1. When drilling steel parts, please ensure sufficient cooling and use metal cutting fluid. 2. Good drill pipe rigidity and guide rail clearance can improve the drilling accuracy and the life of the drill bit 3. Please ensure that the space between the magnetic base and the workpiece is flat and clean. 4. When drilling thin plates, the workpiece should be reinforced. When drilling large workpieces, please ensure that the workpiece is stable. 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., it is not necessary to use coolant, but to use compressed air to help chip removal. 7. Please remove the iron filings wrapped around the drill body in time to ensure smooth chip removal.
