How to remove the ROTARY HAMMER

1. First, we need to rotate the chuck to the maximum range, prepare a screwdriver, and remove the screws inside. Carefully observe that the internal screws are reversed, so we need to follow the clockwise direction to be able to loosen them.

2. Next, take out the screw, use a small screwdriver to clamp on the heat sink, and follow the counterclockwise direction to take out the chuck directly. If there is a problem of unscrewing, you can hit the outside with a ROTARY HAMMER, and then use a screwdriver to follow the counterclockwise direction. It will be easier to remove it, and then install a new chuck.

Second, what are the classifications of electric drills

Electric drill can achieve the purpose of drilling mainly through power. It is the most common tool for electric tools, and the demand is relatively large. According to the specifications of the electric drill, there are large or small, for example, some are 4 mm or 13 mm, 16 mm, the largest is 49 mm and so on. The larger the number, the greater the corresponding tensile strength and the larger the size of the hole.

For percussion drills, there is a button on the chuck of the drill bit, which can be used for rotation adjustment. Its impact force is slightly larger than that of a hand electric drill. It can drill reinforced concrete, but the effect is not particularly good.

If you want a better effect, you can choose an electric hammer. Its impact capacity will be stronger. It can drill reinforced concrete and produce a great impact. The strength can split the stone and divide the gold.
