1. When drilling steel parts, please ensure sufficient cooling and use metal cutting fluid.
2. Good drill rod rigidity and guide rail clearance can improve drilling accuracy and drill bit life.
3. Please ensure the flatness and cleanliness between the magnetic seat and the workpiece.
4. When drilling thin plates, the workpiece should be reinforced, and when drilling large workpieces, please ensure the stability of the workpiece.
5. At the beginning and end of drilling, the feed rate should be reduced by 1/3.
6. For materials with a large amount of fine powder during drilling, such as cast iron, cast copper, etc., compressed air can be used to assist in chip removal without using coolant.
7. Please promptly remove the iron shavings wrapped around the drill body to ensure smooth chip removal.
