Value Collection 230-4118 5C Round Steel Collet 9/32 in

Product Description

The VALUE COLLECTION 230-4118 is a 5C-style round steel collet designed for use in 5C-compatible lathes, collet chucks, and workholding fixtures. Manufactured from steel with a total indicator runout (TIR) of 0.0005 inches, this collet provides accurate, repeatable clamping for round workpieces measuring 9/32 inches in diameter. The internal thread measures 1.041 inches-24 and the external thread measures 1.242 inches-20, conforming to standard 5C dimensional specifications. It is suited for production turning, grinding setups, and precision machining operations where consistent concentricity is required.

This collet is used in machine shops running 5C-compatible spindles and workholding equipment. Typical applications include CNC lathes, manual engine lathes, collet blocks, and index fixtures. The round profile makes it appropriate for holding cylindrical bar stock or turned components at 9/32 inch diameter. Both job shop and production environments rely on 5C collets for fast, accurate part changeover without sacrificing runout performance.

Key Features

• 0.0005 inch TIR for precise concentricity in turning and grinding operations
• Steel construction for durability under repeated clamping cycles
• Internal thread size: 1.041 inches-24 per 5C standard
• External thread size: 1.242 inches-20 per 5C standard
• Compatible with the broad range of 5C-pattern spindles and fixtures

Compatibility

Designed as a standard 5C-pattern replacement collet for use in any 5C-compatible lathe spindle, collet chuck, or workholding fixture accepting round collets at 9/32 inch bore size.

Installation Notes

Installation should be performed by a qualified machinist following the machine manufacturer's collet seating and torque procedures. Ensure the spindle or chuck is fully de-energized and the machine is locked out before inserting or removing the collet. Inspect the collet bore and spindle taper for chips, burrs, or wear before seating, as contamination will increase runout. Do not exceed the collet's rated clamping range, as over-tightening on undersized stock can permanently deform the collet body.
