design and manufacture other types of drill rods according to customer requirements, such as, T38, T45, T51, GT60 drill rod; Extension Rod, Speed Rod, MF-Rod

Thread Type:

For Extension Drill Rod, there are R22, R25, R28, R32, R38, T38, T45, T51, ST58, GT60 threads, and different lengths of rods are available from 600mm to 6400mm.

Feature Of The ExtensionDrillRod MF Rod:

Drill rod using thread system. Drilling precision can be further improved by using this as the first rod in a normal drill string. Furthermore, since this is a speed rod design it will produce straighter holes and at least 10% higher penetration rate in good rock conditions compared to rod and coupling sleeve combination system.

Widely used in drifting, tunneling, benching, and long hole drilling

High strength chromium-molybdenum steel with high fatigue strength and excellent wear resistance
