Product Description

Product Description

Our specialized drifting and tunneling tools are meticulously categorized by thread types: R25, R28, and R32. These threads are tailored to suit the distinct diameters of your drilling rods, providing precision and efficiency.
For each thread variant, we offer an exceptional range of products such as drill bits, drill rods, shank adapters, and couplings, all engineered for peak performance.

1. Drill Bit:

a. Classification: Our drill bits are expertly classified into button bits, reaming bits, and cross-type bits, with the robust button bit being the primary choice.
b. Material: Constructed from high-grade hot-set steel such as FF710 and 45CrNiMoVA, our drill bits are embedded with YK05 alloy using an advanced hot-set technique.
c. Alloy Shape: Choose from a selection of alloy shapes including spherical, parabolic, and ballistic buttons. The parabolic button is optimal for rapid penetration, while the spherical button excels in high wear-resistance applications.

2. Drill Rod:

a. Classification: Distinguished by structure, our drill rods are available as extension rods and speedrods. Hexagonal drill rods are predominantly used for drifting and tunneling tools.

b. Material: Manufactured from premium 23CrNi3Mo, our drill rods undergo a superior carburizing treatment for enhanced durability and strength.

3. Shank Adapter and Coupling: Crafted from 23CrNi3Mo and treated through an advanced carburization process, ensuring reliable performance.
