Graphite HSS Metal Drill Bits, DIN 338, 2 mm, 3 Pieces

The Graphite HSS metal drill bits are precision-engineered tools designed for drilling into various metal surfaces. Manufactured in accordance with the DIN 338 standard, these 2 mm drill bits offer consistent performance and reliability for both professional metalworking and home improvement projects. The high-speed steel construction provides the necessary hardness and heat resistance required for effective material penetration.

Advantages

These drill bits are characterized by their robust high-speed steel composition, which ensures a longer service life and resistance to wear during intensive use. The DIN 338 compliance guarantees that the dimensions and geometry of the bits meet established industrial standards for accuracy and stability. Their design facilitates efficient chip removal, which helps maintain a clean cutting path and prevents overheating during the drilling process.

Suitable for

• Drilling holes in steel and cast iron
• Working with non-ferrous metals such as aluminum or copper
• Precision metalworking tasks
• DIY home repair and maintenance projects

When it may not be suitable

These drill bits are not intended for drilling into masonry, concrete, or hardened stone, as the material composition is specifically optimized for metal. They may also experience premature wear if used on extremely hardened alloys that exceed the standard capabilities of high-speed steel.

Key specifications

• Diameter: 2 mm
• Material: High-speed steel (HSS)
• Standard: DIN 338
• Quantity: 3 pieces per set

How to use

To achieve the best results, secure the workpiece firmly to prevent vibration or movement during drilling. Insert the drill bit into the chuck of your power drill or drill press, ensuring it is centered and tightened securely. Apply steady, moderate pressure while maintaining a consistent speed appropriate for the material being drilled. It is recommended to use a cutting fluid or oil to reduce friction and heat, which will extend the life of the drill bit and improve the quality of the hole.

What to consider before purchase

• Verify that the 2 mm diameter is appropriate for your specific fastener or application requirements.
• Ensure your drill chuck is compatible with standard cylindrical shank drill bits.
• Consider the hardness of the material you intend to drill to ensure it falls within the operational range of HSS tools.

Usage recommendations

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