Accupro 784538 Tg/pg 75 Single Angle Collet 0.25 in

Product Description

The ACCUPRO 784538 is a standard single angle collet designed for use with TG/PG 75 collet systems. It accepts a 0.25-inch bore and delivers a Total Indicator Runout (TIR) of 0.00078 inches (0.02 mm), making it suitable for precision machining applications where concentricity matters. The collet measures 1.063 inches in maximum body diameter and 1.844 inches in overall length. It is installed by machinists and toolroom technicians in CNC machining centers, milling machines, and manual mills equipped with TG/PG 75 toolholding systems.

This collet is used in production and job-shop environments where consistent grip and low runout are required for end mills, drills, and other round-shank cutting tools with a 0.25-inch shank. The TG/PG 75 series is a common toolholding standard found in both vertical and horizontal machining centers. It is appropriate for light to moderate material removal operations where tool rigidity and repeatability are essential to maintaining part tolerances.

Key Features

• 0.25-inch bore accommodates quarter-inch round-shank tooling
• TIR of 0.00078 inches (0.02 mm) for precision concentricity
• Maximum body diameter of 1.063 inches fits TG/PG 75 toolholders
• Overall length of 1.844 inches (46.83 mm)
• Standard single angle collet geometry for reliable clamping force

Compatibility

Designed as a direct-fit replacement collet for TG/PG 75 series toolholders requiring a 0.25-inch bore capacity.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Always power down and lock out the spindle drive before removing or installing collets. Inspect the collet bore and toolholder taper for chips, burrs, or wear before seating the collet. Use the appropriate collet nut and torque wrench rated for the toolholder series per the machine manufacturer specifications.
