Description
The Bison 3204 series rear-mount, 3-jaw cast iron scroll chuck delivers solid, centered gripping for round workpieces with a 400mm capacity. This rugged chuck is built for consistent performance and is well suited to engineers, machinists, hobbyists, and workshop buyers who need reliable, repeatable results from their turning operations.
The chuck features ground working surfaces for true grip and longevity. It ships with a wrench and a complete jaw kit: one set of reversible hard jaws and one set of outside hard jaws, giving you flexibility to handle different stock profiles right away.
- Rear-mount 3-jaw design: Quick, centered grip on round stock with straightforward mounting for fast, repeatable setups.
- Cast iron construction with ground working surfaces: Delivers stiffness and precision over time, reducing runout and improving finish quality.
- Inclusive jaw kit and wrench: One set of reversible hard jaws and one set of outside hard jaws, plus a wrench, ready to tackle a variety of stock shapes without extra purchases.
With these capabilities, you can clamp parts quickly, maintain concentricity across turning operations, and reduce downtime by switching jaw styles as needed. The result is cleaner finishes, tighter tolerances, and greater confidence in every project.
