Precision-ready and customizable, the Vortex 5C Imperial Lathe Collet — Round Bore, 3/8" — is designed for machinists who need a bespoke bore size tailored to their component. This soft collet is built to be bored to meet exact specs and then reused as your part designs evolve. Bore diameter: Round bore of 3/8" to match your component and tooling setup. Low runout: Engineered to deliver 13–15 micron runout for precise turning and consistent part quality. Soft, borable material: Designed to be bored to a specific size, depth, taper, or shape to fit your exact component geometry. Reborable design: After initial boring, can be re-bored multiple times to accommodate larger parts; keep the pins for repeated use. 5C lathe compatibility: Used with a standard 5C lathe collet chuck for secure, reliable holding during machining. With this collet, you gain the flexibility to tailor holds for unique parts, streamline setups for small runs, and maintain tight tolerances without sacrificing efficiency. The ability to bore to a precise dimension and re-bore as your project grows helps reduce changeovers and improve consistency across batches—making it an essential tool for custom fabrication, prototyping, and precision turning on 5C lathes.
