*KeyFeatures *High-Strength #45 Material: To meet the demanding requirements of production environments, we utilize #45 material that has undergone quenching and hardening techniques. This imparts exceptional hardness and rust-resistant properties, ensuring outstanding performance and reliability for both small and large workpieces held by the chuck. *High Precision: In the manufacturing of our chucks, we employ high-precision machining processes to ensure structural stability and machining accuracy. The lathe components feature a refined bevel gear and three small gears, aiding in precise machining progress. Bearing tolerance is 0.3 mm / 0.01 inch, guaranteeing excellent machining results. *Versatile Single Jaw: Our chuck features an adjustable jaw design, providing enhanced flexibility. Operators can easily adjust the clamping range using a T-handle wrench, accommodating workpiece sizes and shapes such as bowls, plates, vases, cups, and more with precise gripping and securing. *Simple & User-Friendly: The chuck boasts a streamlined design, striking the optimal balance between functionality and reliability. By eliminating unnecessary complex components and mechanical structures, the chuck's design becomes simple and compact. Installation and removal only require screws and handles, and clamping and spreading are achieved by rotating the T-handle wrench. *Wide Range of Applications: Whether you're involved in woodworking, drilling, grinding, or other fields, the chuck's broad adaptability meets your requirements. By using our lathe chuck, you can enhance processing efficiency, increase operational flexibility, and achieve accurate and stable machining outcomes. Whether for personal use or industrial production, this lathe chuck delivers outstanding performance and reliability to cater to your needs. ******************************************************************************************************* *Specifications Model: KP2-3/4 Chuck Outer Diameter: 2.75 inches / 70 mm Clamping Range (Inner): 1.18-1.85 inches (30-47 mm) Chuck Internal Thread: 1*8TPI Support Range (Outer): 1.5-2.24 inches (38-56 mm) Outer Diameter Runout: 0.15 mm Test Bar Radial Runout: 0.40 mm at a distance of 50 mm Test Ring End Face Runout: 0.15 mm Surface Treatment and Color: Ra1.6, chrome-plated natural color Main Material: 45# Net Weight: 3.2 pounds / 1.47 kg Product Dimensions: 70 x 65 mm ******************************************************************************************************* *Pakcage Content 1 x T-Wrench 1 x Cone Screw 1 x T-Handle Wrench 1 x M33*3.5 Adapter 1 x Instruction Manual
