The Nord Tools DIN 338 HSS-R twist drill bit with an 11.5 mm diameter is a professional-grade cutting tool engineered for reliable performance in metalworking applications. Manufactured according to the DIN 338 standard, this Type N drill bit is crafted from high-speed steel, ensuring excellent durability and heat resistance during intensive drilling tasks. Its robust geometry allows for consistent chip removal and precise hole formation in various metallic materials.
Advantages
This drill bit offers significant benefits for both professional workshops and industrial environments. The high-speed steel construction provides a balance of hardness and toughness, which helps maintain the cutting edge over extended periods of use. The Type N design is optimized for standard drilling conditions, ensuring stability and accuracy when working with steel, cast iron, and non-ferrous metals. Its precise manufacturing ensures that the 11.5 mm diameter remains consistent, facilitating clean and accurate holes for fasteners or other mechanical components.
Suitable for
- Drilling in structural steel and carbon steel
- Working with cast iron components
- Machining non-ferrous metals such as aluminum or copper
- General workshop maintenance and repair tasks
When it may not be suitable
This drill bit is not intended for drilling into hardened steel, stainless steel alloys, or masonry, as these materials require specialized cobalt or carbide-tipped bits to prevent premature wear or breakage. It is also not suitable for use in impact drilling modes on hammer drills.
Key specifications
- Diameter: 11.5 mm
- Material: High-speed steel (HSS-R)
- Standard: DIN 338
- Type: N (normal helix angle)
- Application: Metal drilling
How to use
To achieve the best results, secure the workpiece firmly in a vice or clamp to prevent movement during the drilling process. Insert the drill bit into the chuck of your power drill or drill press, ensuring it is tightened securely. Start the drilling process at a moderate speed, applying steady and controlled pressure. It is recommended to use a suitable cutting oil or coolant to reduce friction and heat, which will significantly extend the lifespan of the drill bit and improve the quality of the hole.
What to consider before purchase
- Ensure your drill chuck is compatible with an 11.5 mm shank diameter.
- Verify that the material you intend to drill is compatible with HSS-R steel.
- Consider using a center punch to mark the drilling location for higher precision.
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 if necessary to maintain drilling efficiency and safety.
