3-jaw lathe chuck, 5'', self-centering lathe chuck, 0.1-5 inch/2.5 -125 mm clamping range with T-key fastening screws Reversible jaws, for lathe 3D printer processing Center milling drilling machine

Superior HT300 Material: Our 3-jaw lathe chuck is constructed of HT300 material, 20Cr steel chuck back with 53HRC hardness and 40Cr steel scroll with 45HRC hardness. The lathe chuck is case hardened for superior hardness and rust resistance, providing outstanding working performance and reliability for both small and large workpieces.
High Precision: A high-precision machining process is used to ensure the structural stability and machining accuracy of the three-jaw chuck. The self-centering lathe incorporates a delicate bevel gear and three pinion gears, which help to achieve precise machining processes. The bearing tolerance is ≤0.05mm/0.002inch.
Inner and outer jaws: The 3-jaw self-centering lathe chuck is equipped with an inner jaw and an outer jaw to expand its clamping range, and the outer jaws can clamp larger industrial parts. Clamping range: 0.1-5 inches/2.5-125 mm. All you need to do is rotate it using the T-key and adjust it to fit the size and shape of your workpiece.
Simple and easy to use: The 3-jaw lathe chuck has a simple and compact structure, striving for the best balance between function and reliability. The built-in self-centering function allows you to use it without repeated calibration. All you need to do is install it in the correct order and use it with peace of mind.
