Maintenance of drill bits

⒈ When drilling steel parts, please ensure sufficient cooling and use metal cutting fluid.

⒉Good drill pipe rigidity and guide rail clearance can improve drilling accuracy and drill life

⒊ Please ensure the level and cleanliness between the magnetic base and the workpiece.

⒋When drilling thin plates, the workpiece should be reinforced. When drilling large workpieces, please ensure the stability of the workpiece.

⒌At the beginning and end of drilling, the feed rate should be reduced by 1/3.

⒍ For materials with a large amount of fine powder during drilling, such as cast iron, cast copper, etc., you can use compressed air to help chip removal without using coolant.

⒎ Please remove the iron filings wrapped around the drill body in time to ensure chip removal
