Our Advantages

CNC Precision Grinding for Maximum Accuracy

Our HSS center drill bits are manufactured using CNC precision grinding to achieve uniform step heights, razor-sharp cutting edges, and accurate tip centering. This precision ensures clean, accurate drilling for creating centers in metal parts with minimal vibration and maximum stability, even during high-speed lathe operations. The result is improved precision and efficiency for your machining tasks.

 

Vacuum Heat Treatment for Enhanced Durability

To ensure long-lasting performance, each center drill bit undergoes vacuum heat treatment, which increases both surface hardness and core toughness. This advanced treatment enhances resistance to wear and heat, making these bits perfect for drilling through tough materials like stainless steel, aluminum, and other metals. This ensures a long service life under demanding lathe conditions.

 

Ultra-Fine Polishing for Smoother Drilling

The ultra-fine polished surface of our drill bits reduces friction, improves chip evacuation, and minimizes heat generation during deep or repetitive drilling. This polishing treatment also protects both the drill bit and the workpiece surface, preventing surface damage, especially when drilling soft metals or thermoplastics. The smoother surface ensures better performance and longer tool life.

 

Refined Metallurgy & Thermal Optimization

1. Advanced Steel Purification for Maximum Toughness

Our center drill bits are made from ultra-clean high-speed steel (HSS) through advanced metallurgical processes such as Electric Arc Furnace (EAF), Ladle Refining (LF), Vacuum Degassing (VD), and Electro-Slag Remelting (ESR). This purification process reduces impurities, enhancing toughness and reliability for drilling through hard metals and layered composites.

2. Integrated Thermal Optimization for Superior Hardness

A combination of quenching, cryogenic treatment, and precision tempering enhances hardness to HRC 67, while maintaining resistance to chipping and cracking. This makes our drill bits highly reliable under the high-speed, high-pressure drilling conditions typical in precision lathe work, automotive, and fabrication industries.

3. RS ESR Edge Enhancement Technology for Long-Lasting Performance

Through Rapid Solidification ESR processing, the cutting-edge structure is reinforced with uniformly distributed carbides and cobalt, enhancing edge retention and wear resistance. This ensures reliable performance in high-temperature, high-load lathe operations, making these drill bits ideal for demanding industrial environments.
