Feature

●Superior HT300 Material Our three-jaw chuck is made of HT300 material, 20Cr steel clamping jaw with 53HRC hardness and 40Cr steel auger with 45HRC hardness. The lathe chuck is hardened for high hardness and rust resistance, providing excellent work performance and reliability for both small and large workpieces.
●HIGH PRECISION A high-precision machining process ensures the structural stability and machining accuracy of the three-jaw chuck. The self-centering turning part includes a sensitive bevel gear and three pinions that contribute to precise machining progress. The storage tolerance is ≤0.05 mm.
●Inner & Outer Jaw The self-centering 3-jaw lathe chuck is equipped with an inner jaw and an outer jaw to expand the clamping range, and the outer jaws are able to clamp larger industrial parts. Clamping range:2-100mm You just need to turn it with the T-key and adjust it to the size and shape of your workpiece.
●EASY OPERATION The 3-jaw lathe chuck features a simple and compact structure that provides an optimal balance between function and reliability. The built-in self-centering function allows you to use it without repeated calibration. You only need to install it in the correct order and can use it with confidence.
●Applicable to Various Lathes Our self centering lathe chuck is highly adaptable to your usage requirements, whether you are working in metalworking, drilling or milling.

Description

100mm self centering triple jaw chuck

Features
Exceptional durability
The 3-jaw lathe chuck is made of high-strength HT300 material with high compressive strength and long service life. The jaw is made of 20Cr steel with a hardness of ≥ 53HRC and the auger is made of 40Cr steel with a hardness of ≥ 45HRC.
Excellent operating precision.
The 3-jaw chuck features a self-centering function and bevel gear to precisely control the accuracy of the clamped workpiece for accurate machining. Bearing tolerance ≤0.05mm ensures the structural stability and high accuracy of the lathe chuck.
Adjustable clamping jaw
We offer you two types of jaws, an inner jaw and an outer jaw suitable for clamping larger industrial parts. You can easily open and close the jaws by turning the T-shaped key.
Easy to use
This chuck consists of a chuck body, a movable chuck and a simple structure jaw drive. When clamping a workpiece, the chuck is able to automatically find and hold the center of the workpiece. All you need to do is install them in the correct order.
