Centaur Rdf - 123 Series 75 Af Collet 1/2 to 33/64 in

Product Description

The CENTAUR RDF - 123 is a Series 75 AF collet designed for precision toolholding applications in machining environments. It accepts workpiece or tool shank diameters ranging from 1/2 inch (0.5000 inches) up to 33/64 inch (0.5156 inches), giving machinists a tight, accurate grip across that capacity range. The collet measures 1.13 inches in overall diameter and 2.02 inches in overall length. It is installed by machinists and toolroom technicians working with lathes, mills, or dedicated collet chucks that accept the Series 75 AF standard. Proper collet selection is critical to runout control and surface finish quality in close-tolerance work.

This collet is suited for machine shop environments, toolrooms, and production floor applications where consistent clamping force and concentricity are required. The Series 75 AF designation indicates a specific collet body geometry and nose configuration that must match the collet chuck or closer system in use. It is appropriate for both light finishing passes and moderate material-removal operations within its rated capacity range. Technicians should verify that the host machine spindle or chuck accepts Series 75 AF collets before ordering.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Always power down and lock out the machine spindle before inserting or removing a collet. Ensure the collet bore, chuck taper, and closer threads are clean and free of chips or debris before seating the collet. Do not force a collet into a chuck with a size or series mismatch, as this can damage both the collet and the spindle nose.
