Parlec 75PG-0250 Tg Pg 75 Single Angle Collet 0.25 in

Product Description

The PARLEC 75PG-0250 is a standard single angle collet in the TG/PG 75 series, designed for precision workholding in CNC machining and manual milling applications. It accepts a 0.25-inch round shank tooling and delivers a total indicator runout (TIR) of 0.0005 inches, supporting tight-tolerance cutting operations where concentricity matters. With a body diameter of 1.062 inches and an overall length of 1.844 inches, this collet fits directly into TG/PG 75 collet chucks without modification. It is installed by machinists and toolroom technicians on machining centers, mills, and drilling equipment.

This collet is suited for production and toolroom environments that require consistent, repeatable tool clamping in TG/PG 75 compatible chucks. Typical applications include end milling, drilling, and reaming where a 0.25-inch bore size is required. The single angle design is the standard configuration for TG/PG 75 series chucks and is commonly used in both job shop and high-volume CNC production settings.

Key Features

• 0.25-inch bore size for standard quarter-inch shank tooling
• TIR of 0.0005 inches for high-concentricity tool holding
• 1.062-inch maximum body diameter fits TG/PG 75 chuck pockets
• 1.844-inch overall length suits standard chuck stack-up requirements
• Standard single angle collet geometry for broad TG/PG 75 compatibility

Compatibility

Designed for use with TG/PG 75 series collet chucks requiring a standard single angle collet with a 0.25-inch bore.

Installation Notes

Installation is performed by a machinist or toolroom technician. De-energize and lock out the machine spindle before inserting or removing the collet. Ensure the chuck bore and collet exterior are clean and free of chips or debris before seating the collet, as contamination will degrade TIR performance. Torque the chuck retention nut according to the chuck manufacturer specifications, not general estimates.
