CBA collets for reaming and rigid tapping with ER16 seat according to DIN 6499 B are designed for high-precision machining applications where dimensional stability and zero transmission play are essential. These collets represent an advanced technical solution for synchronized operations, where thread quality and bore geometry are critical to the final workpiece performance.

Their operating principle is based on a rigid clamping system that completely eliminates elastic compensation typical of floating holders. This ensures perfect synchronization between machine feed and tool rotation, preventing pitch errors during tapping and guaranteeing consistent, repeatable thread quality. In reaming operations, the rigidity of the system enables tight tolerances, reducing ovality and improving surface finish.

CBA collets with ER16 interface cover a bore range from 2 to 7 mm, making them highly versatile for precision machining of small to medium components. Their compact dimensions (D=17 mm, L=29 mm) allow optimal integration even in limited spindle spaces while maintaining high structural rigidity.

From an application standpoint, these collets are widely used in automotive manufacturing, precision mechanical production, subcontract machining, and machine tool building. They are particularly suitable for production cycles where repeatability and scrap reduction are critical.

Another key advantage is the reduction of geometrical and form errors such as runout and misalignment, contributing to improved quality control and process stability. The absence of internal play ensures direct torque transmission, reducing tool wear and increasing machining efficiency.

Selecting the correct CBA ER16 collet requires evaluating the bore diameter, machine-tool rigidity, and operating conditions, especially in rigid tapping cycles where synchronization is crucial. This is a highly specialized solution designed for technicians and engineers requiring maximum performance and long-term reliability.
