Thread bit

Threaded drill bit is a widely used drilling tool, widely used in metalworking, construction, machining and other fields. Its main feature is that it has a spiral texture, which can better remove unnecessary chips and improve drilling efficiency and accuracy.

Thread bits are usually made of high-speed steel or carbide, which have good wear resistance and stiffness. Its shape is tapered and divided into cutting area, guide area and holding area. The cutting area is the most frontal part and is responsible for cutting the workpiece. The pilot zone is the part behind the cutting zone that helps the drill to remain stable and accurate. The clamping zone is the part of the drill that attaches to the drill or drill clamp.

The cutting process of the threaded drill bit is completed by rotation and forward motion. During the use, the drill tip must maintain the inherent rotational speed and advancement to ensure the quality and efficiency of the drill. Generally speaking, the harder the material, the lower the rotational speed and the lower the need to use grease to cool and lubricate the cutting surface.

Threading bits have different types of threads, the most common being straight threads, twill threads and spiral threads. Straight grain bits are appropriate for drilling straight holes, twill bits are appropriate for tilting holes, and spiral grain bits are appropriate for threaded holes. Depending on your needs, you can also choose between different thread sizes and hole diameters.

Precautions when using threaded bits include maintaining the sharpness and integrity of the drill bit and preventing wear and excessive damage. During use, care should be taken to clean up unnecessary chips in a timely manner to avoid clogging the cutting area. In addition, for hard materials, you can pre-drill holes in the workpiece or use the center drill bit to position and prevent the drill bit from slipping and deflecting.

In short, threading bit is a very important drilling tool with the advantages of safety, accuracy and convenience. Through reasonable selection and use, it can meet the processing needs of various workpieces, and improve the efficiency and quality of production. At the same time, proper service and maintenance can also extend the life of the drill bit and save costs.
