1. When drilling steel, please ensure sufficient cooling and use metal cutting fluid.
2. Good drill pipe rigidity and guide rail clearance can improve drilling accuracy and bit life
3. Please ensure the leveling and cleaning between the magnetic base and the workpiece.
4. When drilling a thin plate, it is necessary to reinforce the workpiece and ensure the stability of the workpiece when drilling large workpieces.
5. At the beginning and end of the drilling, the feed should be reduced by 1/3.
6. For materials with a lot of fine powder during drilling, such as cast iron, cast copper, etc., you can use compressed air to help remove chips without using coolant.
7. Please remove the iron filings on the drill body in time to ensure smooth chip removal.
