Parlec 100PG-0875 TG100 PG100 Single Angle Collet 7/8

Product Description

The PARLEC 100PG-0875 is a standard single angle collet designed for TG100 and PG100 collet chucks used in precision CNC machining and toolholding applications. It accepts a 0.875 inch (7/8 inch) tool or workpiece shank and delivers a total indicator runout (TIR) of 0.0005 inches, making it suitable for applications where concentricity and repeatability are critical. The overall length is 2.375 inches with a maximum body diameter of 1.379 inches. Machinists, CNC operators, and toolroom technicians install this collet when setting up milling, drilling, or tapping operations that require a secure, accurate tool grip in a TG or PG style chuck.

This collet is intended for use in machining centers, knee mills, and toolroom equipment equipped with TG100 or PG100 style collet chucks. It is well suited for production environments where consistent tool runout directly affects surface finish and hole accuracy. Shops running high-volume drilling or tapping cycles commonly use TG100 series collets for their grip force and vibration-damping characteristics compared to standard ER-style collets.

Key Features

• TIR of 0.0005 inches for high-concentricity toolholding
• Overall length of 2.375 inches for standard chuck projection
• Maximum body diameter of 1.379 inches
• Standard single angle collet geometry for broad chuck compatibility

Compatibility

Designed for use with TG100 and PG100 series collet chucks accepting a 0.875 inch bore collet.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before inserting or removing a collet, ensure the spindle is fully stopped and locked out per shop lockout/tagout procedures. Use the appropriate collet nut wrench for the chuck series to achieve proper seating without cross-threading or overtightening. Inspect the collet bore and chuck taper for chips or contamination before assembly to protect TIR performance.
