Description
The Bison 4306 series 4-jaw independent chuck in steel is a front-mount setup designed for machinists, fabricators, and hobbyists who need secure, flexible gripping on round and irregular workpieces. With four independently adjustable jaws, you can center and clamp complex shapes with precision, reducing setup time and rework.
This chuck ships with a set of solid reversible jaws and is manufactured in Poland, a heritage that underpins its reputation for durable construction and long tool life. Built to withstand demanding workshop use, it delivers dependable performance across a wide range of turning and milling applications.
- Independent four-jaw clamping for irregular shapes: Adjust each jaw separately to achieve precise centering and a secure grip on tricky workpieces, boosting accuracy and reducing rework.
- Solid reversible jaws included: Durable, flip-ready jaws provide versatile gripping profiles and extended jaw life, helping you adapt quickly to different parts without extra purchases.
- Front-mount, 400 mm capacity from Poland: Robust, rigid construction with a reliable mounting style and a large working diameter that supports stable, repeatable clamping in demanding tasks.
With this chuck, you gain faster, more confident setups, reliable holding power for large or oddly shaped parts, and a durable, long-lasting tool that stays consistent across jobs. Its independent jaw action and included jaws help you maintain steady workflow, improve cutting results, and reduce machine downtime.
