How to use
To achieve the best results, secure your workpiece firmly to prevent vibration or movement during the drilling process. Insert the drill bit into the chuck of your power tool and tighten it securely. It is recommended to use a center punch to mark the exact drilling location to prevent the bit from wandering. Apply steady, moderate pressure and use a lower rotational speed for metal to prevent overheating. Periodically clear the chips from the hole and use a suitable cutting oil to lubricate the bit, which helps maintain temperature and improves the quality of the finish.
What to consider before purchase
Verify that your drill chuck is compatible with a standard cylindrical shank.
Ensure the 4mm diameter meets the specific requirements of your project.
Check if your power tool supports the recommended speed settings for metal drilling.
Usage recommendations
For optimal performance and longevity, always use a cooling lubricant when drilling into metal and avoid applying excessive force, which can cause the bit to break or overheat.
