Description

New Bison Self Centring Scroll Chuck 4 Jaw – Precision 4‑Jaw Workholding for Heavy‑Duty Turning

Take your lathe’s clamping capability to the next level with this heavy‑duty Bison self‑centring 4‑jaw scroll chuck, engineered to deliver reliable performance, exceptional grip, and quick setup for a wide range of turning applications. Designed for professional workshops and serious hobbyists alike, this chuck offers the versatility and robustness you need to tackle rectangular, square, or irregular components with confidence.

Key Features & Benefits

Self‑centring 4‑jaw design — Unlike independent 4‑jaw chucks, all four jaws move together on a scroll mechanism, providing faster part setup while still accommodating square or octagonal stock with consistent clamping pressure.
Solid construction with ground working surfaces — Precision‑finished contact areas ensure accurate clamping, smooth operation, and long service life under heavy machining conditions.
Supplied with reversible hard jaws and wrench — Ready to use straight from the box, with included hard‑faced jaws for both outside and inside gripping, plus a chuck key for fast jaw adjustments.
Rear/plain back mount with adapter compatibility — Fits a range of lathe spindles via rear mounting; many models can also be front mounted with an adapter plate (mounting options depend on configuration).
Ideal for 4‑sided and multi‑edge workpieces — Excellent choice for clamping square, rectangular, or polygonal stock that standard 3‑jaw chucks struggle with.
Balanced scroll plate for smoother rotation — Helps reduce vibration and allows stable performance at higher speeds in appropriate applications.

Built to Bison’s high standards in Poland, this 4‑jaw scroll chuck gives you the performance and durability expected from a professional‑grade workholding accessory — perfect for turning tasks that require secure grip and efficient setup.
