The Nord Tools DIN 338 HSS-R 3.0 mm Type N twist drill bit is a precision-engineered tool designed for reliable performance when drilling into various metallic materials. Manufactured from high-speed steel using a rolling process, this drill bit offers a balance of strength and flexibility, making it a dependable choice for both professional workshops and home improvement projects.
Advantages
This drill bit features a standard N-type geometry, which is optimized for drilling in materials with normal tensile strength. The HSS-R construction provides excellent heat resistance and durability, ensuring a longer service life even during repeated use. Its design facilitates efficient chip removal, which helps to prevent clogging and overheating during the drilling process, resulting in cleaner holes and improved accuracy.
Suitable for
- Drilling into mild steel and carbon steel
- Working with cast iron and non-ferrous metals
- General metalworking tasks
- DIY home repair and maintenance projects
When it may not be suitable
This drill bit is not intended for drilling into hardened or high-alloy steels, as the material hardness may cause premature wear or damage to the cutting edge. It is also not recommended for masonry, concrete, or ceramic materials, which require specialized drill bits with different tip geometries and material compositions.
Key specifications
- Diameter: 3.0 mm
- Material: HSS-R (Rolled High-Speed Steel)
- Standard: DIN 338
- Type: N (Normal helix angle)
- Application: Metal drilling
How to use
To achieve the best results, ensure the drill bit is securely fastened in the chuck of your power drill or drill press. Mark the center point of the hole to be drilled to prevent the bit from wandering. Apply steady, moderate pressure while maintaining a consistent speed appropriate for the material being drilled. It is advisable to use a cutting oil or lubricant when working with metal to reduce friction, dissipate heat, and extend the life of the drill bit.
What to consider before purchase
- Verify the required diameter for your specific application
- Ensure your drill chuck is compatible with a 3.0 mm shank
- Consider purchasing a set if you require multiple sizes
Usage recommendations
Always wear appropriate eye protection and safety gear when operating drilling equipment. Regularly inspect the drill bit for signs of wear or dullness and replace it when necessary to maintain drilling efficiency and safety.
