The Bison 315mm steel scroll chuck is a rugged 3‑jaw workholding solution designed for turning cylindrical parts with confidence. It supports both front‑mount operation and rear‑mount installation via an adapter plate, making it versatile for a wide range of lathes.

Manufactured in Poland at the Bison Bial factory, this chuck features a balanced scroll plate and hardened, ground working surfaces to deliver long tool life and consistent gripping force across jobs.

• Balanced scroll plate: Ensures smooth, true rotation with reduced runout and vibration for better cut quality and finish.
• Hardened and ground surfaces with 2-piece jaw set: Provides durable, repeatable clamping with two jaw styles—hard top jaws and hard master jaws—so you can quickly switch between common part shapes without sacrificing grip or precision.
• Rear mounting option with adapter plate: Adds mounting flexibility to adapt to machines designed for rear mounting, while remaining fully compatible with front‑mount setups.

With the Bison 315mm 3‑jaw scroll chuck, you gain dependable, repeatable performance across a wide range of turning tasks. The balanced scroll reduces chatter, the hardened surfaces and included jaw set boost durability and versatility, and the rear‑mount option expands machine compatibility to minimize downtime during setup changes. Built in Poland to exacting standards, this chuck delivers reliable, long‑lasting performance that helps you finish parts faster and with greater confidence.
