Product Description

Product Description

 

Delve into the world of top-notch drifting and tunneling tools, meticulously categorized into R25, R28, and R32 based on thread specifications. These are further refined according to the diverse diameters of the drilling rods, offering you three distinct threading options to meet your varying needs.
Each thread category showcases a comprehensive selection of essential components, including drill bits, drill rods, shank adapters, and couplings, ensuring seamless compatibility and exceptional performance.

1. Drill Bit:

a. Classification: Our drill bits are expertly classified into button bits, reaming bits, and cross-type bits. Among these, the button bit stands out as the quintessential choice for efficiency and effectiveness.
b. Material: Crafted with precision, the body is forged from superior hot-set steel, such as FF710 and 45CrNiMoVA, while the alloy primarily consists of YK05, utilizing an advanced hot-set inlay process.
c. Alloy Shape: Our alloys are meticulously shaped into spherical buttons, parabolic buttons, and ballistic buttons. Choose parabolic buttons for swift penetration, while spherical buttons are ideal for high wear resistance, tailored to your specific working conditions.

2. Drill Rod:

a. Classification: Designed for versatility, drill rods are categorized into extension rods and speedrods, based on structural types. For drifting and tunneling, hexagonal drill rods are the go-to choice, ensuring stability and performance.

b. Material: Our drill rods are typically made from 23CrNi3Mo, enhanced with a precise carburizing treatment for lasting durability and strength.

3. Shank Adapter and Coupling: Manufactured from high-grade 23CrNi3Mo, these components undergo meticulous carburization, ensuring they stand the test of time with uncompromising integrity.
