Bison Cast iron Scroll Chucks - 3 Jaws - 1 piece Jaw (Front Mount) - 250mm

The Bison 3274 series front-mount, 3-jaw cast iron scroll chuck is engineered for reliable, repeatable grip on round workpieces. With a 250 mm diameter and ground working surfaces, it delivers true concentric holding for a wide range of turning tasks, from precise finishing to heavy-duty machining. The design also supports rear mounting via an adapter plate, giving you flexible integration with different lathes without swapping chucks.

• Front‑mount 3‑jaw design with ground surfaces: Delivers solid, repeatable grip with reduced runout, helping you achieve accurate, consistent part concentricity across multiple setups.
• Rear-mount compatibility with adapter plate: Expands versatility by allowing a quick switch to back‑mount configuration on compatible machines, preserving performance without buying a new chuck.
• Complete jaw set and included tools: Includes a wrench and one set of reversible hard jaws plus one set of outside hard jaws, enabling fast, tool‑ready changes for different workpieces and reducing downtime.

The Bison name stands for durable construction and long service life. All chucks in this line are manufactured in the Bison Bial factory in Poland, delivering dependable quality you can trust on demanding production runs or detailed hobby projects alike. This combination of robust build, precise ground surfaces, and flexible mounting makes it a reliable centerpiece for achieving first-pass accuracy and smooth workflow.
