China R38 Drill rod Factories, Pricelist

Male/Female(M/F)Rod-Speed rod M/F drill steel is an alternative to couplings sleeves to include the female part of the threaded connection as an integral part of the drill steel. M/F drilled steel provides a stronger connection and is easier to remove. The service life also tends to be better than with separate couplings.

Extension rod, other names are Extension drill steel, Extension drill rod, and Extension steel.

Product Description

Bench and production drilling tools include rods, shank adapters, couplings and bits. We offer 10 major thread types: R3212, R32, HL38, T38, T45, T51, T60, ST58, GT60, and ST68. These high-performance components are designed for seamless use with button bits, cross bits, and reaming products.

Our comprehensive range of rock drilling tools covers everything from 1” rope thread equipment up to T60 thread equipment. These drill rods, tubes, and button bits are engineered to improve site productivity considerably.

Product Features & Advantages

Male/Female (M/F) Rods: M/F drill steel serves as an efficient alternative to coupling sleeves. By integrating the female part of the threaded connection directly into the drill steel, M/F rods provide a stronger connection and are easier to remove. The service life is significantly improved compared to separate couplings.

Extension Rods: Also commonly referred to as Extension drill steel or Extension drill rods.

Frequently Asked Questions

What are the main advantages of M/F (Male/Female) drill rods?

M/F rods integrate the female connection as part of the drill steel, providing a stronger connection that is easier to remove and typically offers a longer service life than separate coupling sleeves.

What steel material is used for the T35 drill rod?

The T35 drill rod is manufactured using high-quality Sanbar 64 steel for maximum durability and performance.

Which thread types are available in your bench drilling range?

We provide 10 standard thread types: R3212, R32, HL38, T38, T45, T51, T60, ST58, GT60, and ST68.

How does the carburizing process help the production tools?

The overall carburizing process hardens the surface of the steel while maintaining core toughness, which significantly increases resistance to wear and fatigue.

What are the available length options for these drilling rods?

Standard lengths range from 600mm to 4270mm, catering to various bench and production drilling requirements.

Are these rods compatible with different bit types?

Yes, our drilling tools are fully compatible for use with button bits, cross bits, and various reaming products.
