The Vortex 5C Metric Lathe Collet – Round Bore – 26mm is a soft bore collet designed to be bored to a precise size, depth, taper, or shape to match your component. Used in a 5C lathe collet chuck, it provides a flexible, reliable way to hold non-standard parts with confidence. Pins are used to keep the collet open during the boring process, which is performed in a 5C lathe collet chuck. Once bored, these collets can be re-bored multiple times to accommodate larger parts—so be sure to keep the pins for repeated use. Customizable bore size: Soft collets designed to be bored to a specific size, depth, taper, or shape to suit your component. Low runout for precise results: 13–15 micron runout ensures tight, repeatable holding and consistent part quality. Re-bor-able with reusable pins: After boring, reuse these collets for larger parts and keep pins for repeated use to minimize downtime. With the Vortex 5C Round Bore collet, you gain a versatile, repeatable holding solution that adapts to your parts, streamlines setups, and supports consistent, high-quality results across jobs. This approach—custom bore, tight runout, and reusable pins—helps you complete projects faster and with dependable accuracy.
