Parlec 75PG-0312 Tg/pg 75 Single Angle Collet 5/16 in

Product Description

The PARLEC 75PG-0312 is a standard single angle collet designed for use in TG/PG 75 collet chucks on CNC machining centers and milling machines. It accepts a 5/16 inch (0.3125 inch) tool shank and delivers a total indicator runout (TIR) of 0.0005 inches, making it well suited for precision work where concentricity matters. The body diameter measures 1.062 inches and the overall length is 1.844 inches. Machinists and toolroom technicians install this collet when holding end mills, drills, reamers, or other round-shank tooling in TG/PG 75 compatible holders.

This collet fits into TG/PG 75 series toolholding systems commonly found in production and job-shop environments running vertical or horizontal machining centers. It is appropriate for general-purpose material removal as well as applications demanding tight runout control. The 5/16 inch bore size makes it a common selection for standard-diameter end mills and drill shanks in that range.

Key Features

• TG/PG 75 collet series for compatibility with standard TG/PG 75 toolholders
• 0.3125 inch (5/16 inch) bore accommodates round-shank cutting tools

Compatibility

Designed as a direct-fit replacement for TG/PG 75 series collet chucks accepting standard single angle collets with a 0.3125 inch bore.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing collets. Clean the collet, nut, and chuck bore thoroughly before assembly to prevent debris from affecting runout. Torque the collet nut according to the toolholder manufacturer specifications to achieve rated TIR performance.
