Centaur 70023 Tg Pg 100 Standard Single Angle Collet 7/16

Product Description

The CENTAUR 70023 is a standard single angle collet in the TG/PG 100 series, designed for use in TG/PG 100 collet chucks on CNC machining centers, lathes, and toolroom mills. This collet accepts a 0.4375-inch (7/16) shank diameter and delivers a true indicated runout (TIR) of 0.0005 inches, making it well suited for precision boring, milling, drilling, and reaming operations. With an overall length of 2.38 inches and a maximum body diameter of 1.38 inches, the 70023 fits standard TG/PG 100 toolholding systems and provides consistent grip force across the clamping range. Machining technicians and toolroom operators install this collet as part of a standard toolholder assembly.

The CENTAUR 70023 is appropriate for production and toolroom environments where accurate tool centerline control is required. It is used in both manual and CNC machine tools equipped with TG/PG 100 toolholding systems. Common applications include high-speed spindle work where runout control directly affects surface finish and tool life. The collet is sold individually, making it a practical replacement or addition to an existing TG/PG 100 collet set.

Key Features

• TG/PG 100 series collet — compatible with standard TG/PG 100 chucks and toolholders
• 0.4375-inch (7/16) clamping diameter for round-shank tooling
• 0.0005-inch TIR for precision tool centerline control
• 1.38-inch maximum body diameter fits standard TG/PG 100 chuck bores
• 2.38-inch overall length provides standard projection for typical toolholder assemblies
• Single-piece collet construction — no loose components

Compatibility

Designed as a standard replacement or additional collet for TG/PG 100 series collet chucks and toolholders accepting a 0.4375-inch clamping diameter.

Installation Notes

Installation is performed by machining technicians or toolroom personnel. Always power down and lock out the machine spindle before inserting or removing collets. Inspect the collet bore, chuck taper, and clamping nut for chips, wear, or damage before assembly. Use the correct TG/PG 100 spanner wrench and clamping nut — do not substitute tooling from other collet series, as taper geometry and clamping angles differ between series.
