High-quality material: Diameter: 5 inches/125 mm. The body of the 4-jaw mini lathe chuck is made of cast iron that has passed rigorous quality tests. It features high strength and toughness, compressive strength, durability, and a long service life.
Reversible jaw set: The chuck is equipped with three inwardly offset jaws that can be moved inwards or outwards to hold raw materials of different shapes. The high-precision design of the chuck's bevel gear ensures accurate chuck operation.
Improved flexibility: The T-shaped clamping wrench of the rotating part allows for the installation of various workpieces. And the effortless operation reduces changeover time for your convenience. Internal jaw clamping range: 0.276"-2.244" / 7-57 mm. External jaw clamping range: 1.89"-4.92" / 48-125 mm.
High precision: The 4-jaw chuck operates with precision, and the bearing tolerance is ≤ 0.003 inches / 0.07 mm to ensure satisfactory metalworking. The included accessories make the spiral chuck highly adaptable and compatible with the same jaw series as the collet chuck.
Remarkable versatility: This independent 4-jaw metal chuck has a compact design. It is suitable for installation on many types of metal chucks and for clamping workpieces of various shapes.

If there had also been technical drawings, it would have been much easier to build the flange connector on the lathe.

Everything is fine. The only clarification that should be made is the position of the rear holes, which is not mentioned in the description. It has 4 spaced 90 degrees apart from each other. Probably suitable for most supports except for mine. They would provide an excellent service if they included the technical specifications of the items.

Excellent product. As described. It takes a little while to center it, as I'm used to auto-centering. But once you get the hang of it, it's a pleasure to use.

I don't understand why, in the catalog, the same 125mm spindle in various configurations has a rear attachment with 3 screws and 4 screws, but in the details of the content, it is indicated as 3 screws for all (K11-125 K12-125 K72-125). I received a spindle with a 4-screw attachment.
