Centaur 70049 Single Angle Collet TG100 PG100 0.8438 in

Product Description

The CENTAUR 70049 is a standard single angle collet designed for TG100 and PG100 toolholding systems. It accepts a 27/32 inch (0.8438 inch) round shank and provides a maximum total indicator runout (TIR) of 0.0005 inches, making it suitable for precision machining applications where concentricity is critical. With an overall length of 2.375 inches and a maximum body diameter of 1.38 inches, this collet fits within the standard TG/PG 100 series envelope. Machinists and tool crib technicians working with lathes, mills, and CNC equipment install this collet type as a workholding or toolholding component in production and job shop environments.

This collet is intended for use in TG100 and PG100 series collet chucks and toolholders. The TG/PG 100 series is a widely used standard in machining centers and manual machines requiring secure, repeatable clamping of round-shank tooling. It is applicable in both light-duty and moderate-production machining scenarios where accurate tool positioning and minimal runout are required. The 27/32 inch bore size suits a range of end mills, drills, and round-shank cutting tools of that diameter.

Installation Notes

Installation is performed by a machinist or tool crib technician following standard collet chuck assembly procedures. Power down and fully de-energize the machine spindle before installing or removing collets. Ensure the collet, chuck bore, and clamping nut are clean and free of chips or debris before assembly, as contamination directly affects runout. Follow the machine and chuck manufacturer torque guidelines for the clamping nut to achieve rated TIR performance.
