Metal cutting tool sets such as burins, hand saws, taps, and wrenches play an important role in metal cutting and care is required when using them. The following is a detailed description of the precautions for the tool sets.
Jack and the chain hoist are the two tools inside the tool set. Because the jack has the tool to lift heavy objects without auxiliary equipment, and the jacking is slow, uniform, stable, and suitable for sample equipment installation deviation and object variation, so it is widely used in installation and construction. A chain hoist (also known as an inverted chain) is a small lifting tool that does not require bottom padding to be fixed and can lift heavy objects in space in any kind of the desired position. The following is a detailed description of the two tools of note.
