For machinists who need a tailor-made bore, the Vortex 5C Imperial Lathe Collet – Round Bore, 1/4" delivers a precise, reworkable solution. This soft-bore collet is designed to be bored to your exact size, depth, taper, or shape, enabling custom components with consistent runout in a 5C lathe chuck. 13–15 Micron Runout: Achieves tight, repeatable concentricity once the bore is tailored to your specification. Soft Boring Collet: Intended to be bored to a precise diameter, depth, taper, or shape to perfectly match your component. Open-Bore with Pins: Pins keep the collet open during the boring process inside a 5C lathe collet chuck for clean, controlled boring. Re-Borability: After initial boring, the collet can be re-bored multiple times to accommodate larger parts; keep the pins for repeated use. Round Bore – 1/4": Specifically sized bore for a 1/4" workpiece, ideal for imperial (inch) applications. 5C Lathe Compatibility: Designed for standard 5C lathe collet chucks, a staple in machine shops and home workshops alike. With this 5C boring collet, you gain the flexibility to tailor bore dimensions to your exact workpiece, reducing setup time and improving accuracy across prototypes and small-batch runs. The ability to re-bore extends the tool’s life, letting you incrementally adjust diameter without purchasing additional collets. The open-bore design, stabilized by pins, supports a controlled boring process, helping you achieve repeatable results and better part fit from run to run.
