The basic structure of drills usually includes three parts: handle, neck and working part.The handle is the connection between the drill bit and the drill rod. Its design requires a solid conclusion to ensure that it will not fall off when rotating.The selection of drills has a decisive impact on its performance.Common drills include high -speed steel, tungsten carbide and diamonds.High -speed steel drill bit is widely used in wood and plastic drilling due to its low cost.Tungsten carbide drill bitter has good hardness and abrasion resistance, and is often used in metal and stone processing.For example, the straight handle drill is suitable for drilling of general materials, while the center drill is used to accurately locate the center of the hole.
Although the drill is small, it is an indispensable tool for our lives and work.Whether it is family decoration, large projects, or mechanical manufacturing, it is inseparable from the help of drills to help us.By understanding the type, structure, working principle and application of the drill bit, we can better use this powerful tool to improve our work efficiency and improve our quality of life.
In the structure of the drill, it is mainly composed of three parts: core, drill and drilling handle.Among them, the rhinestone is located at the front of the drill, responsible for cutting into the workpiece and breaking the material; the drilling connecting the drilling core and drilling handle.It is used to connect to the drill, and the rotation of the drill drives the drill rotation.
The basic structure of drills usually includes three parts: handle, neck and working part.The handle is the connection between the drill bit and the drill rod. Its design requires a solid conclusion to ensure that it will not fall off when rotating.The neck is a place with drill bit parameters, such as diameter, material and other information.The work part is responsible for cutting materials, and the design of the drill bit directly affects the effect and efficiency of the drilling.
The selection of drills has a decisive impact on its performance.Common drills include high -speed steel (HSS), tungsn carbide and diamonds.High -speed steel drill bit is widely used in wood and plastic drilling due to its low cost.Tungsten carbide drill bitter has good hardness and abrasion resistance, and is often used in metal and stone processing.As for diamonds, as a super hard material, diamond drills are excellent in drilling in hard materials such as glass and tiles.
There are many types of drill bites. According to their shape and use, they can be divided into straight handle drills, cone drills, central drills, shovel drills.Each drill has its specific application scenarios.For example, the straight handle drill is suitable for drilling of general materials, while the center drill is used to accurately locate the center of the hole.
The application of drills is very extensive. From the home decoration in our daily life to the large -scale construction construction, and to the precise mechanical manufacturing, it is inseparable from the help of the drill.For example, in home decoration, we need to use drills to drill on the wall in order to install various hooks or decorations; in construction construction, we need to use drills to drill on concrete or rocks in order to perform subsequent work; in machinery; in machinery; in machinery; in machinery; in machinery; in machinery; in machinery; in machineryDuring processing, we need to drill on metal or other hard materials with drills for assembly or transformation.
