Value Collection 1230-4200 5C Round Collet 1.50 Mm

Product Description

The VALUE COLLECTION 1230-4200 is a 5C round collet machined from steel, designed to hold round workpieces in 5C-compatible spindles, chucks, and collet closers. With a collet size of 1.50 mm and a total indicated runout (TIR) of 0.015 mm, this collet provides consistent, repeatable workholding precision for 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. It is installed by machinists and toolroom technicians on manual lathes, CNC turning centers, and bench-top fixtures that accept the 5C collet standard.

This collet is suited for production and maintenance machining environments where close-tolerance workholding is required. Typical applications include holding small-diameter round bar stock, pins, shafts, and similar cylindrical parts for turning or secondary operations. The steel construction provides durability under repeated clamping cycles. At 0.5 pounds, the part is lightweight and easy to handle during tool changes.

Installation Notes

5C collets are installed and removed by machinists following standard lathe or collet-closer lockout and de-energization procedures. Ensure the spindle is fully stopped and the machine is locked out before inserting or removing the collet. Threads should be clean and free of chips before installation. Consult the machine tool manufacturer documentation for proper draw-tube torque and collet-closer adjustment procedures.
