Special tools are special tools that are manufactured according to individual customer requirements. They are mainly used when a production task can no longer be handled with standard tools. This is the case, for example, when the machining task is too complex for standard tools or when lower cycle times are required. In practice, several tools must then be used, which results in longer downtimes, more wear and a higher susceptibility to errors.
A special tool is an alternative in this case. These are tools that are specially manufactured for individual requirements. This can be a mixture of different tools, for example, with which several operations can be carried out without downtime. However, there are also special tools for individual work steps whose geometries are provided with special extras. Special tools made of different materials such as carbide can also be manufactured entirely according to the customer's requirements.
Due to their practically limitless variety of shapes, special milling cutters are mainly used where complex milling and drilling processes and high cutting speeds are involved. A frequent application, for example, is the step drill. Here, a special tool offers great time savings because all steps can be produced in a single operation and because they have a very long service life with high-performance materials. Another area of application is, for example, reaming and forming tools, with which certain geometries and shapes can be produced in a single operation.
