Centaur Rdf - 127 Series 75 Af Collet 9/16 to 37/64 in

Product Description

The CENTAUR RDF - 127 is a Series 75 AF collet designed for precision workholding in machining operations. It accepts stock ranging from 9/16 inch (minimum) to 37/64 inch (0.5781 inch maximum) in capacity, making it suited for close-tolerance work near the upper end of that range. The collet measures 1.13 inches in overall diameter and 2.02 inches in overall length. Machinists and toolroom technicians install this collet in compatible Series 75 AF collet chucks or collet closers on lathes, screw machines, and similar turning equipment where consistent grip and runout control are required.

This collet is used in production and job-shop machining environments where workholding accuracy directly affects part quality. It is appropriate for both light finishing passes and standard turning operations on bar stock or round workpieces within its stated capacity range. The Series 75 AF designation identifies the collet system, which must match the chuck or closer in use. Typical applications include CNC lathes, manual engine lathes, and automatic screw machines equipped with Series 75 AF-compatible spindles.

Key Features

• Collet capacity range: 9/16 inch to 37/64 inch (0.5781 inch maximum)

• Series 75 AF designation ensures system-matched clamping geometry
• Single-piece packaging with a minimum order quantity of one unit

Compatibility

Designed for use with Series 75 AF collet chucks and collet closers that accept 1.13-inch diameter collets. Verify that the spindle or closer in use is rated for the Series 75 AF collet system before installation.

Installation Notes

Installation of collets should be performed by a qualified machinist with the machine powered down and the spindle fully stopped. Ensure the collet bore, collet closer, and chuck threads are clean and free of chips or debris before seating the collet. Do not exceed the collet's stated maximum capacity, as overloading can cause workpiece slippage or collet damage. Refer to the machine manufacturer's documentation for correct closer draw-bar torque and collet seating procedures.
