About this item
Quench-Hardened Jaws (≥53 HRC) for Outstanding Durability and Hardness
This lathe chuck is constructed from high-quality HT300 cast iron, a material renowned for its high tensile strength and excellent vibration-damping properties. To ensure longer life under harsh conditions, critical components have been subjected to a special hardening and tempering process. The 20Cr steel jaws reach a hardness of ≥53 HRC, while the 40Cr steel sliding plate reaches ≥45 HRC, ensuring outstanding wear resistance, to deformation and abrasion resulting from years of intense use.
This superior hardness ensures that the chuck jaws maintain their precise gripping edges and that the internal sliding mechanism operates smoothly, without premature wear. The heat treatment process also improves the product's overall resistance to rust, protecting it from corrosion in a typical shop environment. This is a professional-grade tool, designed to withstand the rigors of both amateur and professional mechanical work, providing a reliable foundation for all your projects.
8-Inch 3 Jaw Lathe Chuck with a 2 1/4 in-8 Backing Plate
This 8-inch chuck offers a through-hole inside diameter of 2.56 inches (65 mm) and an outside diameter of 8 inches (200 mm), making it suitable for a wide range of lathe sizes. It includes a backing plate with a 2 1/4 in-8 pre-threaded adapter, allowing for a quicker, more stable, and secure connection to the machine chuck. This eliminates the need to source or make a separate adapter, simplifying the setup process.
The chuck offers a wide clamping range from 0.16 inches up to 7.87 inches (4 to 200 mm), making it incredibly versatile. It features two sets of jaws, one internal and one external, which allow it to firmly grip both solid and hollow pieces of various sizes. This versatility allows you to tackle a wide range of projects without having to change spindles.
Simplified Structure 3 Jaw Lathe Chuck for Hassle-Free Operation and Installation
Designed with a simple, compact, and reliable structure, this 3 Jaw Lathe Chuck is straightforward to install and use. The package includes a T-handle chuck wrench, which is the only tool needed to tighten and expand the jaws, making workpiece changes quick and effortless. Thanks to the simple installation procedure, you can mount the chuck and start working in just a few minutes.
Operation is intuitive; turn the key counterclockwise to expand the jaws and clockwise to tighten them on the workpiece. While some users may note that the chuck feels a little stiff initially, this is normal for new, precision-machined tools. Quick disassembly for cleaning and lubrication will ensure smooth and precise operation, as confirmed by satisfied customers.
High-Precision Self-Centering Function for Flawless Performance
The VEVOR 3 Jaw Lathe has a built-in self-centering feature that automatically places the workpiece at the exact center with a simple turn of the wrench. This key feature removes the need for tedious and repeated manual calibrations and adjustments, saving you time and effort when setting up each project. This tool is ideal for efficiently clamping round or hexagonal workpieces with consistent precision.
This chuck is designed for exceptional accuracy, a fact confirmed by past, satisfied users who report the incredibly low runout values. Measurements are down to 0.002” and 0.001", and even a deviation of just 0.01mm right out of the box.
Versatile 0.16"-7.87" Clamping Range for Diverse Workpieces
This 8-inch chuck offers a vast total clamping range, from 0.16 inches to 7.87 inches (4 to 200 mm), making it one of the most versatile tools in the shop. This range is made possible by the inclusion of two distinct sets of jaws. The internal jaws (A-A1) are used to grip the outside diameter of smaller workpieces, while the outer jaws (C-C1) are inverted to grip the inside of hollow pieces or the outside of larger pieces.
This comprehensive range allows you to handle a vast variety of applications with a single chuck. You can hold pins and small rods securely and then quickly change jaws to work on large rings, discs, or pipes. The ability to clamp such a wide range of workpiece sizes makes this 3-jaw lathe chuck a true workhorse. It offers the flexibility to tackle almost any turning project that comes into your shop, making it a valuable and widely used tool.
