Centaur Rdf - 137 Series 75 Af Collet 23/32 to 47/64 in

Product Description

The CENTAUR RDF - 137 is a Series 75 AF collet designed to hold workpieces ranging from 23/32 inches to 47/64 inches (0.7344 inches maximum capacity) in diameter. With an overall diameter of 1.13 inches and an overall length of 2.02 inches, this collet is built for precision workholding in machining applications. It is installed by machinists and toolroom professionals who require consistent, repeatable clamping force across the specified capacity range. The compact form factor and Series 75 AF designation make it a straightforward drop-in for compatible collet chucks and collet blocks in that series.

This collet is suited for use in milling, turning, and grinding setups where a Series 75 AF collet chuck is already in service. It handles stock and workpieces at the upper range of the 23/32- to 47/64-inch diameter window, making it useful for intermediate-diameter round stock, hex stock, or square stock depending on the collet configuration. Typical installation environments include manual mills, CNC machining centers, and bench lathes in job shop and production settings.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Always power down and lock out the machine before inserting or removing a collet. Ensure the collet, chuck bore, and clamping nut are clean and free of chips or debris before seating the collet. Do not force the collet into the chuck; proper seating should require only hand pressure followed by torquing the clamping nut per the chuck manufacturer specifications.
