Centaur 70039 Tg Pg 100 Standard Single Angle Collet

Product Description

The CENTAUR 70039 is a standard single angle collet designed for use in TG/PG 100 collet systems. It accepts a 0.6875 inch (11/16 inch) bore diameter and delivers a total indicator runout (TIR) of 0.0005 inches, making it suitable for precision workholding applications where concentricity matters. The collet measures 2.38 inches in overall length with a maximum body diameter of 1.38 inches. Machining professionals and toolroom technicians install this collet into compatible TG/PG 100 toolholders on lathes, mills, and grinders where accurate, repeatable clamping of round stock or tooling shanks is required.

This collet fits into TG/PG 100 series toolholding systems used in general machining, production turning, and precision grinding operations. It is appropriate for both manual and CNC machine applications where a standard single angle collet style is specified. The 11/16 inch bore size accommodates round workpieces or tool shanks of that diameter. Typical users include machinists, toolroom technicians, and production operators working with TG/PG 100 compatible spindles and holders.

Key Features

• TG/PG 100 collet series for broad compatibility with standard toolholders in that series
• 0.6875 inch (11/16 inch) bore diameter for precise workpiece or shank clamping
• 0.0005 inch TIR for high concentricity and repeatable runout performance
• 1.38 inch maximum body diameter fits standard TG/PG 100 holder bores
• 2.38 inch overall length suits typical spindle depth requirements
• Single angle collet design for straightforward installation and removal

Compatibility

Designed as an OEM-style replacement or direct-fit collet for TG/PG 100 series toolholding systems requiring a standard single angle collet with a 0.6875 inch bore.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians familiar with collet toolholding systems. Always power down and lock out the machine spindle before installing or removing the collet. Ensure the collet bore, holder taper, and collet nut are clean and free of chips or debris before assembly. Follow the machine manufacturer's recommended torque procedure for the collet nut to avoid distortion of the collet body.
