Value Collection 1230-4244 5C Round Collet 23.50mm

Product Description

The VALUE COLLECTION 1230-4244 is a 5C round collet machined from steel, designed for use in 5C-compatible spindles, collet chucks, and indexing fixtures found in machine shop environments. It accepts round workpieces at a collet size of 23.50mm and holds a total indicated runout (TIR) of 0.015mm, making it suitable for turning, grinding, and other precision workholding 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. Machinists and toolroom technicians are the primary installers of this collet type.

This collet is intended for use in manual lathes, CNC turning centers, and rotary indexers that accept the standard 5C collet format. It is well suited for production and job-shop applications where consistent workholding of round stock is required. The 5C collet system is widely used in both light and medium-duty machining of bar stock and turned components in job shops, toolrooms, and production cells.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before inserting or removing the collet, power down the spindle and confirm all motion has stopped. Threads should be inspected for debris or damage before seating the collet in the closer or chuck. Do not exceed the rated workpiece diameter, as overtightening or improper sizing can damage both the collet and the spindle nose.
