Description
The Bison 4304 series Cast Iron 4-Jaw Independent Chuck is a front-mount lathe chuck designed to freely grip irregular and non-round workpieces with precision. With four independently movable jaws, you can true and clamp complex shapes for secure, concentric results. It ships with one set of solid reversible jaws, ready to use on your 400 mm chuck.
- Independent jaw adjustment for irregular shapes: Move each jaw separately to center and grip oddly shaped parts, delivering improved runout control and a tighter, more dependable hold.
- Front-mount design with a single solid reversible jaw set: Simplifies setup and delivers reliable clamping across a range of part sizes without complex jaw configurations.
- Durable cast-iron construction: Built for rigidity and long tool life, delivering consistent performance in daily machining and reducing downtime.
Manufactured in Poland, the Bison chuck combines sturdy construction with proven reliability to support demanding workshop use. Its 400 mm size provides a balance of capacity and stiffness, making it well-suited for a broad spectrum of turning tasks—from routine parts to challenging, non-standard workpieces. Trust in its robust build and independent jaw control to deliver repeatable, professional results.
