The heavy-duty Oneway Stronghold Chuck is designed for large lathes (16" swing or greater) to provide maximum gripping power. The large body diameter and heavy weight make it especially desirable on medium to large sized lathes.

Oneway Chucks are equipped with Oneway's patented profile top jaw shape. This shape increases gripping power at all diameters of round and square stock. Less wood damage also occurs with this jaw shape than with conventional round-shaped jaws.

Why the Stronghold Chuck is Superior

• Base jaws are made from carbon steel. Precision grinding on the sides provides for the exact and controlled clearances which are required for wood turning chucks.
• Base jaws are case hardened which makes them longer lasting, stronger, and non-seizing in use.
• Scroll is precision machined and case hardened. The bore is honed to exact tolerances after heat treating.
• The scroll is manganese phosphate plated which acts as an anti-seize compound. Less lubrication is consequently required for smooth running action over the life of the chuck.
• The body is precision machined. Electroless nickel plating provides a hard wearing surface for base jaws and scroll while giving the added bonus of providing excellent corrosion resistance.
