Our Advantages

Advanced Manufacturing Capabilities

1. CNC Precision Grinding
   Each drill bit is crafted with CNC precision grinding to ensure consistently sharp flute geometry and optimized tip angles. This enables smooth and accurate drilling, even during high-speed, repetitive operations, ensuring superior performance with minimal vibration.

2. Vacuum Heat Treatment
   Our M35 cobalt drill bits undergo vacuum heat treatment to enhance both surface hardness and internal toughness. This process improves their durability and extends tool life, even in the most demanding applications where heat and friction are a concern.

3. Ultra-Fine Polishing
   A fine polishing process reduces friction and prevents chip adhesion, which improves heat dissipation. This minimizes the risk of overheating and protects workpiece surfaces during high-load drilling, contributing to both tool longevity and optimal results.

Refined Metallurgy & Material Purity

1. EAF + LF + VD + RS ESR Technology
   We utilize advanced production techniques like Electric Arc Furnace (EAF), Ladle Furnace (LF), Vacuum Degassing (VD), and Rapid Solidification (RS) Electro Slag Remelting (ESR) to produce high-quality, high-toughness M35 cobalt steel. This reduces internal impurities and brittleness, ensuring improved reliability under both thermal and mechanical stress.

Integrated Thermal Optimization

1. Quenching + Cryogenic Treatment + Tempering
   Our advanced heat treatment process-comprising quenching, cryogenic treatment, and tempering-optimizes the hardness of the material up to HRC 67. This process ensures the preservation of structural integrity and crack resistance, which is crucial for maintaining tool performance in tough metal drilling applications.

RS ESR Advanced Edge Enhancement

1. Rapid Solidification ESR
   This technology refines carbide and cobalt particle distribution, enhancing the cutting edge's ability to resist heat softening and wear during deep or high-speed drilling. This increases the longevity and efficiency of the bit during demanding tasks.

Customizable Engineering Options

1. M35-Centric Configuration
   While M2 and M42 cobalt options are available, this selection is centered on M35 for its superior wear resistance, particularly suited for drilling stainless steel and high-strength alloys. M35's enhanced toughness makes it the optimal choice for challenging materials.

2. Tailored Geometry & Coatings
   Customization options include specific flute lengths, helix angles, and advanced PVD coatings (such as TiN, TiAlN, etc.), which are tailored for increased durability, better chip evacuation, and improved performance in material-specific applications.

Key Design Adaptations for M35 Twist Drills
