Vortex 5C Metric Lathe collet - Round Bore - 12mm

The Vortex 5C Metric Lathe Collet — Round Bore, 12mm — is a soft 5C boring collet designed to be bored to a precise size, depth, taper, or shape to fit your component. Used with a 5C lathe collet chuck, it enables you to tailor the bore for a snug, repeatable grip on your part.

Designed for engineers, machinists, hobbyists, and workshop teams, this collet offers flexible setup and long-term usability. Pins help keep the collet open during the boring process, supporting accurate preparation that you can rework as your projects evolve.

• Low runout for precision: Delivers 13–15 micron runout to maintain concentric bore accuracy, helping parts fit true and reducing finishing or rework.
• Re-boreable for long-term flexibility: Bored to a specific size, depth, or taper and then re-bored as needed to accommodate larger parts, maximizing reuse and reducing tooling costs.
• Pin-assisted opening for reliable setup: Pins keep the collet open during boring in a 5C lathe chuck, enabling stable setups and quick reuses for multiple jobs.

This collet provides a versatile, cost-effective solution for custom components. By enabling precise, repeatable bore preparation and easy re-boring, it helps streamline workflows, shorten setup times, and deliver consistent results across a range of parts and applications.
