The polygonal clamping system is one of those highly engineered devices that is surprisingly simple: a ground polygon-shaped bore rigidly clamps a cutting tool in three places.
For high-speed applications, polygonal clamping is a great solution since the clamping of the tool shank is done by the elastic deformation of the holder. The main advantage of these toolholders is its extremely slim design.

There are two versions available on the market to cover different applications. A slim version of the toolholder, which stands out with its extremely slim design of the tool shank and its long reach of the tool. It is even possible to use shorter cutting tools with this holder, which in return, results in lower costs for the user. The rigid version of the toolholder has a bigger, and therefore, stiffer body of the holder and offers better qualities with regard to radial force compensation. Both versions can be used with long extensions, which make them even more flexible for difficult machining tasks.

Clamping of the tool or an extension is done within the elastic range of the material of the tool shank. Therefore, there are no restrictions with regard to the lifetime of the tool. Changing a tool can be done within seconds by using an external clamping device. This device does not need any external power source and therefore can be used anywhere. This fact makes polygonal clamping systems very interesting for applications that require a frequent tool change.
