Twist drills typically range in diameter from 0.25 to 80 mm. It mainly consists of a working part and a handle. It is the most widely used hole machining tool.
So how should we maintain the twist drill?
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 drilling accuracy and drill life.
3. Please ensure that the magnetic base and the workpiece are flat and clean.
4. When drilling thin plates, the workpiece should be reinforced. 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 number of fine powders during drilling, such as cast iron, cast copper, etc., you can use compressed air to help chip removal without using coolant.
7. Please remove the iron chips wrapped around the drill body in time to ensure smooth chip removal.
