The CENTAUR RDF - 079 is a Series 50 AF collet designed for precision tool holding in milling, drilling, and machining operations. It accepts workpiece or tool shank diameters from 7/16 inch (0.4375 inches) up to 29/64 inch (0.4531 inches), making it suitable for close-tolerance tooling applications. The collet measures 0.72 inches in overall diameter and 1.16 inches in overall length. Machinists and toolroom technicians install this collet into compatible Series 50 AF collet chucks to secure cutting tools, drills, or round-shank workholding fixtures during machining. It ships individually and is available in single-unit quantities.
The RDF - 079 fits applications where a Series 50 AF collet chuck is the specified workholding method. This includes CNC machining centers, manual mills, and toolroom equipment set up for the Series 50 AF collet system. The narrow capacity range between 7/16 inch and 29/64 inch is suited for applications requiring a dedicated collet for a specific tool shank diameter rather than a wide-range chuck. Industrial maintenance shops and production machine shops are the typical end users for this collet size.
Designed for use with Series 50 AF collet chucks that accept this standard collet form factor. Consult your chuck manufacturer specifications to confirm Series 50 AF collet fitment before installation.
Installation should be performed by a qualified machinist or toolroom technician familiar with collet chuck systems. Power down and lock out the machine spindle before inserting or removing the collet. Inspect the collet bore and chuck taper for chips, burrs, or wear before seating the collet. Do not exceed the stated capacity range, as oversize tool shanks can damage the collet or compromise tool retention.
