Centaur 70050 TG100 PG100 Standard Single Angle Collet 0.8594 in

Product Description

The CENTAUR 70050 is a standard single angle collet designed for use in TG100 and PG100 collet systems. It accepts a 0.8594-inch (55/64-inch) round workpiece or cutting tool shank and delivers a total indicator runout (TIR) of 0.0005 inches, providing the concentricity that precision machining operations demand. With a body diameter of 1.38 inches and an overall length of 2.38 inches, this collet fits standard TG100 and PG100 spindle noses and collet chucks. Machinists, toolroom technicians, and CNC setup personnel install this collet when holding drills, end mills, reamers, or round-shank tools in compatible toolholding systems.

This collet is suited for production and toolroom environments where consistent tool runout and secure clamping are required. It is a standard-profile, single-angle design intended for use in vertical and horizontal machining centers, mills, and drill presses equipped with TG100 or PG100 collet chucks. Its 55/64-inch nominal bore makes it a common choice for holding standard fractional and metric-equivalent shank tooling in that size range.

Key Features

• 0.0005-inch TIR for high concentricity in precision toolholding applications
• 0.8594-inch (55/64-inch) bore accepts standard fractional shank tooling
• Compatible with both TG100 and PG100 collet chuck systems
• 1.38-inch body diameter fits standard TG100/PG100 collet chuck bores
• 2.38-inch overall length for proper engagement depth in the chuck
• Standard single angle design for straightforward installation and removal

Compatibility

Designed for use in TG100 and PG100 collet chuck systems accepting standard single angle collets with a 0.8594-inch bore.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before inserting or removing the collet, ensure the machine spindle is fully stopped and the chuck is de-energized or disengaged. Clean the collet and chuck bore thoroughly before seating the collet to prevent runout caused by debris. Tighten the collet nut to the toolholder manufacturer's recommended procedure using a spanner wrench; do not use pipe extensions or impact tools on the collet nut.
