5C hex collets are designed for direct clamping of hexagonal bars and components, eliminating the need for adapters and ensuring precise geometric engagement between the collet and the workpiece. The system operates through controlled elastic deformation, with the collet being pulled into a tapered spindle seat by a drawbar, generating uniform clamping across the profile surfaces. This configuration allows efficient torque transmission, preventing slippage and ensuring high torsional stability during machining.

In practical applications, 5C hex collets are particularly suited for CNC and automatic lathes where maintaining angular positioning is essential. Direct contact with the profile surfaces reduces centering errors and improves clamping quality compared to universal solutions. They are widely used in mass production environments requiring consistent accuracy over time.

Selection criteria are based on the hex profile size and compatibility with the drawbar system. Compared to round collets, hex versions offer significant advantages in torque transmission, making them ideal for operations involving rotational stress.

Technically, 5C hex collets provide a specialized solution for non-cylindrical workholding, balancing precision, stability, and operational reliability.
