Accupro 784554 Tg/pg 75 Single Angle Collet 0.5 Inch

Product Description

The ACCUPRO 784554 is a standard single angle collet in the TG/PG 75 series, designed for use in TG/PG 75 toolholding systems on milling machines and machining centers. It accepts a 0.5 inch (1/2 inch) shank diameter and delivers a total indicator reading (TIR) of 0.00078 inches (0.02 mm), providing the close runout tolerance that precision machining applications require. The maximum body diameter measures 1.063 inches and the overall length is 1.844 inches. This collet is installed by machinists and toolroom technicians as part of a TG/PG 75 collet chuck assembly to securely grip cutting tools or workpiece stock during machining operations.

This collet is suited for use in vertical and horizontal machining centers, CNC mills, and manual knee mills equipped with TG/PG 75 collet chucks. Typical applications include end mill and drill shank retention where low runout and repeatable tool holdout are priorities. It is appropriate for both production-floor and toolroom environments. The 0.5 inch bore size accommodates standard half-inch shank tooling commonly used across general machining, mold work, and fixture building.

Installation Notes

Installation is performed by a machinist or toolroom technician. Before installing or removing the collet, ensure the machine spindle is fully stopped and the machine is powered down or in a safe lockout state. Use the appropriate TG/PG 75 collet nut and spanner wrench rated for this chuck series. Inspect the collet bore and chuck taper for chips or debris before seating to avoid false TIR readings or premature collet wear.
