Nord Tools DIN 338 HSS-CO5 Type N Twist Drill Bit 2.8 mm

The Nord Tools DIN 338 HSS-CO5 Type N twist drill bit with a 2.8 mm diameter is a professional-grade cutting tool engineered for high-precision drilling tasks in metal. Constructed from high-speed steel alloyed with 5% cobalt, this drill bit provides superior thermal stability and structural integrity, making it an ideal choice for demanding industrial environments and professional workshops where reliability is paramount.

Advantages

The primary benefit of this drill bit lies in its cobalt-enriched composition, which significantly increases its resistance to heat generated during high-speed drilling operations. This material property ensures that the cutting edge remains sharp for extended periods, reducing the frequency of tool changes and improving overall workflow efficiency. The Type N geometry is specifically optimized for standard drilling conditions, providing excellent chip removal and consistent hole accuracy in both alloyed and unalloyed steel materials.

Suitable for

• Drilling into alloyed and unalloyed steel
• Precision metalworking in industrial settings
• General workshop maintenance and repair tasks
• Creating accurate pilot holes for fasteners

When it may not be suitable

This drill bit is specifically optimized for metalworking and may not perform efficiently when used on soft materials like wood or plastic, where specialized geometry is preferred. It is also not recommended for use on hardened or extremely abrasive materials that require specialized carbide-tipped tooling.

Key specifications

• Diameter: 2.8 mm
• Material: HSS-CO5 (High-Speed Steel with 5% Cobalt)
• Standard: DIN 338
• Type: N (Normal helix angle)

How to use

To achieve optimal results, ensure the drill bit is securely fastened in a compatible drill chuck. Begin by marking the center point of the hole to prevent the bit from wandering. Apply steady, moderate pressure while maintaining a consistent rotational speed appropriate for the material being drilled. Using a suitable cutting fluid or lubricant is highly recommended to dissipate heat and extend the lifespan of the tool.

What to consider before purchase

• Verify the compatibility of the 2.8 mm shank size with your existing drill chuck
• Ensure the material being drilled is within the hardness range suitable for HSS-CO5 steel
• Consider purchasing multiple units if performing high-volume drilling tasks

Usage recommendations

Always wear appropriate eye protection when drilling metal. Ensure the workpiece is firmly clamped to prevent movement during the operation, and allow the drill bit to cool down periodically if working on thick metal sections to maintain its structural properties.
