Value Collection 230-4113 5C Steel Collet 13/64 in

Product Description

The VALUE COLLECTION 230-4113 is a 5C steel collet designed for use in 5C-compatible spindles and collet chucks found on lathes, grinders, and milling machines. This round-bore collet holds a 13/64 inch workpiece and is machined to a total indicator runout (TIR) of 0.0005 inches, providing the concentricity required for precision turning and grinding operations. The internal thread measures 1.041 inches at 24 threads per inch, and the external thread measures 1.242 inches at 20 threads per inch. It is constructed from steel for durability under repeated clamping cycles. Machinists and toolroom technicians are the primary installers of this component.

This collet is suited for production and toolroom environments where 5C-style workholding is the standard. Typical applications include holding round bar stock for turning operations, positioning parts for secondary operations, and securing workpieces for grinding. The 13/64 inch bore size targets small-diameter work common in precision machining, instrument manufacturing, and job-shop environments. Single-piece packaging makes it straightforward to replace a worn or damaged collet in an existing 5C setup without purchasing a full set.

Key Features

• 13/64 inch round bore for small-diameter workpiece holding
• 0.0005 inch TIR for high concentricity in precision operations
• 1.041 inch-24 internal thread matches standard 5C spindle nose dimensions
• 1.242 inch-20 external thread for proper collet chuck engagement
• Steel construction resists deformation under repeated clamping loads

Compatibility

Designed as an OEM-style replacement or spare for machinery equipped with standard 5C-style collet spindles and chucks.

Installation Notes

A licensed machinist or qualified toolroom technician should install and seat this collet. Always de-energize and lock out the machine spindle before removing or installing any collet. Inspect the spindle bore and collet surfaces for chips or burrs prior to installation, as contamination will directly affect runout. Do not overtighten the draw tube or closer; follow the machine manufacturer's torque guidance for the specific spindle in use.
