8" 3-Jaw Lathe Chuck K11-200A, Self-Centering Hardened Steel Chuck High Precision with T-Key Mounting Bolts, 180mm Bolt Circle 65mm Center Hole for Metal Lathe Milling Drilling Machine
Description
- Versatile Clamping Range: This 8-inch (200mm) 3-jaw self-centering chuck offers a wide clamping capacity. The internal jaws clamp workpieces from 4mm to 85mm (0.16"-3.35"), ideal for precise small parts. The external jaws handle larger diameters from 65mm to 200mm (2.56"-7.87"). Whether you are machining shafts, discs, or hexagonal bars, this chuck provides secure holding for both internal and external turning operations
- High Precision & Low Runout: Model K11-200A features a high-precision scroll mechanism with an accuracy of ≤0.05mm (0.002"). The hardened steel jaws utilize a tongue-and-groove design for stable mounting, minimizing vibration during high-speed rotation. This ensures superior concentricity for your turning, facing, and drilling tasks, meeting the demands of economical CNC lathes and manual machining
- Heavy-Duty Hardened Steel: Constructed from high-quality precision-hardened steel, the chuck body and jaws offer exceptional wear resistance and durability. The L-shaped internal and external jaws are reversible and heat-treated to withstand high compressive forces, ensuring a longer service life compared to standard cast iron chucks. The silver finish resists corrosion, maintaining performance in demanding workshop environments
- Wide Compatibility & Easy Installation: Designed for general lathes, mini lathes, CNC lathes, milling machines, drilling machines, and grinding machines. Critical Mounting Specs: Bolt Circle Diameter (BCD) is 180mm (7.08") with 3-M10 mounting threads; Center Through-Hole Diameter is 65mm (2.56"). Please verify these dimensions against your machine's spindle adapter before purchase to ensure a perfect fit. Package includes mounting bolts for immediate setup
- Self-Centering Efficiency: The automatic self-centering mechanism allows for quick and accurate workpiece alignment without the need for individual jaw adjustments. Simply insert the workpiece and tighten using the included T-handle key. This significantly reduces setup time and eliminates repetitive calibration, boosting your overall machining efficiency and productivity
