Why Shop Pre-Owned?

When the job requires uncompromising stability, there is no substitute for the Magna Lock USA name. Since 1948, MLUSA has set the industry benchmark for electromagnetic workholding. We don’t just build chucks; we build industrial-grade foundations designed to outlast the machines they sit on.

Our collection of Pre-Owned and Remanufactured Chucks gives you access to that legendary holding power at a price point that respects your bottom line. These aren't "used" tools—they are proven assets, over-engineered for a lifetime of service, completely rebuilt from the ground up to meet current OEM standards.
