Description
The Bison 3274 series front mount, 3 jaw cast iron scroll chuck offers robust, repeatable workholding for a wide range of turning and machining tasks. Designed for front mounting on compatible machines, it can also be rear-mounted using an adapter plate for added setup flexibility. With ground working surfaces, it delivers consistent grip and long-term accuracy across jobs.
The 400mm front-mount chuck is 100% manufactured in the Bison Bial factory in Poland, a name synonymous with durable build quality and long tool life. It ships with a wrench and a complete jaw package: one set of reversible hard jaws and one set of outside hard jaws, providing immediate versatility for roughing, finishing, and delicate workholding.
- Ground finished working surfaces: Precise, smooth gripping with reduced runout and longer service life, helping you rely on repeatable results across multiple parts.
- Front mount with rear-mount option: Flexible installation on your machine lineup, enabling quick changes between setups without swapping chucks.
- Complete jaw and wrench package: Ready-to-use right out of the box, including reversible hard jaws and outside hard jaws plus a wrench for fast changes and adaptable workholding.
This chuck is built for demanding shop environments, delivering stable performance, consistent clamping force, and extended durability. The combination of cast iron rigidity, precision-ground surfaces, and Polish manufacturing quality makes it a dependable choice for engineers, machinists, and hobbyists who value reliable results and efficient workflows.
