Value Collection 230-4217 5C Round Collet 17mm

Product Description

The VALUE COLLECTION 230-4217 is a 5C round collet machined from steel for use in 5C-compatible spindles and collet closers found on lathes, indexers, and rotary fixtures. The collet accepts workpieces at a 17 mm collet size and holds a total indicator reading (TIR) of 0.015 mm, supporting consistent concentricity across turning and grinding operations. The internal thread measures 1.041 inches-24 and the external thread measures 1.242 inches-20, both standard dimensions for 5C tooling. Machinists and tool-room technicians install this collet as part of standard workholding setups on manual and CNC lathes.

This 5C round collet is suited for machine shops, tool rooms, and production environments requiring reliable workholding for round-stock applications. It fits standard 5C spindle noses and collet closers used across a wide range of metalworking lathes and indexing fixtures. The steel construction makes it appropriate for everyday turning, facing, and light grinding of bar stock and round workpieces in both job-shop and production settings.

Installation Notes

Installation should be performed by a qualified machinist with the spindle fully stopped and the machine locked out per shop safety procedures. Inspect the collet bore, taper, and threads for chips or burrs before seating in the collet closer. Do not force the collet into the spindle; hand-thread until snug before engaging the closer. Clean all mating surfaces to maintain the specified TIR.
