Vortex 5C Imperial Lathe Collet in Round Bore, 1/2" is a soft, borable collet designed for 5C lathe chucks. It’s built for machinists who need precise, customizable bore sizing that can evolve with their parts. Nominal bore: 1/2" round bore suitable for standard 5C lathe setups. Low runout: 13–15 micron runout for concentric turning and repeatable finishes. Soft bore design: Crafted to be bored to a specific size, depth, taper, or shape to match your component exact requirements. Open-position pins: Pins hold the collet open during the boring process, simplifying setup and improving accuracy. Re-boreable design: After initial boring, it can be re-bored multiple times to accommodate larger parts; retain pins for repeated use. Compatibility: Intended for use in a 5C lathe collet chuck, enabling precise, flexible machining workflows. This collet delivers precise, repeatable results in applications ranging from custom bushings and sleeves to pilot diameters for fixtures. Its re-boreable capability helps you adapt as project requirements change, reducing the need to stock multiple fixed-size collets. Ideal for shops and hobbyists who value accuracy, efficiency, and versatility in 5C lathe operations.
