Baildon HSS-E Co5 Stainless Steel Twist Drill Bit DIN 338 RN NWKa 4.8 mm

The Baildon 4.8 mm HSS-E Co5 twist drill bit is a high-performance cutting tool designed specifically for demanding metalworking tasks. Manufactured according to DIN 338 standards, this drill bit features a 5% cobalt alloy composition, which significantly enhances its heat resistance and structural integrity when drilling into tough materials. The precision-engineered NWKa geometry facilitates smooth operation and reliable chip evacuation, ensuring consistent results in professional workshop environments.

Advantages

The primary advantage of this drill bit is its HSS-E Co5 material composition, which provides exceptional hardness and thermal stability compared to standard high-speed steel bits. This allows for extended tool life even when working with abrasive or work-hardening materials like stainless steel. The robust design minimizes vibration and deflection, leading to cleaner holes and improved accuracy in every application.

Suitable for

• Drilling stainless steel and high-alloy steels
• General metalworking and fabrication
• Precision drilling in industrial workshops
• Applications requiring high heat resistance

This drill bit may not be suitable for drilling into soft materials like wood or plastic, where the specialized geometry and cobalt content are not required and may lead to suboptimal chip formation. It is also not intended for use in masonry or concrete applications.

Key specifications

• Diameter: 4.8 mm
• Material: HSS-E Co5 (5% Cobalt)
• Standard: DIN 338
• Geometry: NWKa
• Total length: 86 mm
• Working length: 52 mm

How to use

To achieve the best results, secure the workpiece firmly in a vice or clamp to prevent movement. Use a steady, controlled feed rate and appropriate cutting fluid to maintain the temperature of the bit and prolong its service life. Ensure the drill bit is correctly aligned with the center mark before starting the rotation. Apply consistent pressure, allowing the cutting edges to do the work without forcing the tool, which helps prevent overheating and premature wear.

What to consider before purchase

• Verify the compatibility of the 4.8 mm diameter with your specific project requirements.
• Ensure your drilling equipment supports the use of HSS-E cobalt bits for optimal performance.
• Consider the material hardness of your workpiece to ensure this bit is the correct choice.

Usage recommendations: Always wear appropriate eye protection and safety gear when operating drilling equipment. Regularly inspect the drill bit for signs of wear or dulling to maintain precision and safety during operation.
