Accupro 784542 Tg/pg 75 Single Angle Collet 5/16 Inch

Product Description

The ACCUPRO 784542 is a standard single angle collet in the TG/PG 75 series, designed for use in TG/PG 75 style toolholders on milling machines, machining centers, and CNC equipment. This collet accepts a 5/16 inch (0.3125 inch) shank diameter and features a maximum body diameter of 1.063 inches with an overall length of 1.844 inches. It holds a total indicator runout (TIR) of 0.00078 inches (0.0200 mm), providing the precision concentricity that machining applications demand. Installation is performed by qualified machinists and toolroom technicians as part of standard toolholder setup.

This collet is suited for use in production machining environments where TG/PG 75 toolholders are standard equipment. Typical applications include milling, drilling, and reaming operations on both vertical and horizontal machining centers. The 5/16 inch bore size accommodates common round-shank cutting tools and workholding accessories within that diameter range. This collet ships individually and is sold in a minimum order quantity of one.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Before changing or seating collets, ensure the machine spindle is fully stopped and the toolholder is removed from the machine. Inspect the collet bore and toolholder taper for debris or damage before assembly. Proper torque on the collet nut should follow the toolholder manufacturer specifications to avoid over-clamping or under-clamping.
