Lyndex-nikken 164-064 Square Collet 1 Inch

Product Description

The LYNDEX-NIKKEN 164-064 is a square collet designed for precision workholding in CNC machining and toolholding applications. It accepts 1-inch square stock and features an internal thread size of 1-11/16 inch-20 along with an M47.5 x 1.75 external thread for secure mounting in compatible collet chucks. The overall length (OAL) measures 4.31 inches and the total indicator runout (TIR) is held to 0.0011 inches, making it suitable for applications where concentricity and repeatability are critical. Licensed machinists and CNC setup technicians are the primary installers of this component.

This square collet is used in machine shop environments where square-profile stock or tooling must be held with minimal runout. It fits into collet chuck bodies that accept the corresponding external thread specification. Typical applications include milling, turning centers, and precision grinding setups where non-round workpiece profiles require a dedicated square collet rather than a standard round collet. Both production shop floors and tool-and-die operations rely on this type of collet for consistent, repeatable clamping of square stock.

Key Features

• 1-inch square collet size for holding square-profile stock or tooling
• TIR of 0.0011 inches for high-precision, low-runout performance
• Internal thread size of 1-11/16 inch-20 for secure chuck engagement
• M47.5 x 1.75 external thread for compatibility with matching collet chuck bodies
• 4.31-inch overall length provides adequate reach for standard CNC setups

Compatibility

Designed for use with collet chuck systems that accept an M47.5 x 1.75 external thread interface. Consult the collet chuck manufacturer specifications to confirm thread and bore compatibility before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician familiar with collet chuck systems. Ensure the machine spindle is fully de-energized and any rotational motion has completely stopped before handling or replacing collets. Threads should be clean and free of chips or debris prior to installation. Do not exceed the collet chuck manufacturer's recommended clamping torque range for this thread specification.
