Meet the 4 Jaw Lathe Chuck, a self-centering chuck engineered for precision and durability in metalworking, woodworking, and small-scale manufacturing. Available in two outer diameters (2.75" and 3.75"), it fits common spindle sizes while delivering stable, repeatable clamping for a wide range of workpieces. Crafted from high-strength #45 steel and chrome-plated for rust resistance, this chuck is designed to endure daily workshop use with minimal wear. All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.

Its compact, robust design combines simple installation with reliable performance. The lathe chuck's four-jaw, self-centering arrangement guarantees balanced grip on round and irregular parts alike, helping you achieve true runout and clean finishes. The precision machining ensures tight tolerances and stable operation across turning, grinding, and drilling tasks. This makes it a versatile upgrade for hobbyists and professionals alike.
