Value Collection 1230-4223 5C Round Collet 13.00 Mm Steel

Product Description

The VALUE COLLECTION 1230-4223 is a 5C round collet designed for use in collet chucks, collet closers, and compatible workholding fixtures found on lathes and other rotating machine tool spindles. Machined from steel, this collet holds round stock and is sized at 13.00 mm. It features an internal thread of 1.041 inches-24 and an external thread of 1.242 inches-20, allowing it to seat and draw correctly in standard 5C-compatible spindle noses and closers. Total Indicated Runout (TIR) is rated at 0.015 mm, providing repeatable concentricity suitable for precision turning and chucking operations. Machinists and toolroom technicians are the typical end users for this type of workholding component.

This 5C round collet is intended for use in machine shop environments where 5C collet systems are the standard workholding method. Typical applications include bar stock turning, second-operation chucking, and light milling when mounted in a 5C-compatible fixture or indexer. The round profile accommodates cylindrical workpieces. This collet is suited for both production and toolroom environments running manual or CNC lathes equipped with a 5C spindle nose or collet closer.

Key Features

• 5C round collet format fits standard 5C spindle noses and collet closers
• 13.00 mm collet size for round stock workholding
• Steel construction for rigidity and durability under lathe cutting loads
• TIR of 0.015 mm for repeatable concentricity in precision turning operations
• Internal thread: 1.041 inches-24 for proper draw-tube engagement
• External thread: 1.242 inches-20 for correct seating in the spindle nose

Compatibility

Designed as an OEM-style replacement or standard component for machine tools equipped with a 5C collet system, including lathes, collet closers, and 5C indexing fixtures that accept round 5C collets.

Installation Notes

Installation and removal of 5C collets should be performed by a qualified machinist with the spindle fully stopped and the machine locked out per applicable safety procedures. Inspect the collet bore, external taper, and threads for chips or damage before seating. Do not force a collet into a closer or spindle nose; proper thread engagement should be smooth and free of resistance. Follow the machine manufacturer guidelines for collet closer draw force to avoid distorting the collet.
