Description
The Bison 3704 series rear mount, 4 jaw steel scroll chuck (400mm) is built for demanding machining tasks where precise, repeatable gripping matters. It features a balanced scroll plate and hardened, ground working surfaces to deliver reliable clamping and long tool life. All Bison scroll chucks are 100% made in the Bison Bial factory in Poland, a testament to quality and durability you can trust in daily use.
- Balanced scroll plate for consistent gripping: Provides even clamping force across all jaws, reducing runout and delivering repeatable, accurate results.
- Hardened and ground working surfaces: maximizes wear resistance and precision over countless cycles, helping maintain accuracy over time.
- Complete with wrench and 1-piece jaws: Includes 1 set of reversible hard jaws and 1 set of outside hard jaws, so you’re ready to tackle a range of workpieces right away.
This chuck delivers reliable, repeatable holding that speeds setup and minimizes downtime. Its robust construction and precision-ground surfaces translate to cleaner finishes and fewer part slippages, while the Polish manufacturing heritage provides confidence in long-term performance for workshops, job shops, and training environments alike.
