Centaur 70047 TG100 PG100 Single Angle Collet 0.8125 in

Product Description

The CENTAUR 70047 is a standard single angle collet designed for use with TG100 and PG100 collet systems. It accepts a 13/16-inch (0.8125-inch) bore and delivers a total indicator runout (TIR) of 0.0005 inches, providing the precision required for demanding machining applications. The collet measures 2.38 inches in overall length and has a maximum body diameter of 1.38 inches. It is suited for CNC machining centers, milling machines, and grinding operations where accurate workholding and repeatable tool holding are critical. Licensed machinists and toolroom technicians are the primary installers of this type of collet.

The 70047 is used in machine tool setups that call for TG100 or PG100 collet chucks. Its standard single angle design makes it appropriate for production machining environments requiring consistent gripping force and minimal runout. Typical applications include milling, drilling, reaming, and tapping operations where tool concentricity directly affects part quality. The collet is packaged individually and ordered in single-unit quantities, making it practical for both replacement and initial setup needs.

Key Features

• TG100 and PG100 series compatibility for broad collet chuck fitment
• 0.0005-inch TIR for high-precision tool or workholding applications
• 0.8125-inch (13/16-inch) bore size for standard tooling diameters
• 1.38-inch maximum body diameter for use in standard TG100 chuck bores
• 2.38-inch overall length suited to typical collet chuck depth requirements
• Standard single angle design for reliable clamping and release

Compatibility

Designed for use with TG100 and PG100 collet chuck systems requiring a 0.8125-inch bore collet.

Installation Notes

Collet installation should be performed by a qualified machinist or toolroom technician. Before inserting or removing the collet, ensure the machine spindle is fully stopped and locked out per applicable OSHA lockout/tagout procedures. Clean the collet and chuck bore thoroughly before seating to avoid runout caused by debris. Do not force the collet into the chuck; proper engagement should require only hand pressure followed by the appropriate draw nut torque per the chuck manufacturer's specification.
