Currently, in the process of house construction and decoration, broken bridge aluminum doors and windows are widely used. So, what are the main tools needed during the installation of doors and windows? Here's a brief introduction.  
1. The role of the cutting machine  
The cutting machine is a commonly used tool in door and window installation. It can cut various metal profiles according to the design dimensions and can also cut shapes like triangles and rectangles.  
2. The role of the electric drill  
When installing broken bridge aluminum doors and windows, you will encounter many situations requiring screws to be fastened. This is where the electric drill comes in handy. The drill bit can be replaced with a screwdriver bit, allowing screws to be tightened using the drill's low torque motor.  
3. The role of the impact drill  
When installing doors and windows, it is necessary to drill holes in the walls. Most modern houses use cement walls, and the impact drill, with its high power, is very suitable for drilling into cement walls, making the work highly efficient.  
4. The role of the welding machine  
The main role of the welding machine is to weld iron materials together. During door and window installation, the framework may need to be disassembled and connected according to the house structure. The welding machine can join iron frameworks firmly.  
5. The role of the nail gun  
The main function of the nail gun is to drive steel nails directly into the wall. When securing broken bridge aluminum doors and windows, the nail gun is used to shoot steel nails to fix the window or door frame.  
6. The role of the caulking gun  
The main function of the caulking gun is to squeeze sealant from the tube. After the doors and windows are installed, there may be gaps between the frame and the wall. The caulking gun can be used to fill these gaps, providing a sealing effect.  
The above is a brief introduction to the tools used in door and window construction.
