How to use
To achieve the best results, secure your workpiece firmly to prevent vibration or movement during the drilling process. Use a center punch to mark the exact location of the hole to ensure the drill bit does not wander upon starting. Apply steady, moderate pressure and use a suitable cutting oil to lubricate the bit, which will help reduce friction and extend the life of the tool. Maintain a consistent drill speed appropriate for the material being processed.
What to consider before purchase
Ensure the 4mm diameter matches your specific project requirements
Check the compatibility of your drill chuck with the cylindrical shank
Consider purchasing a set if you require multiple sizes for your project
Usage recommendations
Always wear appropriate eye protection when drilling metal to prevent injury from flying chips. Regularly inspect the drill bit for signs of wear or dullness and replace it when necessary to maintain drilling efficiency and safety.
