Our Advantages

CNC Precision Grinding
Our high-performance HSS center drill bits are crafted using CNC precision grinding to ensure uniform step heights, razor-sharp cutting edges, and precise tip centering. This level of precision guarantees clean and accurate drilling, allowing for the creation of centers in diamond cutting operations with minimal vibration and maximum stability, even during high-speed lathe tasks.

Vacuum Heat Treatment
To maximize tool longevity, each center drill bit undergoes vacuum heat treatment, enhancing both surface hardness and core toughness. This treatment improves wear and heat resistance, making these bits ideal for drilling through tough materials like stainless steel, aluminum, and other metals, ensuring they perform reliably over time under the most demanding diamond cutting conditions.

Ultra-Fine Polishing
The ultra-fine polished surface of our center drill bits reduces friction, improves chip removal, and minimizes heat generation during deep or repetitive diamond cutting operations. This polishing treatment also helps protect the drill bit and the workpiece, preventing surface damage, particularly when working with soft metals or thermoplastics, ensuring clean, flawless results every time.

 

 

Refined Metallurgy & Thermal Optimization

Advanced Steel Purification: EAF + LF + VD + RS ESR
Our high-performance HSS center drill bits are crafted from ultra-clean high-speed steel (HSS) through advanced metallurgical processes, including Electric Arc Furnace (EAF), Ladle Refining (LF), Vacuum Degassing (VD), and Electro-Slag Remelting (ESR). This purification process reduces impurities, enhancing toughness and reliability, which is essential for precision diamond cutting through hard metals and layered composites.

Integrated Thermal Optimization
Through a combination of quenching, cryogenic treatment, and precision tempering, our center drill bits achieve a hardness of HRC 67 while maintaining exceptional resistance to chipping and cracking. This thermal optimization ensures the bits remain highly reliable during high-speed, high-pressure diamond cutting, making them perfect for demanding lathe operations in the precision machining and fabrication industries.
