The 50 mm Independent 4-Jaw Lathe Chuck with M12x1.0 thread is a compact yet highly versatile and precision-engineered tool, specifically designed for small-scale lathes such as the Unimat DB and SL series, as well as other miniature or watchmaker-style lathes with compatible spindle threading. This independent jaw chuck is tailored to meet the demands of machinists, model engineers, hobbyists, and technicians who require both flexibility and precision in their workholding solution. Unlike self-centering chucks, this independent 4-jaw configuration offers full control over each individual jaw, enabling you to securely hold irregularly shaped, square, or off-center workpieces with exceptional accuracy. This makes it particularly suitable for fine machining operations that demand precise concentricity adjustments, such as eccentric turning, offset boring, and precision layout work. The independent adjustment also allows for clamping non-circular materials and asymmetric objects, giving the user unmatched versatility in a compact format. Manufactured from high-grade cast iron, the chuck body is built for long-term performance and is capable of withstanding the stresses and vibrations associated with continuous turning operations. Its robust construction provides excellent stability, rigidity, and vibration damping—critical factors for achieving smooth finishes and tight tolerances. The jaws are crafted from high-quality hardened and precision-ground tool steel, ensuring durability and reliable gripping power over extended use. The fine threading and smooth internal mechanisms allow for easy, controlled movement of the jaws, even under tight clamping conditions. The chuck's 50 mm diameter makes it perfectly proportioned for small workpieces and tight machine spaces, while the M12x1.0 threaded mount ensures a secure and direct fit onto Unimat spindles without the need for adapters or modifications. This straightforward installation process makes the chuck a practical upgrade for users seeking more advanced functionality than the standard self-centering 3-jaw chucks typically supplied with mini lathes. Its compact size also ensures minimal overhang from the spindle, which helps maintain spindle integrity and reduces runout. Whether you're turning metal, wood, plastic, or composite materials, this independent 4-jaw chuck provides unmatched clamping adaptability for miniature precision work. It's an ideal choice for miniature component manufacturing, watch part machining, prototyping, model engine building, and other fine-scale lathe applications where exact positioning and grip control are essential. Trusted for its robust performance and versatility, this Bluefox Tools 50 mm independent chuck is a staple for those who demand accuracy in a compact footprint. Whether you're upgrading your lathe setup or looking for a reliable secondary chuck, this tool delivers exceptional value and dependable performance for detailed and delicate workholding tasks.
