Centaur 70004 Standard Single Angle Collet TG100 0.1406 in

Product Description

The CENTAUR 70004 is a standard single angle collet designed for use in TG100 and PG100 collet chucks commonly found in CNC machining centers, lathes, and milling machines. This collet holds a 9/64 inch (0.1406 inch) workpiece or cutting tool shank and delivers a total indicated runout (TIR) of 0.0005 inches, providing the concentricity needed for accurate cutting, drilling, and reaming operations. The 1.38 inch body diameter and 2.38 inch overall length conform to standard TG100 series dimensions. Machinists and toolroom technicians working in production or job-shop environments rely on this collet for consistent, repeatable tool holding at light to moderate cutting loads.

This collet is suited for precision metalworking applications where tight TIR tolerances are required. It fits standard TG100 and PG100 collet chuck systems used in both manual and CNC machine tools. Typical installations include vertical machining centers, horizontal machining centers, and toolroom lathes where straight-shank end mills, drills, or reamers with a 0.1406 inch shank diameter need to be held securely. The single angle design seats into the collet chuck with a single tapered contact surface, making installation and removal straightforward during tool changes.

• TIR of 0.0005 inches for high concentricity and accurate cutting
• Compatible with TG100 and PG100 collet chuck systems
• 1.38 inch maximum body diameter conforms to TG100 series standard
• 2.38 inch overall length for proper chuck engagement and tool reach
• Single angle collet design allows quick, repeatable tool changes

Compatibility

Designed as an OEM-style replacement and standard fit for TG100 and PG100 series collet chuck systems. Specific compatible chuck model numbers were not provided in the product data; verify chuck series and bore size against your machine tool specification before ordering.

Installation Notes

Installation and removal should be performed by a qualified machinist or toolroom technician with the machine spindle fully stopped and locked out per the machine tool manufacturer's lockout/tagout procedure. Collet and chuck taper surfaces should be clean and free of chips, coolant residue, and burrs before seating the collet. Use the appropriate spanner wrench or collet nut tool for your TG100 chuck — never use an adjustable wrench or pipe wrench, as this can damage the collet nut and affect runout. Inspect the collet bore and taper for wear or damage before each use to maintain TIR within specification.
