Value Collection 1230-4232 5C Round Collet 17.50mm

Product Description

The VALUE COLLECTION 1230-4232 is a 5C round collet machined from steel, designed to hold round workpieces in 5C-compatible spindles, collet chucks, and collet closers. With a collet size of 17.50mm and a total indicator runout (TIR) of 0.015mm, this collet delivers the concentricity required for turning, milling, and grinding operations where workpiece accuracy matters. 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. Licensed machinists and toolroom technicians are the primary installers for this type of workholding component.

This 5C round collet is suited for use in manual and CNC lathes, rotary indexers, and spin fixtures equipped with a 5C collet system. It is appropriate for light to medium production work in job shops, toolrooms, and maintenance machine shops where repeatable workholding on round bar stock or turned parts is required. The 17.50mm bore size makes it a specific-size collet for that diameter of round stock or part shank.

Key Features

• 5C collet series — compatible with the widely adopted 5C spindle standard
• 17.50mm collet bore for precise grip on round workpieces of that diameter
• TIR of 0.015mm for consistent concentricity in turning and milling operations
• Steel construction provides durability under repeated clamping cycles
• Internal thread: 1.041 inches-24; External thread: 1.242 inches-20
• Lightweight at 0.5 pounds — easy handling during tool changes

Compatibility

Designed as an OEM-style replacement or standard addition for any machine tool equipped with a 5C collet spindle or collet closer accepting the standard 5C external thread specification.

Installation Notes

Installation and removal of 5C collets should be performed by a qualified machinist with the spindle or chuck fully stopped and the machine in a locked-out, de-energized state per OSHA lockout/tagout procedures. Use the appropriate collet wrench or spanner for the external thread to avoid damaging the collet body or threads. Inspect the collet bore and the spindle taper for chips or debris before seating the collet. Do not exceed the rated workpiece diameter for this collet, as overloading the bore will reduce clamping accuracy and can damage the collet.
