Bison Cast iron Scroll Chucks - 3 Jaws - 1 piece Jaw (Front Mount) - 125mm

The Bison 3274 series 125mm front-mount, 3-jaw cast iron scroll chuck is built to deliver steady, precise grip on round stock in a wide range of lathes. With ground working surfaces and durable construction, it’s ideal for engineers, machinists, hobbyists, and workshop teams seeking reliable, long-lasting performance in everyday turning tasks.

This model offers flexible installation: it’s a front-mount chuck by default but can be rear-mounted using a dedicated adapter plate to fit non-standard spindles. It’s shipped with a wrench and a complete jaw package, including reversible hard jaws and outside hard jaws, so you’re ready to tackle a variety of parts from day one.

• Ground working surfaces for true running: Precision-ground contact faces on the jaw mating surfaces ensure accurate gripping and repeatable results even during demanding turning tasks.
• Flexible mounting options: Front-mount design for straightforward setups, plus rear-mount capability via an adapter plate to fit different machines and configurations.
• Ready-to-use jaw kit with wrench: Includes reversible hard jaws and outside hard jaws along with a wrench, enabling fast, versatile setups without needing additional purchases.

Built in Poland at the Bison Bial facility, this chuck embodies the brand’s commitment to quality and tool life. The cast iron body provides rigidity and durability under heavy use, while the ground surfaces maintain stable grip for consistent results. The combination of a straightforward front-mount workflow and optional rear-mount adaptability reduces downtime and speeds up setup, delivering reliable performance across a broad range of jobs.
