Vortex 5C Imperial Lathe collet - Round Bore - 11/16"

The Vortex 5C Imperial Lathe Collet with Round Bore at 11/16" is a soft, boreable collet designed for machinists who need a precise, custom bore that can be sized to fit a specific component. It works with a 5C lathe collet chuck to deliver a flexible, repeatable solution for evolving part tolerances.

• Bore size: Round bore of 11/16" that is intended to be bored to your exact final diameter
• Soft collet design: Made to be bored and re-bored to match your component’s size, depth, taper, or shape
• Precision runout: 13–15 micron runout to support accurate turning and concentricity
• Re-borability: Can be bored multiple times to accommodate larger parts, with pins used to keep the collet open during the process
• Pin-assisted opening: Pins hold the collet open during boring for consistent sizing and easier setup
• 5C compatibility: Designed for use in a 5C lathe collet chuck, a common standard in small to mid-scale machining

Designed for flexibility in the workshop, this Vortex 5C round-bore collet is ideal for prototyping, custom bushings and sleeves, or small-batch production where a precisely sized bore matters. The ability to bore and re-bore ensures you can adapt to new part geometries without purchasing additional fixed-diameter collets, while maintaining tight tolerances and reliable concentricity. It’s a practical solution for shops that value accuracy, repeatability, and workflow efficiency.
