Description
The Bison 4306 series Steel 4-Jaw Independent Chuck (315mm) is a front-mount workholding solution built for precision and versatility. Designed for machinists, engineers, and hobbyists who frequently clamp irregular shapes, this chuck lets you set each jaw independently to center and secure odd contours with confidence.
Made in Poland, Bison chucks are recognized for durable construction, long tool life, and reliable performance. This model ships with one set of solid reversible jaws, delivering immediate versatility for a wide range of workpieces.
- Independent jaw adjustment for irregular shapes: Each jaw can be positioned separately, enabling precise centering and firm, customizable gripping on irregular or multi-diameter parts.
- Solid reversible jaws included: One set of durable jaws provides versatile, long-lasting gripping that can be swapped to suit different materials and part profiles without extra accessories.
- Front-mount design for fast setup: Easy installation and alignment from the front, reducing setup time and delivering repeatable clamping performance across multiple parts.
This chuck helps you streamline workflows by delivering reliable, repeatable grip on challenging parts, minimizing runout, and reducing downtime between setups. With Polish-made quality and a proven tool-life reputation, you can count on consistent performance across your turning or milling projects, whether you’re a professional shop, a maker space, or a dedicated garage engineer.
