Value Collection 230-4215 5C Round Collet 15mm Steel

Product Description

The VALUE COLLECTION 230-4215 is a 5C round collet machined from steel for use in 5C-compatible spindles on lathes and other workholding equipment. It accepts round stock and is sized at 15.00 mm, making it suitable for gripping cylindrical workpieces during turning, milling, 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. Total indicated runout (TIR) is rated at 0.015 mm, providing the concentricity required for precision turning work. Machinists and tool-room operators are the primary installers.

This collet is intended for use in manual lathes, CNC turning centers, collet chucks, and indexing fixtures that accept the standard 5C collet format. The 5C system is widely used in production and job-shop environments for both light and medium-duty workholding. It is suited for residential shop, commercial machine shop, and industrial production settings where consistent grip and repeatable runout are required.

Installation Notes

Installation is performed by qualified machinists or tool-room personnel. Before inserting or removing the collet, confirm the spindle is fully stopped and the machine is powered down or locked out per applicable safety procedures. Inspect the collet bore and spindle taper for chips or burrs before seating the collet, as debris can increase runout. Do not exceed the rated collet capacity when clamping workpieces, as overloading can damage the collet or reduce clamping accuracy.
