Value Collection 1230-4242 5C Round Collet 22.50mm

Product Description

The VALUE COLLECTION 1230-4242 is a 5C round collet machined from steel, designed for use in 5C-compatible spindles, collet chucks, and indexing fixtures found in turning, grinding, and milling operations. With a collet size of 22.50mm and a Total Indicator Runout (TIR) of 0.015mm, this collet delivers the concentricity required for precision workholding on production and tool-room equipment. 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 tool-room technicians install this collet as a direct workholding component when close-tolerance gripping of round stock is required.

This 5C round collet is suited for use on lathes, grinders, screw machines, and manual or CNC turning centers equipped with a standard 5C spindle. It accepts round workpieces at its rated 22.50mm grip size and is appropriate for both production-run environments and job-shop setups. Steel construction provides the rigidity and wear resistance expected in repetitive workholding applications. No specific model compatibility data was provided by the manufacturer for this part.

Installation Notes

5C collets are installed by qualified machinists or tool-room technicians. Before installing or removing a collet, ensure the machine spindle is fully stopped and the machine is locked out per applicable safety procedures. Use the appropriate collet closer or draw tube for your spindle; never force the collet into the spindle bore with impact tools. Inspect the collet bore and spindle taper for burrs or debris before seating to protect TIR performance.
