Description
The Bison 3274 series front-mount, 3‑jaw cast iron scroll chuck is designed for reliable gripping on lathes and turning equipment. With ground working surfaces, it delivers true concentric holding for round stock and cylinders, making it ideal for engineers, machinists, and hobbyists who value consistent performance and long tool life. This 630mm chuck can also be rear-mounted via an adapter plate, offering mounting flexibility across different machines.
Supplied with a wrench and two jaw sets—one set of reversible hard jaws and one set of outside hard jaws—this chuck is ready to handle a wide range of parts right out of the box.
- Precision-ground working surfaces: Ensures true concentric gripping and repeatable results, helping reduce setup time and part runout.
- Flexible mounting options: Front-mount design with optional rear mounting via adapter plate expands compatibility across different lathes.
- Ready-to-use jaw kit: Includes reversible hard jaws, outside hard jaws, and a wrench for immediate setup and versatile clamping across common workpiece shapes.
Built to endure tough workshop use, the chuck’s cast iron body and precision machining deliver durable performance and long tool life. The ground surfaces improve concentricity and reduce runout, while the rear-mount option adds mounting versatility to fit different machines. Paired with the included hardened jaws and wrench, it speeds up setup and delivers consistent clamping across a wide range of parts, from simple dowel work to precision turned components, helping you finish projects faster with confidence.
