How to use

To use these drill bits, insert the shank into the chuck of your drill and tighten it securely. Ensure the workpiece is properly clamped or held in a vice to prevent movement during the drilling process. Start the drill at a moderate speed and apply steady, controlled pressure. It is recommended to use a cutting fluid when drilling into metal to reduce friction and heat, which extends the life of the bit.

What to consider before purchase

• Verify that your drill chuck is compatible with a 3.5mm straight shank bit.
• Ensure the material you intend to drill is suitable for high-speed steel tools.
• Consider purchasing a depth stop if you require consistent hole depths.

Usage recommendations

Always wear appropriate eye protection when drilling. Periodically clear metal chips from the hole to prevent clogging and overheating. If the bit becomes hot to the touch, allow it to cool before continuing.
