　　Maintenance of drill bits
　　
　　1. When drilling steel parts, please ensure sufficient cooling and use metal cutting fluid.
　　
　　2. Good drill pipe rigidity and rail clearance can improve the accuracy of drilling and the life of the drill.
　　
　　3. Please ensure that the magnetic base and the workpiece are level and clean.
　　
　　4. When drilling thin plates, reinforce the workpiece, 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., no coolant can be used, and 7. compressed air is used to help chip removal.
　　
　　8. Please remove the iron filings wound on the drill body in time to ensure smooth chip removal.
