Centaur 50023 Tg/pg 75 Standard Single Angle Collet 7/16

Product Description

The CENTAUR 50023 is a standard single angle collet in the TG/PG 75 series, designed to securely grip round workpieces or tooling shanks in compatible collet chucks used in machining and toolholding applications. The collet holds a 0.4375 inch (7/16 inch) bore size and delivers a total indicator runout (TIR) of 0.0005 inches, providing the concentricity required for precision turning, milling, and drilling operations. With a body diameter of 1.06 inches and an overall length of 1.84 inches, this collet fits within the TG/PG 75 form factor standard. It is installed and serviced by machinists and toolroom technicians working with TG/PG 75 collet chuck systems.

The CENTAUR 50023 is suited for production and job-shop machining environments where consistent gripping force and low runout are required. The TG/PG 75 series is a widely used collet format found in vertical machining centers, knee mills, and manual lathes equipped with TG/PG 75 collet chucks. This collet is appropriate for both light finishing passes and moderate material-removal operations where tool concentricity directly affects surface finish and part tolerance.

Key Features

• TG/PG 75 collet series — fits standard TG/PG 75 chuck bodies
• 0.4375 inch (7/16 inch) bore capacity for round shanks and workpieces
• 0.0005 inch TIR for precise concentricity in critical machining operations
• 1.06 inch maximum body diameter within TG/PG 75 form factor
• 1.84 inch overall length for correct seating depth in compatible chucks
• Single angle collet design for consistent clamping along the collet taper

Compatibility

Designed as an OEM-style replacement and standard tooling collet for TG/PG 75 series collet chuck systems requiring a 0.4375 inch bore size.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before installing or removing this collet, ensure the machine spindle is fully stopped and the chuck is secured or removed from the spindle per the machine manufacturer's procedure. Inspect the collet bore and chuck taper for chips or burrs before seating. Do not exceed the rated bore size by forcing oversized tooling into the collet, as this will damage the collet taper and compromise runout.
