The SDF-G Series General Purpose External Cooling 5D Solid Carbide Drill is a high-performance tool specifically designed for high-precision and efficient machining. Manufactured from high-quality micro-grain tungsten carbide, this product series ensures superior performance on hard materials such as hardened steel (HRC55°), making it ideal for various precision mold and component machining tasks.

Materials and Manufacturing Process

• High-Quality Micro-Grain Tungsten Carbide: The tools are crafted from high-quality micro-grain tungsten carbide stock, offering exceptional hardness and toughness. This material maintains stable cutting performance even under high temperature and pressure conditions, providing a durable and reliable machining experience.
• Advanced Grinding Technology: Utilizing advanced German WALTER five-axis grinding machines, the tools undergo precision grinding to achieve ultra-high accuracy in both cutting edge diameter and shank diameter. This ensures optimal geometric precision and surface quality, meeting the requirements for high-precision machining.

Design Features

• External Cooling System: The drill is equipped with an efficient external cooling system that ensures coolant is delivered directly to the cutting zone. This design not only provides superior cooling, extending tool life, but also significantly enhances machining accuracy and surface finish quality.
• Optimized Flute Design: The flute geometry is meticulously designed to optimize chip evacuation, ensuring smooth chip removal. This design minimizes issues such as chip clogging or overheating, thereby improving machining efficiency and reliability.
• Five-Diameter Length: The drill’s length is five times its diameter, providing excellent guidance and stability. This contributes to achieving precise drilling results while effectively reducing deflection and vibration, ensuring straightness and roundness in the drilled holes.

Coating Technology

• ALCRONA High-Wear Resistant Coating: The surface is coated with ALCRONA high-wear resistant coating, which significantly enhances the drill’s resistance to high temperatures and wear. This allows the drill to maintain superior performance when processing high-strength and hard materials, while also extending the tool’s service life and machining efficiency.

Application Methods

• Optimal Cutting Parameters: To maximize performance, it is crucial to select appropriate spindle speeds and feed rates based on the material being machined. For materials with hardness up to HRC 55, adhering to the manufacturer’s recommended values can prevent unnecessary wear or damage and ensure optimal machining outcomes.
• Proper Maintenance: Regular inspection of the drill is necessary to identify any visible damage or excessive wear. Proper storage away from corrosive substances and maintaining cleanliness and dryness are essential to prevent oxidation and other forms of degradation. Additionally, timely removal of chips during operation prevents secondary cutting damage to the drill.

Suitable Applications

• Automotive Manufacturing: Ideal for rapid drilling of cast iron, steel, and other hard materials (HRC ≤ 55). It excels in delivering efficient and high-quality drilling operations, particularly in applications requiring high precision and stability.
• Mold Making: When precision drilling of mold components is required, the SDF-G series drill performs exceptionally well, especially for high-strength materials.
• Electronics Industry: Suitable for micro-drilling in PCB boards, meeting the fine machining requirements of electronic products, particularly in high-precision and reliable micro-drilling applications.

Quality Assurance

• Strict Quality Inspection: Using German ZOLLER equipment for strict quality inspection ensures that each drill meets high-performance and stability standards, conforming to the requirements for high-precision machining.
