Accupro 784539 Single Angle Collet Tg/pg 75 0.2656 in

Product Description

The ACCUPRO 784539 is a standard single angle collet built to the TG/PG 75 collet series specification. It accepts a 17/64-inch (0.2656-inch) bore size and delivers a Total Indicator Runout (TIR) of 0.00078 inches, making it suitable for precision CNC turning and milling operations where concentricity matters. The body diameter measures 1.063 inches and the overall length (OAL) is 1.844 inches. This collet is installed by machinists and CNC operators in production and job-shop environments where consistent grip force and low runout are required to hold cutting tools or workpieces accurately.

The 784539 is designed for use in TG/PG 75 collet chucks and toolholders on CNC machining centers, lathes, and manual machine tools that accept the TG/PG 75 series. The 17/64-inch bore makes it appropriate for holding tool shanks or round stock at that exact diameter. This collet is well-suited for light-to-medium material removal operations in both production and prototype machining environments. It is sold individually and typically stocked as part of a matched collet set covering a range of bore sizes within the TG/PG 75 family.

Key Features

• TG/PG 75 series collet standard for broad toolholder compatibility within the series
• 0.00078-inch TIR for precise concentricity during cutting operations
• 17/64-inch (0.2656-inch) bore size for direct tool or workpiece engagement
• 1.063-inch maximum body diameter fits TG/PG 75 chuck bore specs
• 1.844-inch overall length provides adequate clamping engagement depth

Compatibility

Designed for use with TG/PG 75 series collet chucks and toolholders that accept the standard single angle collet configuration.

Installation Notes

Installation is performed by machinists or CNC setup technicians. The machine spindle must be fully stopped and locked before inserting or removing collets. Collet and chuck mating surfaces should be clean and free of chips or oil before assembly to ensure proper seating and accurate TIR. Do not force the collet into the chuck; hand pressure followed by the appropriate draw nut torque per the chuck manufacturer specification is the correct procedure.
