Accupro 784558 Tg/pg 75 Standard Single Angle Collet

Product Description

The ACCUPRO 784558 is a standard single angle collet designed for use in TG/PG 75 collet systems. It accepts a 0.5625 inch (9/16 inch) bore diameter and delivers a total indicator runout (TIR) of 0.00078 inches, making it suitable for precision machining applications where concentricity matters. The maximum body diameter measures 1.063 inches and overall length is 1.844 inches. This collet is installed by machinists and toolroom technicians working with TG 75 or PG 75 toolholders on milling machines, machining centers, and similar CNC or manual equipment.

The 784558 is used in production and job-shop environments where consistent grip and low runout are required for end mills, drills, reamers, and other round-shank cutting tools. The TG/PG 75 series is a commonly specified collet format in industrial machining setups. This collet is sold individually and is appropriate for shops sourcing replacement or additional collets to expand their TG 75 toolholder inventory.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Before changing collets, confirm the spindle is fully stopped and the machine is in a safe, powered-down state. Inspect the collet and toolholder bore for debris, nicks, or wear before seating the collet. Tighten the collet nut to the toolholder manufacturer's recommended procedure using an appropriate spanner wrench — do not use improvised tools that could damage the nut or collet.
