Product Description
 
  • Versatile Application Across Precision Machining

    Engineered with high-speed steel (HSS) for excellent hardness and wear resistance, these center drill bits are ideal for precise metal lathe operations. Whether you're working with aluminum, brass, mild steel, or alloyed metals, they deliver clean, sharp entry holes with minimal burrs-crucial for high-accuracy drilling, tapping, or reaming.

     

    Multi-Diameter Drilling with Integrated Deburring

    Designed with a stepped profile, each drill allows for multiple hole sizes to be created with a single tool. The smooth transitions between steps and built-in deburring action ensure consistently clean, professional-grade results, reducing the need for secondary processing and enhancing productivity in batch operations.

     

    Heat-Treated for Extended Life and Sharpness

    Each drill bit is vacuum heat treated to optimize both surface hardness and internal toughness. This ensures excellent thermal resistance and edge retention, making them perfect for high-speed, high-temperature applications such as repetitive lathe work and long-cycle manufacturing.

     

    Ideal for Industrial and DIY Use

    These center drills combine industrial-grade performance with ease of use, making them suitable for machinists, metal fabricators, toolmakers, and advanced hobbyists alike. From tooling setups to part manufacturing, they provide accurate centering and clean cuts that elevate your machining precision and finish quality.

Detailed Advantages

1. Razor-Sharp Cutting Edge for Effortless Entry

Manufactured from high-speed steel (HSS) and precision-ground for accuracy, these center drill bits deliver sharp, clean entry points with minimal effort. Their razor-sharp edges reduce cutting resistance and prevent burring, ensuring precise, clean holes that are essential for smooth downstream machining.

2. Self-Centering Split Point for Quick, Accurate Starts

Equipped with a split point tip, these drills eliminate the need for pre-punching and provide walk-free starts, even on curved or hard metal surfaces. This feature ensures maximum control and perfectly centered holes-critical for high-speed, high-precision drilling tasks.

3. Step-by-Step Chip Evacuation for Smooth Performance

The spiral flute design paired with stepped cutting geometry enables efficient chip evacuation at every stage. This minimizes heat buildup and prevents clogging, ensuring smoother operation and longer tool life, particularly in continuous or high-RPM lathe operations.

4. Corrosion-Resistant, Durable Finish

Each drill is finished with a polished or PVD-coated surface (e.g., TiN or TiCN), enhancing resistance to wear, rust, and lubricant corrosion. This ensures long-term performance consistency, especially in challenging industrial or moisture-prone environments.

Why Choose Our Product?

1. High-Efficiency Performance with HSS Technology

Crafted from premium-grade high-speed steel (HSS), these center drills are built to handle the heat, pressure, and wear generated during high-speed metal lathe operations. Their superior hardness and heat tolerance help maintain cutting-edge sharpness and structural strength, even during prolonged use on stainless steel, aluminum, and alloyed metals.

 

2. Clean, Multi-Diameter Drilling Without Tool Changes

With a precision-stepped geometry, each drill allows for multiple hole sizes in one tool. This not only simplifies the drilling process but also ensures clean, burr-free holes, eliminating the need for secondary finishing. The result: faster workflows and consistent quality, especially in high-throughput machining environments.

 

3. Versatile, Professional-Grade Design for Every Application

From industrial metalworking and automotive fabrication to custom tooling and DIY projects, these center drills offer stable, accurate, and repeatable results. Their carefully engineered balance and control make them ideal for creating precise centers for drilling, tapping, or reaming, enhancing both productivity and machining precision across applications.

Our Advantages

CNC Precision Grinding for Consistent Accuracy

Each HSS center drill bit is crafted using CNC precision grinding, delivering uniform step geometry, razor-sharp edges, and exact tip centering. This precision ensures clean, chatter-free drilling in metal lathe applications, with minimal vibration and maximum control-even at high spindle speeds.

 

Vacuum Heat Treatment for Long-Term Performance

Our drills undergo vacuum heat treatment to enhance both surface hardness and internal toughness, enabling exceptional resistance to wear, deformation, and thermal fatigue. Ideal for use on stainless steel, aluminum, and other hard metals, these bits remain sharp and stable under continuous high-load operation.

 

Ultra-Fine Polishing for Clean Finishes

A mirror-finished surface reduces friction and heat generation, while improving chip evacuation during deep or repetitive drilling cycles. This polished finish also prevents workpiece damage, especially when machining softer metals or thermoplastics-delivering cleaner, sharper cuts.

 

Refined Metallurgy & Thermal Optimization

High-Purity Steel via EAF + LF + VD + RS-ESR

Our HSS center drills are produced using a multi-stage steelmaking process including Electric Arc Furnace (EAF), Ladle Refining (LF), Vacuum Degassing (VD), and Electro-Slag Remelting (ESR) with rapid solidification. This ensures low impurity content, improved durability, and high performance in precision drilling.

Integrated Thermal Hardening Process

A combination of quenching, cryogenic treatment, and precision tempering increases hardness up to HRC 67, while maintaining ductility to resist chipping. This guarantees reliable operation under high-speed, high-pressure lathe drilling common in automotive, aerospace, and tooling industries.

RS-ESR Edge Stability Technology

Using Rapid Solidification ESR, the drill edge is reinforced with a uniform microstructure of carbides and cobalt-boosting wear resistance, thermal stability, and edge retention, especially in long-cycle or demanding machining conditions.

 

Customizable Engineering for Application Flexibility

Material Options: M35-Centric Design

While M2 and M42 are available, we recommend M35 HSS for its optimal hardness-to-toughness ratio, ensuring excellent wear resistance and cutting edge stability in lathe work, particularly when drilling abrasive or high-strength materials.

Custom Step Geometry and Coatings

Available with tailored flute lengths, helix angles, and step sizes, our drills can be configured for specific applications. Optional PVD coatings such as TiN, TiAlN, or TiCN enhance tool life by improving resistance to heat, wear, and friction in aggressive cutting environments.

 

Design Innovations for Lathe Efficiency

Optimized Multi-Step Chip Flow

The flute spacing between steps is carefully engineered to enable smooth chip evacuation, preventing clogging and minimizing heat accumulation. This supports stable, high-RPM drilling, particularly in thin sheet metals or thermoplastics.

Precision-Cut Step Angles for Smooth Entry

Cutting angles and step transitions are tuned to reduce axial force and material deformation, especially in thin-walled or soft metals. The result: stable drilling with clean entry points and crisp finishes.

Application-Specific Coating Solutions

For high-performance requirements, drills can be coated with TiAlN for high-temperature lathe work or TiCN for enhanced wear protection. These coatings extend tool life and enable reliable, multi-diameter performance in complex or automated machining lines.
