The CENTAUR RDF - 107 is a Series 75 AF collet designed to hold workpieces ranging from 17/64 inch (minimum) to 9/32 inch (0.2813 inches, maximum) in capacity. With an overall diameter of 1.13 inches and an overall length of 2.02 inches, this collet provides a compact, precise clamping solution for use in compatible collet chucks and toolholding systems. It is intended for machinists, toolroom technicians, and production shop personnel who require accurate, repeatable workholding on turning centers, milling machines, or screw machines.
This collet is suited for light to medium-duty machining applications where close-tolerance workholding is required. Its capacity range makes it appropriate for gripping smaller-diameter round stock, bar stock, or tooling shanks. It fits into Series 75 AF collet chuck systems and is a standard replacement or additional collet for shops maintaining a full capacity range in that series. Typical users include CNC machinists and manual lathe operators working with small-diameter workpieces in production or job-shop environments.
Designed for use with Series 75 AF collet chuck systems. Consult your toolholding system documentation to confirm collet series compatibility before installation.
Installation should be performed by a qualified machinist familiar with collet chuck systems. Before installing or removing a collet, ensure the machine spindle is fully stopped and the machine is powered down or placed in a safe locked-out state per your facility lockout/tagout procedures. Inspect the collet bore and chuck taper for debris or damage before seating the collet. Do not exceed the stated capacity range, as overloading a collet can cause workpiece slippage or collet damage.
