The Vortex 5C Imperial Lathe Collet – Round Bore, 1/8" – is a soft, bore-customizable collet designed for machinists who need a precise, tailor-made grip on small-diameter parts. Built for 5C lathe workholding, it lets you create a perfect fit by boring the collet itself to your exact size.

• Bore-customizable soft design: a soft collet intended to be bored to a specific size, depth, taper, or shape to match your component.
• Ultra-fine runout: delivers approximately 13–15 micron runout for tight concentricity on small parts.
• Re-boring capability: after initial boring, it can be bored again multiple times to accommodate larger parts; keep the pins for repeated use.
• 5C lathe compatibility: designed to fit standard 5C lathe collet chucks, a common setup in turning and precision machining.
• Size and bore: round bore at 1/8" for precise handling of small-diameter components.
• Pin-assisted opening: pins hold the collet open during the boring process for stable, accurate workholding.

Benefits: This collet lets you achieve a custom, centered grip on your unique part without committing to a fixed bore. The ability to re-bore extends the life of the tool for prototyping or small-batch production, reducing waste and downtime as you iterate on fits. With 5C compatibility and a precise 13–15 micron runout, it’s ideal for delicate shafts, bushings, sleeves, and other small components where a standard fixed-bore collet doesn’t provide the exact tolerance you need. For hobbyists and professionals alike, this approach offers flexibility, repeatability, and cleaner part finishes—minimizing runout-related scrapes and ensuring consistent performance across multiple parts.
