The CENTAUR RDF - 057 is a Series 50 AF collet designed to hold workpieces or tooling within a clamping range of 9/64 inch to 5/32 inch (0.1563 inches at maximum capacity). The collet measures 0.72 inches in overall diameter and 1.16 inches in overall length, making it a compact, precision workholding component. It is installed in compatible collet chucks or collet holders on lathes, mills, and similar machine tools. Machinists and toolroom technicians working with small-diameter stock or tooling in production and maintenance environments will find this collet well-suited to close-tolerance workholding tasks.
The RDF - 057 fits into Series 50 AF collet systems and is appropriate for light machining, grinding, and secondary operations where small shank or stock diameters in the 9/64 to 5/32 inch range are common. It suits both production shop environments and toolroom setups where consistent, repeatable gripping of small-diameter cylindrical workpieces is required. No specific compatible machine models were listed in the product data; verify Series 50 AF chuck compatibility before ordering.
Designed for use with Series 50 AF collet chucks and holders that accept this collet series. Verify chuck and spindle compatibility with Series 50 AF specifications before installation. No specific machine model compatibility was provided in the product data.
Installation is performed by qualified machinists or toolroom technicians familiar with collet chuck systems. Always power down and lock out the machine spindle before inserting or removing a collet. Ensure the collet bore and chuck taper are clean and free of chips or debris before seating. Do not force the collet into the chuck; proper seating relies on a clean, undamaged taper interface.
