Product Description

Product Description

 

Our distinct drifting and tunneling tools are expertly categorized by thread sizes: R25, R28, and R32. These threads are meticulously matched with varying drilling rod diameters to ensure unparalleled performance.
Each thread variant boasts a comprehensive array of products including high-performance drill bits, robust drill rods, shank adapters, and reliable couplings, all designed to meet your drilling needs.

1. Drill Bit:

a. Classification: Our drill bits are expertly categorized into button bits, reaming bits, and the cross-type bits, with the revolutionary button bit taking the lead in popularity and performance.
b. Material: Crafted with precision, the drill body is composed of exceptional hot-set steel, such as FF710, 45CrNiMoVA. The alloy, predominantly YK05, is seamlessly integrated using the advanced hot-set inlay process.
c. Alloy Shape: Our alloys are expertly shaped into spherical buttons, parabolic buttons, and ballistic buttons. For rapid penetration, the parabolic button is ideal, while the spherical button is perfect for enhanced wear resistance.

2. Drill Rod:

a. Classification: Drill rods are systematically divided into extension rods and speedrods, each tailored for specific structural needs. Hexagonal drill rods are predominantly used in our drifting and tunneling tools.

b. Material: Our drill rods are crafted from the resilient 23CrNi3Mo, elevated through meticulous carburizing treatment for superior durability and performance.

3. Shank Adapter and Coupling: Constructed from high-quality 23CrNi3Mo, these components undergo precise carburization for enhanced strength and reliability.
