The Vortex 5C Metric Lathe Collet – Square – 12mm is an emergency 5C collet designed to adapt quickly to unique components in 5C lathe setups. Its soft construction allows the bore to be machined to precisely match your part’s size, depth, taper, or shape, making it ideal for prototypes, fixtures, and bespoke machining tasks.

Fitted pins keep the collet open during the boring operation in a 5C lathe collet chuck, providing clean, controlled adjustment and safer, smoother machining. Best of all, this emergency collet can be re-bored many times to accommodate larger parts, extending its useful life and reducing the need for new collets on evolving project demands.

• Low runout for reliable accuracy: Delivers 13–15 micron runout, helping you maintain concentricity and achieve consistent finishes across passes.
• Customizable bore for a perfect fit: The soft collet can be bored to the exact size, depth, taper, or shape needed for your component, with pins keeping it open during setup for precise boring.
• Re-boreable and reusable design: Re-bored many times to hold larger parts as your projects evolve, reducing waste and extending tool life; pins can be retained for continued use.

This collet helps streamline workflows by letting you tailor your gripping solution on the fly, minimizing tool changes and improving part quality. With 5C compatibility, square geometry, and a 12mm size, it’s a practical, durable choice for engineers, machinists, and hobbyists who demand flexibility without sacrificing reliability.
