The Nord Tools DIN 338 HSS-R 4.8 mm twist drill bit is a professional-grade tool engineered for precision drilling in various metal materials. Manufactured according to the DIN 338 standard, this Type N drill bit features a robust high-speed steel construction with a rolled finish, ensuring consistent performance and structural integrity during demanding drilling operations. Its design is optimized for standard workshop environments where reliability and accuracy are essential for achieving clean, precise holes.
Advantages
This drill bit offers exceptional durability due to its high-speed steel composition, which maintains its cutting edge even under moderate heat and friction. The rolled manufacturing process enhances the toughness of the tool, making it resistant to breakage during standard drilling tasks. Its geometry is specifically designed to facilitate efficient chip removal, which prevents clogging and ensures a smooth drilling process in both industrial and home workshop settings.
Suitable for
- Drilling into unalloyed and alloyed steel
- Working with grey cast iron
- Processing non-ferrous metals such as aluminum or copper
- General metalworking and DIY repair projects
When it may not be suitable
This drill bit is not recommended for drilling into hardened steel, stainless steel, or highly abrasive materials, as these require specialized cobalt-alloyed bits to prevent premature wear. It is also not intended for use in masonry, concrete, or ceramic tiles.
Key specifications
- Diameter: 4.8 mm
- Material: High-speed steel (HSS)
- Standard: DIN 338
- Type: N (Normal helix angle)
- Finish: Rolled
How to use
To achieve the best results, secure your workpiece firmly in a vice or clamp to prevent vibration. Insert the drill bit into the chuck of your power drill or drill press, ensuring it is tightened securely. Align the tip of the drill bit with your marked center point and apply steady, moderate pressure while maintaining a consistent drilling speed. It is advisable to use a cutting oil or lubricant when drilling into metal to reduce heat buildup and extend the lifespan of the bit.
What to consider before purchase
- Verify that your drill chuck is compatible with a 4.8 mm shank diameter.
- Ensure the material you intend to drill is within the recommended hardness range for HSS-R bits.
- Consider purchasing a set of bits if you require multiple sizes for your project.
Usage recommendations
Always wear appropriate eye protection and safety gear when operating drilling equipment. Periodically inspect the drill bit for signs of dulling or damage to ensure continued precision and safety during operation.
