Accupro 784570 Tg/pg 75 Standard Single Angle Collet

Product Description

The ACCUPRO 784570 is a standard single angle collet designed for use in TG/PG 75 collet chuck systems. It accepts tooling with a 0.75 inch (3/4 inch) shank diameter and delivers a total indicated runout (TIR) of 0.00078 inches (0.0200 mm), making it suitable for precision machining applications where concentricity matters. The body diameter measures 1.063 inches and the overall length is 1.844 inches. This collet is installed by machinists and toolroom technicians working with milling machines, CNC machining centers, and similar spindle-driven equipment that use the TG/PG 75 toolholding standard.

This collet fits TG/PG 75 series collet chucks used in production and precision machining environments. It is appropriate for both manual and CNC machine tool setups where a 0.75 inch shank must be held with minimal runout. The standard single angle profile seats into compatible TG/PG 75 chuck bodies. Typical applications include end mill holding, reamer holding, and drill holding where repeatable grip and low TIR are required.

Key Features

• TG/PG 75 collet series for compatibility with standard TG/PG 75 chuck bodies
• 0.75 inch (3/4 inch) clamping diameter for common shank sizes
• Low TIR of 0.00078 inches (0.0200 mm) for precision concentricity
• Maximum body diameter of 1.063 inches
• Overall length of 1.844 inches for standard reach in TG/PG 75 chucks
• Lightweight at 0.2 pounds — minimal contribution to spindle load

Compatibility

Designed for use with TG/PG 75 series collet chuck bodies that accept standard single angle collets with a 0.75 inch bore.

Installation Notes

Installation is performed by machinists or toolroom technicians. Power down and lock out the machine spindle before inserting or removing collets. Ensure the collet bore, shank, and chuck body are clean and free of chips or debris before seating, as contamination directly affects TIR. Use the appropriate collet nut wrench for the TG/PG 75 chuck to achieve proper clamping torque — do not use pipe wrenches or improvised tools on the collet nut.
