Material: The 3-jaw lathe chuck is made from HT300 material, with 20Cr steel chuck jaws that have a hardness of 53HRC and a 40Cr steel cylinder with a hardness of 45HRC. The chuck is treated for superior hardness and rust resistance, providing excellent work performance and reliability for various workpieces.

High Precision: The high-precision machining process ensures the stability and accuracy of the 3-jaw chuck's machining. It includes fine conical gears and three pinion gears for precise machining progress. The bearing tolerance is ≤0.05 mm.

Dual-Jaw Use: The chuck jaws can be used as both internal and external jaws, ideal for securing larger industrial parts. The clamping range is 0.16-8 in / 4-200 mm.

Easy Operation: It features a simple structure with an integrated self-centering function, allowing for easy use without repeated calibration.

Applications: Ideal for metalworking, drilling, and milling, it enhances machining efficiency and offers precise and consistent results.
