Accupro 584471 Tg/pg 100 Collet 0.8125 in Bore

Product Description

The ACCUPRO 584471 is a standard single-angle collet designed for TG/PG 100 toolholding systems used in precision machining applications. Built to accept a 0.8125-inch (13/16 inch) bore, this collet features a maximum body diameter of 1.278 inches and an overall length of 2.386 inches. It delivers a total indicator runout (TIR) of 0.00078 inches (0.0200 mm), making it suitable for applications where concentricity and repeatability are critical. Machinists and tool crib personnel working with TG/PG 100 collet chucks will find this a direct-fit replacement or supplemental tooling addition.

The 584471 is intended for use in TG/PG 100 collet chuck systems commonly found on CNC machining centers, manual mills, and similar spindle-driven equipment. The single-angle collet design provides consistent gripping force across the full bore length, which supports accurate stock work, drilling, reaming, and light milling operations. This collet is sold individually and is appropriate for production and maintenance environments where toolholding precision directly affects part quality.

Compatibility

Designed for use with TG/PG 100 series collet chuck systems. Compatible with any toolholder or chuck body manufactured to accept TG/PG 100 standard single-angle collets with a 0.8125-inch bore capacity.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with collet chuck systems. Before inserting or removing the collet, ensure the spindle is fully stopped and the machine is in a safe, powered-down state. Use the appropriate collet nut and torque wrench rated for TG/PG 100 systems; do not use makeshift tooling to seat or remove the collet. Inspect the collet bore, body taper, and mating chuck surfaces for debris or wear before assembly to maintain rated TIR performance.
