Description
The Bison 4304 series Cast Iron 4 Jaw Independent Chuck (Front Mount, 200mm) is a flexible workholding solution for turning and milling setups. Supplied with 1 set of solid reversable jaws, each jaw can be positioned independently to clamp irregular shapes with precision and control.
Manufactured in Poland, Bison chucks are renowned for exceptional quality and long tool life, delivering dependable performance in demanding workshop environments.
- Independent jaw positioning for irregular workpieces: Each jaw can be moved separately, allowing precise gripping of off-center or irregular profiles for stable, repeatable clamping.
- Solid reversable jaws included: One set of solid reversable jaws provides immediate versatility and can be flipped for different grip configurations, saving setup time.
- Durable cast-iron body, front-mount design: Built for rigidity and long service life; the front-mount arrangement simplifies installation on compatible machines and supports consistent results.
By enabling independent jaw control, you can clamp irregular workpieces with confidence, reduce time spent on setup, and achieve stable, repeatable gripping across different shapes. The included solid reversable jaws add versatility from the start, while the rugged cast iron body and Poland-made manufacturing heritage ensure lasting performance and dependable results in busy workshops.
