Vortex 5C Imperial Lathe Collet – Hex 5/16" is an emergency collet designed for 5C lathe chucks, engineered to accept custom boring operations with tight tolerances. It’s ideal for machinists who need quick, adaptable tooling for bespoke components.

• Size / Fit: Hex 5/16" — compatible with standard 5C lathe collet chucks for reliable clamping.
• Runout: 13–15 micron runout for precise boring and consistent workpiece features.
• Emergency Collet Design: Soft construction that can be bored to size, depth, taper, or shape to match a specific component.
• Open Position Pins: Pins keep the collet open during boring operations, simplifying setup in a 5C lathe.
• Re-borability: Re-bore many times to hold larger parts as your projects evolve; reuse the pins instead of discarding them.

Use cases include creating a custom holding solution for irregular shafts, tailoring the collet to unusual lengths, or achieving project-specific tolerances in fabrication, repair, and prototyping environments. This approach minimizes setup changes and helps maintain accuracy across a sequence of part runs.
