Value Collection 1230-4224 5C Round Collet 13.50mm

Product Description

The VALUE COLLECTION 1230-4224 is a 5C round collet machined from steel for use in 5C-compatible spindles and collet chucks on lathes and grinding machines. It accepts a 1.041 inch-24 internal thread and a 1.242 inch-20 external thread, with a collet size of 13.50 mm. Total indicator runout (TIR) is rated at 0.015 mm, making it suitable for precision turning and grinding operations where concentricity matters. Licensed machinists and toolroom technicians are the primary installers of this workholding component.

This 5C round collet is used in machine shops and toolrooms running standard 5C spindle setups on engine lathes, chucker lathes, and surface grinders. It is appropriate for both production and job-shop environments where repeatable, accurate workholding on round stock is required. The 13.50 mm collet size accommodates round workpieces at that nominal diameter.

Key Features

• 5C round collet profile for use in standard 5C spindle and chuck systems
• Steel construction for durability in continuous machining environments
• TIR of 0.015 mm for precise concentricity during turning and grinding
• 1.041 inch-24 internal thread and 1.242 inch-20 external thread for proper spindle engagement
• 13.50 mm collet size suits common round workpiece diameters

Compatibility

Designed as an OEM-style replacement or direct fitment for 5C collet-compatible spindles and chucks on lathes and cylindrical grinding machines that accept the standard 5C collet form factor.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Before inserting or removing the collet, the machine spindle must be fully stopped and the drive isolated. Inspect the collet bore and spindle taper for burrs or debris before seating, as contamination will degrade runout performance. Do not force a collet into a spindle that does not thread smoothly by hand.
