• General metalworking and fabrication
• DIY repair and maintenance tasks

When it may not be suitable

This drill bit is not intended for drilling into hardened steel, stainless steel, or high-alloy materials, as these require specialized cobalt or carbide tooling. It is also not suitable for masonry, concrete, or wood applications where different flute geometries are required for optimal performance.

Key specifications

• Diameter: 2.5 mm
• Material: High-speed steel (HSS-R)
• Standard: DIN 338
• Type: N (Normal helix)
• 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 of the hole to be drilled and use a center punch to create a small indentation, which helps prevent the bit from wandering during the initial contact. Apply steady, moderate pressure while maintaining a consistent drilling speed suitable for the material. It is recommended to use a cutting oil or lubricant to reduce friction and heat, which will extend the lifespan of the drill bit and improve the quality of the hole.

What to consider before purchase

• Verify the required diameter for your specific project needs.
• Ensure your drill chuck is compatible with a 2.5 mm shank.
• Check the material compatibility to ensure it matches your workpiece.

Usage recommendations

Always wear appropriate eye protection when drilling metal. Periodically inspect the drill bit for signs of dulling or damage and replace it if necessary to maintain precision and safety.
