Vortex 5C Metric Lathe collet - Round Bore - 8mm

The Vortex 5C Metric Lathe Collet – Round Bore – 8mm is a soft bore collet designed to be bored to a precise size, depth, taper, or shape to match your component. Specifically built for 5C lathe setups, it gives you a customizable bore that adapts to evolving parts without swapping multiple fixed-diameter pieces.

Pins are used to keep the collet open during the boring process, which is performed in a 5C lathe collet chuck. After boring, these collets can be re-bored multiple times to accommodate larger parts—so be sure to keep the pins for repeated use.

• Low runout for repeatable bore accuracy: With 13–15 micron runout, you get consistent bore alignment across setups, reducing scrap and improving part-to-part consistency.
• Boring-ready design with open-pin guidance: The pins hold the collet open during boring in a 5C lathe chuck, enabling clean, controlled shaping and easier rework when needed.
• Re-boreable and reusable for growing parts: Once bored, you can re-bore the collet to larger diameters, extending tool life and cutting costs by reusing a single collet across multiple projects.

This combination of adjustable sizing, reliable open-bore operation, and reusable design helps streamline setups, improve accuracy, and reduce downtime in small shop and production environments. The 8mm round bore provides a secure grip for small-to-medium workpieces, making it a practical choice for prototyping, fixture work, and repeatable production runs.
