Centaur 50042 TG75 PG75 Standard Single Angle Collet 47/64

Product Description

The CENTAUR 50042 is a standard single angle collet designed for use in TG75 and PG75 collet systems. It provides secure, repeatable workpiece clamping in precision machining applications where tight tolerances are required. The 50042 holds a 0.7344 inch (47/64 inch) bore size with a total indicator runout (TIR) of 0.0005 inches, making it suitable for applications where concentricity directly affects finished part quality. The body diameter measures 1.06 inches with an overall length of 1.84 inches. Machinists and toolroom technicians install this collet in compatible spindle systems to maintain accurate tool or workpiece positioning during turning, grinding, or milling operations.

This collet is used in machine shop environments where TG75 or PG75 spindle tooling systems are in service. It is suited for both production and toolroom settings where repeatable grip and low runout are priorities. The 47/64 inch bore size accommodates round stock or tooling shanks at that diameter. Typical applications include CNC turning centers, manual lathes, and grinding machines equipped with TG75 or PG75 compatible spindle noses or collet chucks.

Key Features

• 0.7344 inch (47/64 inch) bore capacity for precise workpiece or tooling shank fitment
• TIR of 0.0005 inches for high-concentricity clamping
• 1.06 inch maximum body diameter fits TG75 and PG75 collet systems
• 1.84 inch overall length suits standard collet chuck depth requirements
• Standard single angle collet design for straightforward installation and removal

Compatibility

Designed for use with TG75 and PG75 collet series spindle tooling systems. Verify spindle nose and chuck compatibility with the TG75 or PG75 standard before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with collet chuck systems. Power down and de-energize the machine spindle completely before inserting or removing the collet. Use the appropriate collet wrench or closing nut specified for the TG75 or PG75 system — do not use improvised tools that could damage the collet taper or chuck bore. Inspect the collet bore and chuck pocket for debris or damage before seating to maintain the rated TIR performance.
