The Vortex 5C Round Bore Lathe Collet, 19 mm, is a soft, boreable 5C collet designed to be bored to your exact size, depth, taper, or shape. Used with a 5C lathe collet chuck, it lets you tailor the grip to each component while preserving accuracy for reliable machining.

This collet is ideal for engineers, machinists, hobbyists, and shops that frequently work with custom or prototype parts. Its 19 mm round bore is ready to be bored to your specification and reused across multiple jobs, helping you stay flexible without sacrificing performance.

• Custom bore-to-fit capability: Designed to be bored to a precise size, depth, taper, or shape to suit your component, with pins that keep the collet open during the boring process in a 5C lathe collet chuck. It can be re-bored multiple times to accommodate larger parts.
• Low runout for reliable gripping: Achieves 13–15 micron runout, helping maintain concentric holding and consistent machining results across passes.
• Reboreable and reusable design: Pins keep the bore open during boring, enabling repeated use and straightforward re-boring to expand part compatibility, reducing downtime and inventory needs.

By choosing this boreable Vortex 5C collet, you gain a flexible, precise gripping solution that adapts to changing part requirements. It supports accurate, repeatable results with fewer tool changes and allows you to extend the life of a single collet across diverse projects, improving workflow and overall productivity.
