The CENTAUR RDF - 164 is a Series 100 AF collet designed for precision tool holding in machining and metalworking applications. It accepts tool or workpiece diameters from 0.25 inches (1/4 inch) up to 0.2656 inches (17/64 inch), providing a tight, accurate grip across that range. With an overall diameter of 1.45 inches and an overall length of 2.5 inches, this collet fits standard Series 100 AF collet chucks and closers. Machinists, toolroom technicians, and CNC operators install this type of collet when securing small-diameter stock, end mills, or round-shank tooling that falls within its rated capacity range.
This collet is suited to production machining environments where repeatable tool runout and secure clamping are required. It is typically used in lathes, milling machines, and machining centers equipped with Series 100 AF spindle noses or collet chucks. Applications include turning, milling, drilling, and grinding operations on small-diameter workpieces or cutting tools that fall within the 0.25 to 0.2656 inch capacity range. A single collet is supplied per package.
Designed as a direct-fit replacement or addition for Series 100 AF collet chucks and closers that accept the standard 1.45 inch diameter collet body form.
Collet installation and removal should be performed by a qualified machinist with the spindle fully stopped and the machine locked out per standard OSHA lockout/tagout procedures. Inspect the collet bore and chuck taper for chips or burrs before seating the collet, as contamination will affect runout and clamping force. Do not exceed the rated capacity range — forcing an oversized workpiece or tool shank can permanently deform the collet fingers. Torque the closer nut or drawbar according to the machine tool manufacturer specifications for the Series 100 AF system.
