Tap drills are suitable for drilling holes in a variety of metal materials such as steel, aluminium alloys, copper alloys and stainless steel. They can also be used to drill holes in non-metallic materials such as plastics, fibreglass and wood. Tap drills are designed with a structure that allows them to drill efficiently in hard materials while maintaining good cut quality and hole accuracy.

Tap drills are usually made of tungsten carbide, whose excellent hardness and wear resistance ensure stability and longevity during the drilling process. In addition, the sharp cutting edge design and special helical structure of tap drills can effectively transfer the cutting force to the workpiece, improving drilling efficiency and quality.

In addition to general metallic and non-metallic materials, tap drills can also be used for the machining of some special workpieces, such as automotive parts, aerospace components, moulds and dies. In these areas, tap drills usually need to be combined with special cooling and lubrication methods or machining processes to ensure that the drilling process does not generate excessive heat or damage the surface of the workpiece.

In short, tap drills are versatile drilling tools that are suitable for punching holes in a variety of metallic and non-metallic materials. They offer efficient, stable and accurate drilling performance and are widely used in manufacturing, aerospace, automotive, moulds and other fields. By choosing the right tap drill specifications and process parameters, efficient drilling processing can be achieved, improving productivity and product quality.
