General metalworking and DIY repair tasks
When it may not be suitable
These drill bits are specifically optimized for metal materials and may experience premature wear or poor performance if used on masonry, concrete, or extremely hard ceramic tiles. They are also not intended for use with wood or plastics where specialized geometry is required for optimal chip evacuation.
Key specifications
Diameter: 5.5 mm
Material: High-speed steel (HSS)
Standard: DIN 338
Quantity: 2 pieces per pack
How to use
To achieve the best results, secure your workpiece firmly in a vice or clamp to prevent movement during the drilling process. Start by marking the center point of the hole to ensure accuracy. Apply steady, moderate pressure while maintaining a consistent rotational speed suitable for the material being drilled. It is recommended to use a cutting oil or lubricant to reduce friction and heat, which will significantly improve the finish of the hole and prolong the life of the drill bit.
What to consider before purchase
Verify that your drill chuck is compatible with a 5.5 mm cylindrical shank.
Ensure the drill bit diameter matches your specific fastener or project requirements.
Check the maximum rotational speed of your power tool to avoid overheating the bit.
Usage recommendations
Always wear appropriate eye protection and safety gear when operating power tools. Periodically inspect the drill bit for signs of dulling or damage and replace it if necessary to maintain drilling efficiency and safety.
