Value Collection 1230-4241 5C Round Collet 22mm

Product Description

The VALUE COLLECTION 1230-4241 is a 5C round collet machined from steel, designed to hold round workpieces in lathes, collet chucks, and collet closers that accept the 5C collet standard. The collet measures 22.00 mm in collet size and holds a total indicated runout (TIR) of 0.015 mm, making it suited for work that demands consistent concentricity. The internal thread measures 1.041 inches at 24 threads per inch, and the external thread is 1.242 inches at 20 threads per inch. Machinists, toolroom operators, and CNC lathe technicians are the primary installers. The part weighs 0.5 pounds.

This 5C round collet is used in manual engine lathes, CNC turning centers, indexers, and spin fixtures equipped with a 5C spindle nose. It is a standard fitment for production turning, secondary operations, and toolroom work where repeatable workholding on round bar stock or round-shank tooling is required. The 5C collet system is common in both job-shop and production environments handling small to medium diameter round stock.

Installation Notes

Installation is performed by machinists or toolroom personnel. Before installing or removing the collet, ensure the machine spindle is fully stopped and the power is locked out per shop lockout/tagout procedures. Threads should be clean and free of chips or burrs before seating the collet into the closer or chuck. Do not exceed the rated collet size by attempting to force oversize stock, as this can damage the collet and spindle threads.
