The Nord Tools 6.0mm twist drill bit is a high-performance cutting tool engineered to meet the DIN 338 standard for precision and reliability. Constructed from high-speed steel alloyed with 5% cobalt (HSSE-Co5), this Type N drill bit is specifically designed to handle the rigorous demands of drilling into tough, high-strength materials. Its robust composition ensures superior heat resistance and structural integrity, making it an essential component for professional metalworking and industrial machining tasks.
Advantages
The primary benefit of this drill bit lies in its cobalt-enriched material, which significantly enhances its hardness and thermal stability compared to standard high-speed steel bits. This allows for consistent performance even when working with materials that generate high friction and heat during the drilling process. The Type N geometry provides an optimal balance between cutting speed and chip removal, ensuring a smooth operation and extended tool life. Its precise 6.0mm diameter makes it highly versatile for creating accurate holes in demanding metal applications.
Suitable for
- Drilling stainless steel
- Machining alloyed steels
- General metalworking tasks
- Professional industrial applications
When it may not be suitable
This drill bit is optimized for metalworking and may experience premature wear if used extensively on abrasive materials like masonry, concrete, or hardened ceramics. It is also not intended for use on soft materials where standard carbon steel bits would be more cost-effective.
Key specifications
- Diameter: 6.0mm
- Material: HSSE-Co5 (High-speed steel with 5% cobalt)
- Standard: DIN 338
- Type: N (Normal helix angle)
How to use
To achieve the best results, ensure the drill bit is securely fastened in a high-quality drill chuck. Start the drilling process at a moderate speed, applying steady and consistent pressure. It is recommended to use a suitable cutting oil or lubricant to reduce friction and dissipate heat, which will significantly prolong the life of the cobalt steel edge. Always ensure the workpiece is firmly clamped to prevent vibration or movement during the drilling operation.
What to consider before purchase
- Verify the required hole diameter for your specific project
- Ensure your drill machine is compatible with the shank size
- Consider the hardness of the material you intend to drill
Usage recommendations
For optimal performance and to prevent the bit from overheating or breaking, always maintain a steady feed rate and use appropriate cooling lubricants when drilling stainless or alloyed steels.
