Learn more about Klarna
Description
The Vortex 5C Imperial Lathe Collet — Round Bore, 9/16" is a precision, soft collet designed to be bored to a specific size for a perfect fit on your component. Built for use with a 5C lathe collet chuck, it enables a customizable bore that you can reuse across multiple jobs.

- Final bore diameter: Designed to be bored to 9/16" (0.5625") to match your precise component Requirements.
- 13–15 micron runout: Delivers tight concentricity for accurate turning and consistent results.
- Soft collet construction: Easy to machine and tailor to your exact size, depth, taper, or shape.
- Re-boreable design: Can be bored multiple times to accommodate larger parts; keep pins for repeated use.
- 5C lathe compatibility: Intended for use with standard 5C lathe collet chucks, integrating smoothly with existing setups.
- Open-bore setup with pins: Pins help keep the collet open during boring to maintain alignment and control.
This bore-customizable collet is ideal for machinists who need custom-fit components, such as bushings, sleeves, or precision inserts, without purchasing dedicated tooling for every size. Its re-boreable design minimizes downtime in prototyping and small-batch production while maintaining high precision and repeatability. Use it to create a tailored bore that ensures a secure, true hold on your part during turning, milling, or grinding operations.
