Parlec 100PG-0859 Tg Pg 100 Single Angle Collet 0.8594in

Product Description

The PARLEC 100PG-0859 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, mills, and drilling equipment. It accepts a 0.8594 inch (55/64 inch) bore and provides a total indicator runout (TIR) of 0.0005 inches, making it suitable for precision toolholding applications where concentricity directly affects finished part quality. The body diameter measures 1.379 inches with an overall length of 2.375 inches. Installation and removal are handled by machinists and toolroom technicians as part of routine toolholder setup and changeover.

This collet is intended for use in machining environments where TG/PG 100 series toolholding systems are in service. Typical applications include production milling, drilling, reaming, and tapping operations in both job shop and high-volume manufacturing settings. The 55/64 inch bore size accommodates tooling shanks at that diameter. The TG/PG 100 platform is a widely adopted single-angle collet standard used across a broad range of vertical and horizontal machining center spindles configured for this series.

Key Features

• 0.8594 inch (55/64 inch) bore diameter for precise shank fit
• TIR of 0.0005 inches for high concentricity toolholding
• 1.379 inch maximum body diameter for TG/PG 100 chuck compatibility
• 2.375 inch overall length for standard reach in TG/PG 100 holders
• Standard single angle collet geometry for secure gripping and repeatable seating

Compatibility

Designed for use with TG/PG 100 series collet chucks and toolholders accepting the standard single angle collet geometry at a 0.8594 inch bore size.

Installation Notes

Installation is performed by machinists or toolroom technicians during toolholder assembly or changeover. Power down and lock out all machine spindles before inserting or removing collets. Use the appropriate TG/PG 100 collet nut and spanner wrench rated for this series. Inspect the collet bore and chuck taper for chips or damage before seating to preserve TIR performance.
