Parlec 100PG-0843 Tg Pg 100 Single Angle Collet 0.8438 in

Product Description

The PARLEC 100PG-0843 is a standard single angle collet in the TG/PG 100 series, designed for precision workholding in CNC machining and milling applications. It accepts a 0.8438-inch bore diameter and delivers a total indicator runout (TIR) of 0.0005 inches, making it suitable for operations where concentricity and repeatability are critical. The collet measures 2.375 inches overall length with a maximum body diameter of 1.379 inches. It is installed by machinists and toolroom technicians into compatible TG/PG 100 collet chucks on machining centers and milling machines.

This collet is used in production and toolroom environments where the TG/PG 100 collet system is the standard toolholding platform. Typical applications include end milling, drilling, and reaming operations on vertical and horizontal machining centers. The 0.8438-inch (27/32 inch) bore size accommodates tooling shanks at that diameter. This part is suited for both high-volume production shops and precision toolroom use where consistent gripping force and low runout are required.

Key Features

• TG/PG 100 collet series for compatibility with standard TG/PG 100 chucks
• 0.8438-inch bore diameter accepts 27/32-inch shank tooling

Compatibility

Designed as an OEM-style replacement and standard fit for TG/PG 100 series collet chucks used on CNC machining centers and milling machines.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. The machine spindle must be fully stopped and locked out before inserting or removing collets from the chuck. Clean the collet bore and chuck taper thoroughly before seating to ensure accurate runout. Follow the chuck manufacturer's torque procedure using the appropriate spanner wrench - do not use impact tools on collet nuts.
