Parlec 75PG-0640 Tg/pg 75 Single Angle Collet 0.6406 in

Product Description

The PARLEC 75PG-0640 is a standard single angle collet designed for use in TG/PG 75 series collet chucks on CNC machining centers and manual milling machines. It accepts a 0.6406 inch (41/64 inch) workpiece or toolholder shank, features a maximum body diameter of 1.062 inches, and has an overall length of 1.844 inches. Total indicator runout (TIR) is held to 0.0005 inches, delivering the concentricity accuracy required for precision turning, milling, and drilling operations. This collet is installed by machinists and toolroom technicians working in production or job-shop environments.

This collet is suited for both production and prototype machining applications where a TG/PG 75 series chuck is already in use. The 41/64 inch bore size accommodates tooling shanks and workpiece stock at that diameter. It is appropriate for light to moderate cutting loads on vertical and horizontal machining centers as well as manual knee mills equipped with a compatible TG/PG 75 chuck body.

Key Features

• TG/PG 75 series collet - fits standard TG/PG 75 chuck bodies
• 0.6406 inch (41/64 inch) bore for precision shank or stock clamping
• 0.0005 inch TIR for consistent concentricity across the cutting edge
• 1.062 inch maximum body diameter fits TG/PG 75 bore specifications
• 1.844 inch overall length provides standard reach in the chuck
• Single angle collet design for positive grip and repeatable seating

Compatibility

Designed as an OEM-style replacement or direct-fit collet for TG/PG 75 series collet chucks accepting a 0.6406 inch bore size.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. The machine spindle must be fully stopped and the chuck body secured before inserting or removing collets. Clean the chuck bore and collet taper mating surfaces before seating to ensure full contact and accurate TIR. Refer to the chuck manufacturer torque guidelines for the drawbar or clamping nut - do not estimate clamping force by feel alone.
