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 drilling speed suitable for the specific type of metal being worked. It is recommended to use a cutting oil or lubricant to reduce friction and heat, which will help preserve the sharpness of the drill bit and improve the overall finish of the hole.

What to consider before purchase

• Ensure the drill bit diameter matches your specific project requirements
• Check that your drill chuck is compatible with a 7.0 mm shank size
• Verify the material hardness of your workpiece to ensure it falls within the recommended range for this tool

Usage recommendations

Always wear appropriate eye protection and safety gear when operating power tools. Periodically inspect the drill bit for signs of wear or dullness to maintain optimal drilling performance and safety.
