Description
The Bison 3864 series 6‑Jaw Steel Scroll Chuck is a robust, precision workholding solution for lathe operators who demand consistent grip and long service life. With a 250mm capacity and ground working surfaces, it provides even clamping to minimize damage and deflection while delivering reliable performance. Manufactured in the Bison Bial factory in Poland, these chucks are recognized for high quality and extended tool life.
Designed for a wide range of users—from engineers and machinists to hobbyists—the 6‑jaw configuration ensures a secure, uniform grip on round or irregular workpieces. This helps improve concentricity, reduces runout, and supports smoother turning and finishing tasks.
- 6‑jaw, uniform grip: Six jaws hold workpieces evenly for true concentricity and balanced turning, reducing wobble and improving finish quality.
- Ground working surfaces: Precision‑ground surfaces resist wear and maintain accurate jaw alignment, boosting durability and long‑term accuracy.
- Ready‑to‑use kit: Includes a wrench and 1 piece jaws with 1 set of reversible hard jaws and 1 set of outside hard jaws, enabling fast setup and versatile clamping for different parts.
This chuck helps streamline workflows by delivering repeatable gripping performance, minimizing setup time, and delivering consistent results across multiple jobs. Built for reliability and longevity, it’s a dependable choice for any workshop seeking durable, high‑quality tool holding.
