Lathe Chuck 50 mm Self-Centering 3-Jaw Mounting Unimat Thread M12x1.0 | Jaws Hardened & Ground | Material Tool Steel | Bluefox Tools Threaded Chuck

The 50 mm Self-Centering 3-Jaw Lathe Chuck with M12x1.0 thread is a compact, precision-machined workholding accessory engineered for Unimat mini lathes and other small bench-top machines using the same spindle mount. Designed to deliver quick, repeatable, and concentric clamping, this chuck is an essential tool for users seeking ease of operation, high accuracy, and dependable performance in small-scale turning applications.

Unlike independent jaw chucks, the self-centering 3-jaw mechanism simultaneously moves all jaws together—automatically aligning round or hexagonal workpieces to the spindle centerline with minimal effort. This feature makes it ideal for cylindrical parts, shafts, and repeat operations where fast setup and precise concentricity are required.

The chuck body is constructed from high-strength cast iron for excellent rigidity and resistance to vibration, while the jaws are crafted from hardened and ground steel for maximum durability and wear resistance. The internal scroll mechanism is precision-machined to ensure smooth and uniform jaw movement, providing consistent gripping power and high concentricity—often within tight tolerances suitable for fine machining.

With a compact 50 mm outer diameter, this chuck is perfectly suited for micro-machining, jewelry work, small model components, and prototyping tasks. The M12x1.0 threaded back allows it to be directly mounted onto Unimat DB/SL lathes without requiring additional adapters or mounting hardware, ensuring a secure and efficient setup.

Whether you’re turning brass, aluminum, steel, plastic, or wood, this self-centering 3-jaw chuck offers the reliability, ease of use, and precision needed for professional results in a small-format lathe environment. Its simplicity, speed of operation, and solid build quality make it a favorite among hobbyists, toolmakers, and precision engineers alike.
