Parlec 100PG-0781 Tg/pg 100 Single Angle Collet 0.781

Product Description

The PARLEC 100PG-0781 is a standard single angle collet designed for use with TG100 and PG100 collet systems on CNC machining centers and toolholding setups. It accepts a 0.7813-inch (25/32 inch) bore diameter and delivers a total indicator runout (TIR) of 0.0005 inches, providing the concentricity control required for precision milling, drilling, and reaming operations. The collet measures 2.375 inches overall length with a body diameter of 1.379 inches. It is installed and serviced by machinist-level technicians and toolroom personnel working with collet chuck assemblies in production or job-shop environments.

This collet is suited for use in machining centers, mills, and drill presses that accept TG100 or PG100 collet nut and chuck systems. The single angle design provides consistent gripping force across the bore, making it appropriate for through-coolant and standard cutting tool applications. A bore size of 0.7813 inches covers a range of common shank diameters used in end mills, drill bits, and reamers in that size class.

Installation Notes

Installation is performed by qualified toolroom or machining personnel. Always power down and lock out the machine spindle before changing or seating collets. Inspect the collet bore and chuck taper for chips, burrs, or contamination prior to assembly, as debris will directly affect runout. Use the appropriate collet nut torque procedure per the chuck manufacturer's guidelines and verify TIR with a dial indicator after seating.
