What makes the stronghold a superior chuck?

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

Add these quality materials and precision manufacturing to features such as:

• 4-Jaw scroll chuck
• Profiled top jaws
• Patented safety feature allowing maximum travel
• Key operation allowing one handed tightening and solid holding power
• Superior taperlock adaptor
• And its one-of-a-kind woodworm screw
• Equals an absolutely superior chuck!

Note: If your lathe has less than a 16" swing, the Oneway Talon Chuck (20761) is recommended. Stronghold Chuck jaws are NOT compatible with either the original Oneway Chuck or the Talon Chuck.
