Chuck for wood lathe 100mm M33x3.5

Fits wood lathes with 1" x 8 TPI thread: This 4-jaw chuck has a 4" (approx. 100mm) outer diameter and an M33 x 3.5mm inner thread. The included 1" x 8 TPI adapter fits the corresponding machine spindles exactly, making this chuck ideal for most medium to large wood lathes.
Expansion and compression: The 4 jaws are adjustable using two locking rods. With a 39-72mm expansion (internal) and 50.5-89mm compression (external) range, this chuck securely holds workpieces of various shapes.
Self-centering design with bevel gear: Our self-centering chuck automatically keeps the workpiece centered even at high rotation speeds. This reduces centering errors without the need for manual adjustment, effectively increasing machining efficiency.
Wood screw clamping: The chuck is equipped with a tapered wood screw for clamping large, flat workpieces. You can quickly clamp the workpiece by drilling a 1-inch (approx. 25 mm) deep and 0.3-inch (approx. 7.6 mm) diameter hole in its center.
Strong and durable: Made of high-strength steel and coated with a corrosion-resistant nickel layer, this woodworking chuck is reliably protected from moisture and dust. It remains stable even during long-term cutting and carving work.
