4-Inch Wood Lathe Chuck, 4-Jaw Self-Centering, 1x8 TPI

Wood lathe chuck delivers fast, centered holding for smoother woodturning with fewer re-adjustments. This 4-inch, 4-jaw self-centering chuck set fits common 1" x 8TPI spindles via included adapter, while the M33 x 3.5 internal thread supports wider lathe compatibility. High-hardness steel and a nickel-plated finish help resist shop moisture and dust, keeping clamping consistent for bowls, blanks, and irregular stock.

• Fits 1" x 8TPI lathes via included adapter; M33 x 3.5 internal thread expands compatibility.


• Delivers self-centering grip to reduce misalignment at speed and cut setup time.


• Locks inside clamp (1.5–2.8 in / 39–72 mm) for tenons and varied workpiece shapes.


• Supports outside grip (2–3.5 in / 50.5–89 mm) for secure holding on larger diameters.

Built for repeatable holding under cutting and carving loads, this 4-jaw chuck uses two locking bars for controlled jaw adjustment and steady tension. The corrosion-resistant nickel-plated surface helps reduce wear from damp shops and airborne dust, keeping the mechanism running smoothly over time. Whether you’re turning bowls, platters, or rough blanks, you get reliable centering and strong grip without constant tweaking. Grab yours today and keep your next turning project moving from mount-up to finish cuts faster.
