Value Collection 530-4244 5C Square Collet 11/16 Inch

Product Description

The VALUE COLLECTION 530-4244 is a 5C square collet machined from steel for use in 5C-compatible spindles and collet closers on lathes, collet chucks, and indexing fixtures. Designed to grip square stock at 11/16 inch across flats, this collet provides a true indicator reading (TIR) of 0.0005 inches, supporting accurate, repeatable workholding in production and toolroom environments. The internal thread measures 1.041 inches-24 and the external thread measures 1.242 inches-20, conforming to standard 5C geometry. Machinists and tool-room operators install this collet when turning, facing, or secondary-machining square bar stock that requires precise concentricity and secure clamping.

This collet is suited for use in manual lathes, CNC turning centers, and rotary indexing heads equipped with a 5C spindle. It is a practical choice in job shops and production environments where square stock in the 11/16 inch size is regularly machined. The steel construction handles the clamping forces and repeated use cycles typical of industrial turning operations. No special tooling beyond a standard collet closer or 5C chuck body is required for installation.

Key Features

• Square collet profile grips 11/16 inch square stock securely
• TIR of 0.0005 inches supports accurate, repeatable workholding
• Internal thread: 1.041 inches-24 for standard 5C draw-tube engagement
• External thread: 1.242 inches-20 for standard 5C spindle compatibility
• Steel construction provides durability under repeated clamping cycles

Compatibility

Designed as an OEM-style replacement and standard fitment collet for 5C-compatible spindles, collet closers, collet chucks, and rotary indexing fixtures that accept the 1.242 inches-20 external thread standard.

Installation Notes

Installation is performed by machinists and tool-room technicians familiar with 5C workholding systems. Before inserting or removing the collet, ensure the machine spindle is fully stopped and the collet closer is fully released. Inspect the collet bore and spindle nose for chips or burrs that could affect seating and TIR before tightening the draw tube. Do not exceed the rated clamping force for the collet size, as overloading can distort the collet segments and degrade accuracy.
