Tool holders are the interface to the machine spindle and are also the interface to the tools. In brief, Tool holders (toolholders) are the physical interface between tooling and the machine tool. They come in a multiple of different machine mount styles from the older R8 style to newer HSK or VDI mount. Tool holders have three main parts: the taper, the flange, and the collet pocket.
Tool holder is a machining component that have been designed to introduce additional properties to the cutting action, it provides a better grip and precision operation. Tool holder have a shank at one end by which it is clamped to a machine and at the other end to hold small interchangeable cutting bits. Tool holders vary based on the method used to hold the end mill in place. Here is a basic overview of the CNC milling tool holder types we offer:
Shrink fit holders: This type of holder uses heating and cooling to apply clamping force to the cutting tool. Shrink fit holders offer powerful grip and can dramatically extend tool life.
Collet chucks: A collet chuck grips the end mill with a slotted collar. Standard collets are sized by millimeter, and they can be customized as well.
End mill holders: These parts use a set screw to secure the cutting tool. They have small nose diameters and are available in a variety of lengths.
Tap holders: This category includes rigid, floating, and cartridge-style tap holders. Adapters are also available so you can use more tools on the same holder.
Tool holders are the interface to the machine spindle and are also the interface to the tools. Metalextra offers a variety of shanks common to the market, including DV, BT or CAT steep tapers, which are also available in BIG-PLUS. HSK hollow shank tapers and BIG CAPTO shanks are available too.
Tools are clamped in a positive or non-positive manner and Metalextra has a large variety of different designs. Depending on the application, tool holders are particularly suitable for drilling, milling or reaming. Furthermore, a tool holder can simply be an interface to a complete tool combination.
